2 Number of children

3 Number of previous CS

4 Anterior uterine wall thickness

uterine space Non surgical tt

5 Expertise of the clinicians

Aboubakr Elnashar

Gynecologic surgeons laparoscopy and hysteroscopy or laparotomy Obstetricians radiologists and IVF specialists IM MTX or US local MTX (or Kcl) UAE occasionally

Aboubakr Elnashar

Counseling of the patient

Immediate and decisive action to prevent further

growth of the embryo or fetus

Options

1 Continuation of the pregnancy

Successful births

uneventful term pregnancy poor

Hysterectomy rate 71

increased risk of placenta previaaccreta and

massive hge

Aboubakr Elnashar

2 Termination of the pregnancy in 1st T

Substantial hge 20-40

Hysterectomy substantially lower

Termination Recommended particularly when

Early evidence of progression toward the abdominal

cavity or bladder

increased risk of life-threatening complications and

loss of fertility

Aboubakr Elnashar

Potential complications

751 cases reviewed 218 resulted in major surgery or interventional

radiology procedures (primary or emergency) The total planned primary (nonemergency) interventions performed were 66 (87) which included 3 hysterectomies 14 laparotomies and 49 uterine artery embolizations or ligations There were 98 (130) emergency interventions which included 36 hysterectomies 40 laparotomies and 22 uterine artery embolizations or ligations (Timor-Tritsch et al 2014)

(Immediate or delayed) Need secondary tt for blood loss ge200 mL or blood transfusion Complications are most often when the following

tt used alone

bull Single IM MTX

bull DampC

bull UAE Aboubakr Elnashar

lowest complication rate

1 Local and US directed MTX injection with or

without additional IM MTX

2 Surgical excision by hysteroscopic guidance

Aboubakr Elnashar

Management approaches I Surgical Excision Laparotomy or Hysterectomy or Laparoscopic or Hysteroscopic followed by DampC II Minimally invasive local injection of MTX or Kcl or UAE in combination with IM MTX Medical tt alone not recommended

Aboubakr Elnashar

Medical 1 Systemic single-dose MTX 1 mgkg or 50 mgm2 of body surface area complication rate 646 second tt when the fetal heart beat did not cease after several days

High failure rate slow action and questionable ability to stop cardiac activity and placental expansion The expected result can take days and all the while GS the embryo or fetus and its vascularity are growing Secondary tt has to address a larger gestation with more abundant vascularization

Aboubakr Elnashar

Systemic MTX as a single tt should be avoided 1 Waiting days for its effect to stop the heart beats which may not happen 2 It also led to the additional growth of the embryofetus as well as the vascularization of GS 3 Wastes precious time

Aboubakr Elnashar

2 Systemic multidose sequential MTX Two to three IM (1 mgkg BW or 50 mgmm2 of surface area) at an interval of 2 or 3 days over the course of a week

Cumulative adverse effects on the liver and bone marrow Success rate 75 Hysterectomy 6 Best results βHCG le 5000 mUmL Fibrous tissue within the scar around GS can delay systemic MTX absorption into GS Aboubakr Elnashar

Minimally invasive

1 Intragestational-sac injection of MTX or Kcl

with US guidance

Indications

hemodynamically stable

unruptured CSP

le8w gestation

myometrial thickness between GS and bladder

le 2 mm

Aboubakr Elnashar

Approach

TV approach is favored over TA

1 better visualization of the needle 2 shorter distance to reach the sac 3 decreased risk of bladder injury TAS guidance slighter higher complication rate (15) than those

using TVS guidance

Aboubakr Elnashar

Steps

1 After confirming the placement of needle 25 mg

of MTX in 1 mL of solution is injected slowly in

the GS

2 25 mg is injected outside GS as the needle is

withdrawn preferably the placental site

3 TVS 60-90 m after the procedure confirm

cessation of FH and to identify local bleeding

4 IM of 25 mg MTX (for a total combined dose of

75 mg) before discharge from our unit

5 24-48 h follow-up scan Close monitoring

hge may still occur

Aboubakr Elnashar

TVS -guided intragestational-sac injection of MTX in a

live CSP at 6 w 4 days The arrow points to the needle

in place (F = fetus) Aboubakr Elnashar

Advantages

No anesthesia

Complications fewest 108

most effective intervention

decrease the need for additional interventions

provides a higher concentration of the

embryocide locally

avoidance of systemic side effects

more rapid interruption of the pregnancy

Aboubakr Elnashar

Aspiration of gestational sac fluid injection of methotrexate in the sac injection of homeostatic agent and pituitrin in the uterine muscle layer and injection of triple anti-inflammatory drugs around the uterus in 12 patients with CSP (Kong et al 2014)

Ultrasonography-guided multidrug interventional therapy for CSP is a new safe effective minimally invasive method

2 Use of a Foley balloon catheter

Indications

1 Alone (usually in gestations of 5ndash7 w) in the

hope of stopping the evolution of the pregnancy

by placing pressure on a small GS

2 In conjunction with another tt

3 Backup if bleeding occurs

French-12 size 10-mL silicone balloon catheter or French-14 catheter with a 30-mL balloon

Aboubakr Elnashar

balloon inflated with 5

of the inflated balloon

(B) in a case of a CSP at

6 w 4 days after

injection of MXT

Aboubakr Elnashar

Steps GA not required TAS guidance Or TVS guidance allow for more precise placement and assess the pressure avoiding over inflation of the balloon Catheter is kept 24 to 48 h with the outer end of the catheter fastened to the patientrsquos thigh Antibiotics Reevaluate after 48H Aboubakr Elnashar

3 UAE alone or in combination Indication 1 As a rescue procedure in the case of significant

bleeding or an A-VM 2 Concurrent with MTH Not as a primary tt delay between tt and effect allows the gestation to

grow and vascularity to increase Disadvantages 1 GA 2 Complication rate 47 3 Not the best 1st -line tt

Aboubakr Elnashar

Surgical excision

laparoscopy or laparotomy may be best tt

No response to conservative medical tt

Patient late to present

Allows for revision of the CS scar with new uterine closure that may minimize risk of recurrence Risks postoperative adhesions impair future fertility increased size of surgical wounds longer hospital stay and recovery increased risk of future placenta previaaccreta

Aboubakr Elnashar

Aboubakr Elnashar

1 Excision by laparotomy alone or in combination with hysteroscopy

18 cases 5 complications and only when used in an emergency situation

Aboubakr Elnashar

2 Laparoscopic excision Complication rate 306 Laparoscopy combined with hysteroscopy Complication rate 20

Aboubakr Elnashar

3 Hysteroscopy alone or in combination complication rate 138 Hysteroscopy combined with TA US guidance 9 cases no complications reasonable operative solution Hysteroscopy combined with mifepristone complication rate17

Aboubakr Elnashar

4 Suction aspiration or DampC alone or in

combination

Isolated D amp C should be avoided

1 Trophoblastic tissue and villi are implanted

within the myometrium D ampC is unlikely to expel

the GS without rupturing the uterine wall or

damaging the bladder

2 massive bleeding emergency laparotomies

loss of the uterus

3 exposed vessels in the cervical scar tissue bleed no muscle grid to contract and contain the profuse bleeding

4 Complication rate 62 (29ndash86)

bleeding complications necessitating 3rd -line tt that almost always was surgical Aboubakr Elnashar

MTX followed by suction curettage Mean blood loss 707 mL (100ndash2000 mL) tt failure 3 out of 45 despite insertion of a Foley balloon catheter If DampC is still the preferred tt of choice blood products should be available balloon catheter should be inserted in the cervix

Preoperative determination of CSP implantation depth and extent is important in selecting candidates for surgical treatment Primary single-step surgical evacuation was successful in most patients with superficial implantation but patients should be informed of the possibility of salvage interventions before undergoing surgical evacuation (Kong et

al 2014)

Aboubakr Elnashar

FOLLOW-UP Placenta is implanted mostly within fibrous

tissue absorption of the GS is slow after med tt

1 9 w to obtain clearance of βHCG

2 3 months for clearance of GS on TVS

1 βHCG weekly until it is undetectable

2 TVS Monthly to evaluate the size of retained

products of conception

Aboubakr Elnashar

3 SIS in a nonpregnant patient uterine wall integrity size of the cesarean scar which may relate to the possibility of uterine scar complications in future pregnancies 4 Early TVS After CSP After CS to confirm an intrauterine location of the new gestation

Aboubakr Elnashar

5 Avoiding pregnancy No guidelines 12 to 24 months 6 Repair of scar before future pregnancies not known whether required or not Severely deficient uterine scars 10 of women who have had prior CS but CSP are much more rare

Aboubakr Elnashar

Outcomes Uneventful viable pregnancies have been reported after all modalities of conservative management Recurrence rate 5 IU pregnancy 95 spontaneous pregnancy 88 Normal pregnancy 65 Spontaneous abortion 35 higher than expected

Aboubakr Elnashar

4 PREVENTION OF CSP

1 Surgical repair of the uterine dehiscence (niche) in patients with previous CS while not pregnant

Ben Nagi et al reported on a successful surgical repair Donnez et al hysteroscopic repair Klemm et al laparoscopic-assisted vaginal repair Yalcinkaya et al robotic-assisted laparoscopic repair More research is necessary before making recommendations for such surgical tt to prevent CSP

Aboubakr Elnashar

2 Specific surgical technique single- or double-layer closure of the incision can minimize or avoid a CSP

Aboubakr Elnashar

SUMMARY CSP

An uncommon but potentially life-threatening

The incidence is rising as CSR is rising

Precursor of morbidly adherent placenta

Do not confuse CSP with ectopic pregnancy

Early diagnosis is important TVS is the most

effective and preferred diagnostic tool

A key first step Determine whether heart activity is

present

Aboubakr Elnashar

If heart activity is documented Counsel the patient

inform the patient of the risks of pregnancy

continuation

If continuation an additional counseling session

risks

If termination a reliable tt that stops fetal heart beat

without delay

Avoid single tts unlikely to be effective

DampC

suction curettage

single-dose IM MTX and

UAE

Aboubakr Elnashar

Consider combination treatments best results

direct injection of MTX or Kcl into GS with TVS

guidance

Keep a catheter at hand

At the time of discharging after a CS in a future

pregnancy an early visit for TVS is important

Abstract

Heterotopic cesarean scar pregnancy is a rare life-threatening form of

ectopic pregnancy To provide information regarding the clinical

manifestations diagnosis management and prognosis of this condition

we reviewed all cases reported in the English literature All literature on

heterotopic cesarean scar pregnancy was retrieved by searching the

PubMed database and tracking references of the relevant literature Full

texts were reviewed and clinical manifestations diagnostic methods and

the relationship between the treatment and prognosis were summarized A

total of 14 patients with heterotopic cesarean scar pregnancies were

identified including 6 spontaneous pregnancies and 8 following in vitro

fertilization-embryo transfer Gestational ages at diagnosis ranged from 5

weeks to 8 weeks 4 days Only 5 cases presented with vaginal bleeding

and the others were asymptomatic All 14 cases were diagnosed by

transvaginal sonography One patient with no future fertility requirements

underwent pregnancy termination by methotrexate Of the remaining 13

patients who desired to preserve their intrauterine gestations 10 were

treated by sonographically guided selective embryo reduction in situ (by

possible prognostic factors

DESIGN

Retrospective consecutive cohort study

SETTING

Tertiary care university hospital

SUBJECT(S)

A cohort of patients with CSP and clear ultrasound images who underwent

primary surgical evacuation from January 2000 to December 2012

INTERVENTION(S)

Patients fulfilling the ultrasound criteria of CSP were further classified into

superficial and deep groups according to their implantation locations and

extents The final decision on the method of treatment including

methotrexate chemotherapy surgical evacuation and others was made by

the patients after consultation with the physician Pretreatment patient

III For treatment of CSP all are correct

except

1Anterior uterine wall thickness is important

2With pregnancy continuation hysterectomy

rate is 17

3Termination of the pregnancy in first

trimester is recommended

4Immediate and decisive action is

recommended

Aboubakr Elnashar

IV All are correct regarding CSP treatment

except

1 Complications are most often when single

IM Methotrexate or DampC

2 Complications are at lowest rate with

Local and US directed MTX injection with

or without additional IM MTX

3 Use of a Foley balloon catheter is not

recommended

4 laparoscopy or laparotomy with excision

of the pregnancy may be best treatment

Aboubakr Elnashar

V For follow up after treatment of CSP

all are correct except 1 5 w are required to obtain clearance of

βHCG

2 TVS is done monthly to evaluate the size

of retained products of conception

3 Avoiding pregnancy for 12 to 24 months

4 In a future pregnancy an early visit for

TVS is important

1 Surgical repair of the uterine dehiscence (niche) in patients with previous CS while not pregnant

Ben Nagi et al reported on a successful surgical repair Donnez et al hysteroscopic repair Klemm et al laparoscopic-assisted vaginal repair Yalcinkaya et al robotic-assisted laparoscopic repair More research is necessary before making recommendations for such surgical tt to prevent CSP

Aboubakr Elnashar

2 Specific surgical technique single- or double-layer closure of the incision can minimize or avoid a CSP

Aboubakr Elnashar

SUMMARY CSP

An uncommon but potentially life-threatening

The incidence is rising as CSR is rising

Precursor of morbidly adherent placenta

Do not confuse CSP with ectopic pregnancy

Early diagnosis is important TVS is the most

effective and preferred diagnostic tool

A key first step Determine whether heart activity is

present

Aboubakr Elnashar

If heart activity is documented Counsel the patient

inform the patient of the risks of pregnancy

continuation

If continuation an additional counseling session

risks

If termination a reliable tt that stops fetal heart beat

without delay

Avoid single tts unlikely to be effective

DampC

suction curettage

single-dose IM MTX and

UAE

Aboubakr Elnashar

Consider combination treatments best results

direct injection of MTX or Kcl into GS with TVS

guidance

Keep a catheter at hand

At the time of discharging after a CS in a future

pregnancy an early visit for TVS is important

Abstract

Heterotopic cesarean scar pregnancy is a rare life-threatening form of

ectopic pregnancy To provide information regarding the clinical

manifestations diagnosis management and prognosis of this condition

we reviewed all cases reported in the English literature All literature on

heterotopic cesarean scar pregnancy was retrieved by searching the

PubMed database and tracking references of the relevant literature Full

texts were reviewed and clinical manifestations diagnostic methods and

the relationship between the treatment and prognosis were summarized A

total of 14 patients with heterotopic cesarean scar pregnancies were

identified including 6 spontaneous pregnancies and 8 following in vitro

fertilization-embryo transfer Gestational ages at diagnosis ranged from 5

weeks to 8 weeks 4 days Only 5 cases presented with vaginal bleeding

and the others were asymptomatic All 14 cases were diagnosed by

transvaginal sonography One patient with no future fertility requirements

underwent pregnancy termination by methotrexate Of the remaining 13

patients who desired to preserve their intrauterine gestations 10 were

treated by sonographically guided selective embryo reduction in situ (by

Abstract

OBJECTIVE

To assess the efficacy and safety of primary surgical evacuation therapy

for cesarean scarpregnancy (CSP) of the first trimester and to evaluate its

possible prognostic factors

DESIGN

Retrospective consecutive cohort study

SETTING

Tertiary care university hospital

SUBJECT(S)

A cohort of patients with CSP and clear ultrasound images who underwent

primary surgical evacuation from January 2000 to December 2012

INTERVENTION(S)

Patients fulfilling the ultrasound criteria of CSP were further classified into

superficial and deep groups according to their implantation locations and

extents The final decision on the method of treatment including

methotrexate chemotherapy surgical evacuation and others was made by

the patients after consultation with the physician Pretreatment patient

eliminating GS

preserving fertility

No universal tt guidelines

No clear conclusion

most effective

least or no complications

Aboubakr Elnashar

Timor-Tritsch et al 2014 Aboubakr Elnashar

Treatment should be individualized based on

1 Patientrsquos age

2 Number of children

3 Number of previous CS

4 Anterior uterine wall thickness

when the trophoblast reaches the bladder-

uterine space Non surgical tt

5 Expertise of the clinicians

Aboubakr Elnashar

Gynecologic surgeons laparoscopy and hysteroscopy or laparotomy Obstetricians radiologists and IVF specialists IM MTX or US local MTX (or Kcl) UAE occasionally

Aboubakr Elnashar

Counseling of the patient

Immediate and decisive action to prevent further

growth of the embryo or fetus

Options

1 Continuation of the pregnancy

Successful births

uneventful term pregnancy poor

Hysterectomy rate 71

increased risk of placenta previaaccreta and

massive hge

Aboubakr Elnashar

2 Termination of the pregnancy in 1st T

Substantial hge 20-40

Hysterectomy substantially lower

Termination Recommended particularly when

Early evidence of progression toward the abdominal

cavity or bladder

increased risk of life-threatening complications and

loss of fertility

Aboubakr Elnashar

Potential complications

751 cases reviewed 218 resulted in major surgery or interventional

radiology procedures (primary or emergency) The total planned primary (nonemergency) interventions performed were 66 (87) which included 3 hysterectomies 14 laparotomies and 49 uterine artery embolizations or ligations There were 98 (130) emergency interventions which included 36 hysterectomies 40 laparotomies and 22 uterine artery embolizations or ligations (Timor-Tritsch et al 2014)

(Immediate or delayed) Need secondary tt for blood loss ge200 mL or blood transfusion Complications are most often when the following

tt used alone

bull Single IM MTX

bull DampC

bull UAE Aboubakr Elnashar

lowest complication rate

1 Local and US directed MTX injection with or

without additional IM MTX

2 Surgical excision by hysteroscopic guidance

Aboubakr Elnashar

Management approaches I Surgical Excision Laparotomy or Hysterectomy or Laparoscopic or Hysteroscopic followed by DampC II Minimally invasive local injection of MTX or Kcl or UAE in combination with IM MTX Medical tt alone not recommended

Aboubakr Elnashar

Medical 1 Systemic single-dose MTX 1 mgkg or 50 mgm2 of body surface area complication rate 646 second tt when the fetal heart beat did not cease after several days

High failure rate slow action and questionable ability to stop cardiac activity and placental expansion The expected result can take days and all the while GS the embryo or fetus and its vascularity are growing Secondary tt has to address a larger gestation with more abundant vascularization

Aboubakr Elnashar

Systemic MTX as a single tt should be avoided 1 Waiting days for its effect to stop the heart beats which may not happen 2 It also led to the additional growth of the embryofetus as well as the vascularization of GS 3 Wastes precious time

Aboubakr Elnashar

2 Systemic multidose sequential MTX Two to three IM (1 mgkg BW or 50 mgmm2 of surface area) at an interval of 2 or 3 days over the course of a week

Cumulative adverse effects on the liver and bone marrow Success rate 75 Hysterectomy 6 Best results βHCG le 5000 mUmL Fibrous tissue within the scar around GS can delay systemic MTX absorption into GS Aboubakr Elnashar

Minimally invasive

1 Intragestational-sac injection of MTX or Kcl

with US guidance

Indications

hemodynamically stable

unruptured CSP

le8w gestation

myometrial thickness between GS and bladder

le 2 mm

Aboubakr Elnashar

Approach

TV approach is favored over TA

1 better visualization of the needle 2 shorter distance to reach the sac 3 decreased risk of bladder injury TAS guidance slighter higher complication rate (15) than those

using TVS guidance

Aboubakr Elnashar

Steps

1 After confirming the placement of needle 25 mg

of MTX in 1 mL of solution is injected slowly in

the GS

2 25 mg is injected outside GS as the needle is

withdrawn preferably the placental site

3 TVS 60-90 m after the procedure confirm

cessation of FH and to identify local bleeding

4 IM of 25 mg MTX (for a total combined dose of

75 mg) before discharge from our unit

5 24-48 h follow-up scan Close monitoring

hge may still occur

Aboubakr Elnashar

TVS -guided intragestational-sac injection of MTX in a

live CSP at 6 w 4 days The arrow points to the needle

in place (F = fetus) Aboubakr Elnashar

Advantages

No anesthesia

Complications fewest 108

most effective intervention

decrease the need for additional interventions

provides a higher concentration of the

embryocide locally

avoidance of systemic side effects

more rapid interruption of the pregnancy

Aboubakr Elnashar

Aspiration of gestational sac fluid injection of methotrexate in the sac injection of homeostatic agent and pituitrin in the uterine muscle layer and injection of triple anti-inflammatory drugs around the uterus in 12 patients with CSP (Kong et al 2014)

Ultrasonography-guided multidrug interventional therapy for CSP is a new safe effective minimally invasive method

2 Use of a Foley balloon catheter

Indications

1 Alone (usually in gestations of 5ndash7 w) in the

hope of stopping the evolution of the pregnancy

by placing pressure on a small GS

2 In conjunction with another tt

3 Backup if bleeding occurs

French-12 size 10-mL silicone balloon catheter or French-14 catheter with a 30-mL balloon

Aboubakr Elnashar

balloon inflated with 5

mL of saline

TV power Doppler image

of the inflated balloon

(B) in a case of a CSP at

6 w 4 days after

injection of MXT

Aboubakr Elnashar

Steps GA not required TAS guidance Or TVS guidance allow for more precise placement and assess the pressure avoiding over inflation of the balloon Catheter is kept 24 to 48 h with the outer end of the catheter fastened to the patientrsquos thigh Antibiotics Reevaluate after 48H Aboubakr Elnashar

3 UAE alone or in combination Indication 1 As a rescue procedure in the case of significant

bleeding or an A-VM 2 Concurrent with MTH Not as a primary tt delay between tt and effect allows the gestation to

grow and vascularity to increase Disadvantages 1 GA 2 Complication rate 47 3 Not the best 1st -line tt

Aboubakr Elnashar

Surgical excision

laparoscopy or laparotomy may be best tt

No response to conservative medical tt

Patient late to present

Allows for revision of the CS scar with new uterine closure that may minimize risk of recurrence Risks postoperative adhesions impair future fertility increased size of surgical wounds longer hospital stay and recovery increased risk of future placenta previaaccreta

Aboubakr Elnashar

Aboubakr Elnashar

1 Excision by laparotomy alone or in combination with hysteroscopy

18 cases 5 complications and only when used in an emergency situation

Aboubakr Elnashar

2 Laparoscopic excision Complication rate 306 Laparoscopy combined with hysteroscopy Complication rate 20

Aboubakr Elnashar

3 Hysteroscopy alone or in combination complication rate 138 Hysteroscopy combined with TA US guidance 9 cases no complications reasonable operative solution Hysteroscopy combined with mifepristone complication rate17

Aboubakr Elnashar

4 Suction aspiration or DampC alone or in

combination

Isolated D amp C should be avoided

1 Trophoblastic tissue and villi are implanted

within the myometrium D ampC is unlikely to expel

the GS without rupturing the uterine wall or

damaging the bladder

2 massive bleeding emergency laparotomies

loss of the uterus

3 exposed vessels in the cervical scar tissue bleed no muscle grid to contract and contain the profuse bleeding

4 Complication rate 62 (29ndash86)

bleeding complications necessitating 3rd -line tt that almost always was surgical Aboubakr Elnashar

MTX followed by suction curettage Mean blood loss 707 mL (100ndash2000 mL) tt failure 3 out of 45 despite insertion of a Foley balloon catheter If DampC is still the preferred tt of choice blood products should be available balloon catheter should be inserted in the cervix

Preoperative determination of CSP implantation depth and extent is important in selecting candidates for surgical treatment Primary single-step surgical evacuation was successful in most patients with superficial implantation but patients should be informed of the possibility of salvage interventions before undergoing surgical evacuation (Kong et

al 2014)

Aboubakr Elnashar

FOLLOW-UP Placenta is implanted mostly within fibrous

tissue absorption of the GS is slow after med tt

Aboubakr Elnashar

Medical 1 Systemic single-dose MTX 1 mgkg or 50 mgm2 of body surface area complication rate 646 second tt when the fetal heart beat did not cease after several days

High failure rate slow action and questionable ability to stop cardiac activity and placental expansion The expected result can take days and all the while GS the embryo or fetus and its vascularity are growing Secondary tt has to address a larger gestation with more abundant vascularization

Aboubakr Elnashar

Systemic MTX as a single tt should be avoided 1 Waiting days for its effect to stop the heart beats which may not happen 2 It also led to the additional growth of the embryofetus as well as the vascularization of GS 3 Wastes precious time

Aboubakr Elnashar

2 Systemic multidose sequential MTX Two to three IM (1 mgkg BW or 50 mgmm2 of surface area) at an interval of 2 or 3 days over the course of a week

Cumulative adverse effects on the liver and bone marrow Success rate 75 Hysterectomy 6 Best results βHCG le 5000 mUmL Fibrous tissue within the scar around GS can delay systemic MTX absorption into GS Aboubakr Elnashar

Aboubakr Elnashar

Approach

TV approach is favored over TA

1 better visualization of the needle 2 shorter distance to reach the sac 3 decreased risk of bladder injury TAS guidance slighter higher complication rate (15) than those

using TVS guidance

Aboubakr Elnashar

Steps

1 After confirming the placement of needle 25 mg

of MTX in 1 mL of solution is injected slowly in

the GS

2 25 mg is injected outside GS as the needle is

withdrawn preferably the placental site

3 TVS 60-90 m after the procedure confirm

cessation of FH and to identify local bleeding

4 IM of 25 mg MTX (for a total combined dose of

75 mg) before discharge from our unit

Aboubakr Elnashar

Aspiration of gestational sac fluid injection of methotrexate in the sac injection of homeostatic agent and pituitrin in the uterine muscle layer and injection of triple anti-inflammatory drugs around the uterus in 12 patients with CSP (Kong et al 2014)

Ultrasonography-guided multidrug interventional therapy for CSP is a new safe effective minimally invasive method

2 Use of a Foley balloon catheter

Indications

1 Alone (usually in gestations of 5ndash7 w) in the

hope of stopping the evolution of the pregnancy

by placing pressure on a small GS

2 In conjunction with another tt

4 Suction aspiration or DampC alone or in

combination

Isolated D amp C should be avoided

1 Trophoblastic tissue and villi are implanted

the GS without rupturing the uterine wall or

damaging the bladder

2 massive bleeding emergency laparotomies

3 exposed vessels in the cervical scar tissue bleed no muscle grid to contract and contain the profuse bleeding

4 Complication rate 62 (29ndash86)

MTX followed by suction curettage Mean blood loss 707 mL (100ndash2000 mL) tt failure 3 out of 45 despite insertion of a Foley balloon catheter If DampC is still the preferred tt of choice blood products should be available balloon catheter should be inserted in the cervix

Preoperative determination of CSP implantation depth and extent is important in selecting candidates for surgical treatment Primary single-step surgical evacuation was successful in most patients with superficial implantation but patients should be informed of the possibility of salvage interventions before undergoing surgical evacuation (Kong et

al 2014)

Aboubakr Elnashar

FOLLOW-UP Placenta is implanted mostly within fibrous

tissue absorption of the GS is slow after med tt

1 9 w to obtain clearance of βHCG

2 3 months for clearance of GS on TVS

1 βHCG weekly until it is undetectable

2 TVS Monthly to evaluate the size of retained

products of conception

Aboubakr Elnashar

3 SIS in a nonpregnant patient uterine wall integrity size of the cesarean scar which may relate to the possibility of uterine scar complications in future pregnancies 4 Early TVS After CSP After CS to confirm an intrauterine location of the new gestation

Aboubakr Elnashar

5 Avoiding pregnancy No guidelines 12 to 24 months 6 Repair of scar before future pregnancies not known whether required or not Severely deficient uterine scars 10 of women who have had prior CS but CSP are much more rare

Aboubakr Elnashar

Outcomes Uneventful viable pregnancies have been reported after all modalities of conservative management Recurrence rate 5 IU pregnancy 95 spontaneous pregnancy 88 Normal pregnancy 65 Spontaneous abortion 35 higher than expected

Aboubakr Elnashar

4 PREVENTION OF CSP

1 Surgical repair of the uterine dehiscence (niche) in patients with previous CS while not pregnant

Ben Nagi et al reported on a successful surgical repair Donnez et al hysteroscopic repair Klemm et al laparoscopic-assisted vaginal repair Yalcinkaya et al robotic-assisted laparoscopic repair More research is necessary before making recommendations for such surgical tt to prevent CSP

Aboubakr Elnashar

2 Specific surgical technique single- or double-layer closure of the incision can minimize or avoid a CSP

Aboubakr Elnashar

SUMMARY CSP

An uncommon but potentially life-threatening

The incidence is rising as CSR is rising

Precursor of morbidly adherent placenta

Do not confuse CSP with ectopic pregnancy

Early diagnosis is important TVS is the most

effective and preferred diagnostic tool

A key first step Determine whether heart activity is

present

Aboubakr Elnashar

If heart activity is documented Counsel the patient

inform the patient of the risks of pregnancy

continuation

If continuation an additional counseling session

risks

If termination a reliable tt that stops fetal heart beat

without delay

Avoid single tts unlikely to be effective

DampC

suction curettage

single-dose IM MTX and

UAE

Aboubakr Elnashar

Consider combination treatments best results

direct injection of MTX or Kcl into GS with TVS

guidance

Keep a catheter at hand

At the time of discharging after a CS in a future

pregnancy an early visit for TVS is important

Abstract

Heterotopic cesarean scar pregnancy is a rare life-threatening form of

ectopic pregnancy To provide information regarding the clinical

manifestations diagnosis management and prognosis of this condition

we reviewed all cases reported in the English literature All literature on

heterotopic cesarean scar pregnancy was retrieved by searching the

PubMed database and tracking references of the relevant literature Full

texts were reviewed and clinical manifestations diagnostic methods and

the relationship between the treatment and prognosis were summarized A

total of 14 patients with heterotopic cesarean scar pregnancies were

identified including 6 spontaneous pregnancies and 8 following in vitro

fertilization-embryo transfer Gestational ages at diagnosis ranged from 5

weeks to 8 weeks 4 days Only 5 cases presented with vaginal bleeding

and the others were asymptomatic All 14 cases were diagnosed by

transvaginal sonography One patient with no future fertility requirements

underwent pregnancy termination by methotrexate Of the remaining 13

patients who desired to preserve their intrauterine gestations 10 were

treated by sonographically guided selective embryo reduction in situ (by

Abstract

Heterotopic cesarean scar pregnancy is a rare life-threatening form of

ectopic pregnancy To provide information regarding the clinical

manifestations diagnosis management and prognosis of this condition

we reviewed all cases reported in the English literature All literature on

heterotopic cesarean scar pregnancy was retrieved by searching the

PubMed database and tracking references of the relevant literature Full

texts were reviewed and clinical manifestations diagnostic methods and

the relationship between the treatment and prognosis were summarized A

total of 14 patients with heterotopic cesarean scar pregnancies were

identified including 6 spontaneous pregnancies and 8 following in vitro

fertilization-embryo transfer Gestational ages at diagnosis ranged from 5

weeks to 8 weeks 4 days Only 5 cases presented with vaginal bleeding

and the others were asymptomatic All 14 cases were diagnosed by

transvaginal sonography One patient with no future fertility requirements

underwent pregnancy termination by methotrexate Of the remaining 13

patients who desired to preserve their intrauterine gestations 10 were

treated by sonographically guided selective embryo reduction in situ (by

Abstract

OBJECTIVE

To assess the efficacy and safety of primary surgical evacuation therapy

for cesarean scarpregnancy (CSP) of the first trimester and to evaluate its

possible prognostic factors

DESIGN

Retrospective consecutive cohort study

SETTING

Tertiary care university hospital

SUBJECT(S)

A cohort of patients with CSP and clear ultrasound images who underwent

primary surgical evacuation from January 2000 to December 2012

INTERVENTION(S)

Patients fulfilling the ultrasound criteria of CSP were further classified into

superficial and deep groups according to their implantation locations and

extents The final decision on the method of treatment including

methotrexate chemotherapy surgical evacuation and others was made by

the patients after consultation with the physician Pretreatment patient

III For treatment of CSP all are correct

except

1Anterior uterine wall thickness is important

2With pregnancy continuation hysterectomy

rate is 17

3Termination of the pregnancy in first

trimester is recommended

4Immediate and decisive action is

recommended

Aboubakr Elnashar

IV All are correct regarding CSP treatment

except

1 Complications are most often when single

IM Methotrexate or DampC

2 Complications are at lowest rate with

Local and US directed MTX injection with

or without additional IM MTX

3 Use of a Foley balloon catheter is not

recommended

4 laparoscopy or laparotomy with excision

of the pregnancy may be best treatment

Aboubakr Elnashar

V For follow up after treatment of CSP

all are correct except 1 5 w are required to obtain clearance of

βHCG

2 TVS is done monthly to evaluate the size

of retained products of conception

3 Avoiding pregnancy for 12 to 24 months

4 In a future pregnancy an early visit for

TVS is important

Abstract

Heterotopic cesarean scar pregnancy is a rare life-threatening form of

ectopic pregnancy To provide information regarding the clinical

manifestations diagnosis management and prognosis of this condition

we reviewed all cases reported in the English literature All literature on

heterotopic cesarean scar pregnancy was retrieved by searching the

PubMed database and tracking references of the relevant literature Full

texts were reviewed and clinical manifestations diagnostic methods and

the relationship between the treatment and prognosis were summarized A

total of 14 patients with heterotopic cesarean scar pregnancies were

identified including 6 spontaneous pregnancies and 8 following in vitro

fertilization-embryo transfer Gestational ages at diagnosis ranged from 5

weeks to 8 weeks 4 days Only 5 cases presented with vaginal bleeding

and the others were asymptomatic All 14 cases were diagnosed by

transvaginal sonography One patient with no future fertility requirements

underwent pregnancy termination by methotrexate Of the remaining 13

patients who desired to preserve their intrauterine gestations 10 were

treated by sonographically guided selective embryo reduction in situ (by

preserving fertility

No universal tt guidelines

No clear conclusion

most effective

least or no complications

Aboubakr Elnashar

Timor-Tritsch et al 2014 Aboubakr Elnashar

Treatment should be individualized based on

1 Patientrsquos age

2 Number of children

3 Number of previous CS

4 Anterior uterine wall thickness

when the trophoblast reaches the bladder-

uterine space Non surgical tt

5 Expertise of the clinicians

Aboubakr Elnashar

Gynecologic surgeons laparoscopy and hysteroscopy or laparotomy Obstetricians radiologists and IVF specialists IM MTX or US local MTX (or Kcl) UAE occasionally

Aboubakr Elnashar

Counseling of the patient

Immediate and decisive action to prevent further

growth of the embryo or fetus

Options

1 Continuation of the pregnancy

Successful births

uneventful term pregnancy poor

Hysterectomy rate 71

increased risk of placenta previaaccreta and

massive hge

Aboubakr Elnashar

2 Termination of the pregnancy in 1st T

Substantial hge 20-40

Hysterectomy substantially lower

Termination Recommended particularly when

Early evidence of progression toward the abdominal

cavity or bladder

increased risk of life-threatening complications and

loss of fertility

Aboubakr Elnashar

Potential complications

751 cases reviewed 218 resulted in major surgery or interventional

radiology procedures (primary or emergency) The total planned primary (nonemergency) interventions performed were 66 (87) which included 3 hysterectomies 14 laparotomies and 49 uterine artery embolizations or ligations There were 98 (130) emergency interventions which included 36 hysterectomies 40 laparotomies and 22 uterine artery embolizations or ligations (Timor-Tritsch et al 2014)

(Immediate or delayed) Need secondary tt for blood loss ge200 mL or blood transfusion Complications are most often when the following

tt used alone

bull Single IM MTX

bull DampC

bull UAE Aboubakr Elnashar

lowest complication rate

1 Local and US directed MTX injection with or

without additional IM MTX

2 Surgical excision by hysteroscopic guidance

Aboubakr Elnashar

Management approaches I Surgical Excision Laparotomy or Hysterectomy or Laparoscopic or Hysteroscopic followed by DampC II Minimally invasive local injection of MTX or Kcl or UAE in combination with IM MTX Medical tt alone not recommended

Aboubakr Elnashar

Medical 1 Systemic single-dose MTX 1 mgkg or 50 mgm2 of body surface area complication rate 646 second tt when the fetal heart beat did not cease after several days

High failure rate slow action and questionable ability to stop cardiac activity and placental expansion The expected result can take days and all the while GS the embryo or fetus and its vascularity are growing Secondary tt has to address a larger gestation with more abundant vascularization

Aboubakr Elnashar

Systemic MTX as a single tt should be avoided 1 Waiting days for its effect to stop the heart beats which may not happen 2 It also led to the additional growth of the embryofetus as well as the vascularization of GS 3 Wastes precious time

Aboubakr Elnashar

2 Systemic multidose sequential MTX Two to three IM (1 mgkg BW or 50 mgmm2 of surface area) at an interval of 2 or 3 days over the course of a week

Cumulative adverse effects on the liver and bone marrow Success rate 75 Hysterectomy 6 Best results βHCG le 5000 mUmL Fibrous tissue within the scar around GS can delay systemic MTX absorption into GS Aboubakr Elnashar

Minimally invasive

1 Intragestational-sac injection of MTX or Kcl

with US guidance

Indications

hemodynamically stable

unruptured CSP

le8w gestation

myometrial thickness between GS and bladder

le 2 mm

Aboubakr Elnashar

Approach

TV approach is favored over TA

1 better visualization of the needle 2 shorter distance to reach the sac 3 decreased risk of bladder injury TAS guidance slighter higher complication rate (15) than those

using TVS guidance

Aboubakr Elnashar

Steps

1 After confirming the placement of needle 25 mg

of MTX in 1 mL of solution is injected slowly in

the GS

2 25 mg is injected outside GS as the needle is

withdrawn preferably the placental site

3 TVS 60-90 m after the procedure confirm

cessation of FH and to identify local bleeding

4 IM of 25 mg MTX (for a total combined dose of

75 mg) before discharge from our unit

5 24-48 h follow-up scan Close monitoring

hge may still occur

Aboubakr Elnashar

TVS -guided intragestational-sac injection of MTX in a

live CSP at 6 w 4 days The arrow points to the needle

in place (F = fetus) Aboubakr Elnashar

Advantages

No anesthesia

Complications fewest 108

most effective intervention

decrease the need for additional interventions

provides a higher concentration of the

embryocide locally

avoidance of systemic side effects

more rapid interruption of the pregnancy

Aboubakr Elnashar

Aspiration of gestational sac fluid injection of methotrexate in the sac injection of homeostatic agent and pituitrin in the uterine muscle layer and injection of triple anti-inflammatory drugs around the uterus in 12 patients with CSP (Kong et al 2014)

Ultrasonography-guided multidrug interventional therapy for CSP is a new safe effective minimally invasive method

2 Use of a Foley balloon catheter

Indications

1 Alone (usually in gestations of 5ndash7 w) in the

hope of stopping the evolution of the pregnancy

by placing pressure on a small GS

2 In conjunction with another tt

3 Backup if bleeding occurs

French-12 size 10-mL silicone balloon catheter or French-14 catheter with a 30-mL balloon

balloon inflated with 5

mL of saline

TV power Doppler image

of the inflated balloon

(B) in a case of a CSP at

6 w 4 days after

injection of MXT

Aboubakr Elnashar

Steps GA not required TAS guidance Or TVS guidance allow for more precise placement and assess the pressure avoiding over inflation of the balloon Catheter is kept 24 to 48 h with the outer end of the catheter fastened to the patientrsquos thigh Antibiotics Reevaluate after 48H Aboubakr Elnashar

3 UAE alone or in combination Indication 1 As a rescue procedure in the case of significant

bleeding or an A-VM 2 Concurrent with MTH Not as a primary tt delay between tt and effect allows the gestation to

grow and vascularity to increase Disadvantages 1 GA 2 Complication rate 47 3 Not the best 1st -line tt

Aboubakr Elnashar

Surgical excision

laparoscopy or laparotomy may be best tt

No response to conservative medical tt

Patient late to present

Allows for revision of the CS scar with new uterine closure that may minimize risk of recurrence Risks postoperative adhesions impair future fertility increased size of surgical wounds longer hospital stay and recovery increased risk of future placenta previaaccreta

Aboubakr Elnashar

Aboubakr Elnashar

1 Excision by laparotomy alone or in combination with hysteroscopy

18 cases 5 complications and only when used in an emergency situation

Aboubakr Elnashar

2 Laparoscopic excision Complication rate 306 Laparoscopy combined with hysteroscopy Complication rate 20

Aboubakr Elnashar

3 Hysteroscopy alone or in combination complication rate 138 Hysteroscopy combined with TA US guidance 9 cases no complications reasonable operative solution Hysteroscopy combined with mifepristone complication rate17

Aboubakr Elnashar

4 Suction aspiration or DampC alone or in

combination

Isolated D amp C should be avoided

1 Trophoblastic tissue and villi are implanted

within the myometrium D ampC is unlikely to expel

the GS without rupturing the uterine wall or

damaging the bladder

2 massive bleeding emergency laparotomies

loss of the uterus

3 exposed vessels in the cervical scar tissue bleed no muscle grid to contract and contain the profuse bleeding

4 Complication rate 62 (29ndash86)

bleeding complications necessitating 3rd -line tt that almost always was surgical Aboubakr Elnashar

MTX followed by suction curettage Mean blood loss 707 mL (100ndash2000 mL) tt failure 3 out of 45 despite insertion of a Foley balloon catheter If DampC is still the preferred tt of choice blood products should be available balloon catheter should be inserted in the cervix

Preoperative determination of CSP implantation depth and extent is important in selecting candidates for surgical treatment Primary single-step surgical evacuation was successful in most patients with superficial implantation but patients should be informed of the possibility of salvage interventions before undergoing surgical evacuation (Kong et

al 2014)

Aboubakr Elnashar

FOLLOW-UP Placenta is implanted mostly within fibrous

tissue absorption of the GS is slow after med tt

1 9 w to obtain clearance of βHCG

2 3 months for clearance of GS on TVS

1 βHCG weekly until it is undetectable

2 TVS Monthly to evaluate the size of retained

products of conception

Aboubakr Elnashar

3 SIS in a nonpregnant patient uterine wall integrity size of the cesarean scar which may relate to the possibility of uterine scar complications in future pregnancies 4 Early TVS After CSP After CS to confirm an intrauterine location of the new gestation

Aboubakr Elnashar

5 Avoiding pregnancy No guidelines 12 to 24 months 6 Repair of scar before future pregnancies not known whether required or not Severely deficient uterine scars 10 of women who have had prior CS but CSP are much more rare

Aboubakr Elnashar

Outcomes Uneventful viable pregnancies have been reported after all modalities of conservative management Recurrence rate 5 IU pregnancy 95 spontaneous pregnancy 88 Normal pregnancy 65 Spontaneous abortion 35 higher than expected

Aboubakr Elnashar

4 PREVENTION OF CSP

1 Surgical repair of the uterine dehiscence (niche) in patients with previous CS while not pregnant

Ben Nagi et al reported on a successful surgical repair Donnez et al hysteroscopic repair Klemm et al laparoscopic-assisted vaginal repair Yalcinkaya et al robotic-assisted laparoscopic repair More research is necessary before making recommendations for such surgical tt to prevent CSP

Aboubakr Elnashar

2 Specific surgical technique single- or double-layer closure of the incision can minimize or avoid a CSP

Aboubakr Elnashar

SUMMARY CSP

An uncommon but potentially life-threatening

The incidence is rising as CSR is rising

Precursor of morbidly adherent placenta

Do not confuse CSP with ectopic pregnancy

Early diagnosis is important TVS is the most

effective and preferred diagnostic tool

A key first step Determine whether heart activity is

present

Aboubakr Elnashar

If heart activity is documented Counsel the patient

inform the patient of the risks of pregnancy

continuation

If continuation an additional counseling session

risks

If termination a reliable tt that stops fetal heart beat

without delay

Avoid single tts unlikely to be effective

DampC

suction curettage

single-dose IM MTX and

UAE

Aboubakr Elnashar

Consider combination treatments best results

direct injection of MTX or Kcl into GS with TVS

guidance

Keep a catheter at hand

At the time of discharging after a CS in a future

pregnancy an early visit for TVS is important

4 PREVENTION OF CSP

1 Surgical repair of the uterine dehiscence (niche) in patients with previous CS while not pregnant

Ben Nagi et al reported on a successful surgical repair Donnez et al hysteroscopic repair Klemm et al laparoscopic-assisted vaginal repair Yalcinkaya et al robotic-assisted laparoscopic repair More research is necessary before making recommendations for such surgical tt to prevent CSP

Aboubakr Elnashar

2 Specific surgical technique single- or double-layer closure of the incision can minimize or avoid a CSP

Aboubakr Elnashar

SUMMARY CSP

An uncommon but potentially life-threatening

The incidence is rising as CSR is rising

Precursor of morbidly adherent placenta

Do not confuse CSP with ectopic pregnancy

Early diagnosis is important TVS is the most

effective and preferred diagnostic tool

A key first step Determine whether heart activity is

present

Aboubakr Elnashar

If heart activity is documented Counsel the patient

inform the patient of the risks of pregnancy

continuation

If continuation an additional counseling session

risks

If termination a reliable tt that stops fetal heart beat

without delay

Avoid single tts unlikely to be effective

DampC

suction curettage

single-dose IM MTX and

UAE

Aboubakr Elnashar

Consider combination treatments best results

direct injection of MTX or Kcl into GS with TVS

guidance

Keep a catheter at hand

At the time of discharging after a CS in a future

pregnancy an early visit for TVS is important

Abstract

Heterotopic cesarean scar pregnancy is a rare life-threatening form of

ectopic pregnancy To provide information regarding the clinical

manifestations diagnosis management and prognosis of this condition

we reviewed all cases reported in the English literature All literature on

heterotopic cesarean scar pregnancy was retrieved by searching the

PubMed database and tracking references of the relevant literature Full

texts were reviewed and clinical manifestations diagnostic methods and

the relationship between the treatment and prognosis were summarized A

total of 14 patients with heterotopic cesarean scar pregnancies were

identified including 6 spontaneous pregnancies and 8 following in vitro

fertilization-embryo transfer Gestational ages at diagnosis ranged from 5

weeks to 8 weeks 4 days Only 5 cases presented with vaginal bleeding

and the others were asymptomatic All 14 cases were diagnosed by

transvaginal sonography One patient with no future fertility requirements

underwent pregnancy termination by methotrexate Of the remaining 13

patients who desired to preserve their intrauterine gestations 10 were

treated by sonographically guided selective embryo reduction in situ (by

2 Number of children

3 Number of previous CS

4 Anterior uterine wall thickness

uterine space Non surgical tt

5 Expertise of the clinicians

Aboubakr Elnashar

Gynecologic surgeons laparoscopy and hysteroscopy or laparotomy Obstetricians radiologists and IVF specialists IM MTX or US local MTX (or Kcl) UAE occasionally

Aboubakr Elnashar

Counseling of the patient

Immediate and decisive action to prevent further

growth of the embryo or fetus

Options

1 Continuation of the pregnancy

Successful births

uneventful term pregnancy poor

Hysterectomy rate 71

increased risk of placenta previaaccreta and

massive hge

Aboubakr Elnashar

2 Termination of the pregnancy in 1st T

Substantial hge 20-40

Hysterectomy substantially lower

Termination Recommended particularly when

Early evidence of progression toward the abdominal

cavity or bladder

increased risk of life-threatening complications and

loss of fertility

Aboubakr Elnashar

Potential complications

751 cases reviewed 218 resulted in major surgery or interventional

radiology procedures (primary or emergency) The total planned primary (nonemergency) interventions performed were 66 (87) which included 3 hysterectomies 14 laparotomies and 49 uterine artery embolizations or ligations There were 98 (130) emergency interventions which included 36 hysterectomies 40 laparotomies and 22 uterine artery embolizations or ligations (Timor-Tritsch et al 2014)

(Immediate or delayed) Need secondary tt for blood loss ge200 mL or blood transfusion Complications are most often when the following

tt used alone

lowest complication rate

1 Local and US directed MTX injection with or

without additional IM MTX

2 Surgical excision by hysteroscopic guidance

Aboubakr Elnashar

Management approaches I Surgical Excision Laparotomy or Hysterectomy or Laparoscopic or Hysteroscopic followed by DampC II Minimally invasive local injection of MTX or Kcl or UAE in combination with IM MTX Medical tt alone not recommended

Aboubakr Elnashar

Medical 1 Systemic single-dose MTX 1 mgkg or 50 mgm2 of body surface area complication rate 646 second tt when the fetal heart beat did not cease after several days

High failure rate slow action and questionable ability to stop cardiac activity and placental expansion The expected result can take days and all the while GS the embryo or fetus and its vascularity are growing Secondary tt has to address a larger gestation with more abundant vascularization

Aboubakr Elnashar

Systemic MTX as a single tt should be avoided 1 Waiting days for its effect to stop the heart beats which may not happen 2 It also led to the additional growth of the embryofetus as well as the vascularization of GS 3 Wastes precious time

Aboubakr Elnashar

2 Systemic multidose sequential MTX Two to three IM (1 mgkg BW or 50 mgmm2 of surface area) at an interval of 2 or 3 days over the course of a week

Cumulative adverse effects on the liver and bone marrow Success rate 75 Hysterectomy 6 Best results βHCG le 5000 mUmL Fibrous tissue within the scar around GS can delay systemic MTX absorption into GS Aboubakr Elnashar

Approach

TV approach is favored over TA

1 better visualization of the needle 2 shorter distance to reach the sac 3 decreased risk of bladder injury TAS guidance slighter higher complication rate (15) than those

using TVS guidance

Aboubakr Elnashar

Steps

1 After confirming the placement of needle 25 mg

of MTX in 1 mL of solution is injected slowly in

the GS

2 25 mg is injected outside GS as the needle is

withdrawn preferably the placental site

3 TVS 60-90 m after the procedure confirm

cessation of FH and to identify local bleeding

4 IM of 25 mg MTX (for a total combined dose of

75 mg) before discharge from our unit

5 24-48 h follow-up scan Close monitoring

Management approaches I Surgical Excision Laparotomy or Hysterectomy or Laparoscopic or Hysteroscopic followed by DampC II Minimally invasive local injection of MTX or Kcl or UAE in combination with IM MTX Medical tt alone not recommended

Aboubakr Elnashar

Medical 1 Systemic single-dose MTX 1 mgkg or 50 mgm2 of body surface area complication rate 646 second tt when the fetal heart beat did not cease after several days

High failure rate slow action and questionable ability to stop cardiac activity and placental expansion The expected result can take days and all the while GS the embryo or fetus and its vascularity are growing Secondary tt has to address a larger gestation with more abundant vascularization

Aboubakr Elnashar

Systemic MTX as a single tt should be avoided 1 Waiting days for its effect to stop the heart beats which may not happen 2 It also led to the additional growth of the embryofetus as well as the vascularization of GS 3 Wastes precious time

Aboubakr Elnashar

2 Systemic multidose sequential MTX Two to three IM (1 mgkg BW or 50 mgmm2 of surface area) at an interval of 2 or 3 days over the course of a week

Steps

1 After confirming the placement of needle 25 mg

of MTX in 1 mL of solution is injected slowly in

the GS

2 25 mg is injected outside GS as the needle is

withdrawn preferably the placental site

MTX followed by suction curettage Mean blood loss 707 mL (100ndash2000 mL) tt failure 3 out of 45 despite insertion of a Foley balloon catheter If DampC is still the preferred tt of choice blood products should be available balloon catheter should be inserted in the cervix

Preoperative determination of CSP implantation depth and extent is important in selecting candidates for surgical treatment Primary single-step surgical evacuation was successful in most patients with superficial implantation but patients should be informed of the possibility of salvage interventions before undergoing surgical evacuation (Kong et

al 2014)

Aboubakr Elnashar

FOLLOW-UP Placenta is implanted mostly within fibrous

tissue absorption of the GS is slow after med tt

1 9 w to obtain clearance of βHCG

2 3 months for clearance of GS on TVS

2 TVS Monthly to evaluate the size of retained

products of conception

Aboubakr Elnashar

3 SIS in a nonpregnant patient uterine wall integrity size of the cesarean scar which may relate to the possibility of uterine scar complications in future pregnancies 4 Early TVS After CSP After CS to confirm an intrauterine location of the new gestation

5 Avoiding pregnancy No guidelines 12 to 24 months 6 Repair of scar before future pregnancies not known whether required or not Severely deficient uterine scars 10 of women who have had prior CS but CSP are much more rare

Aboubakr Elnashar

Outcomes Uneventful viable pregnancies have been reported after all modalities of conservative management Recurrence rate 5 IU pregnancy 95 spontaneous pregnancy 88 Normal pregnancy 65 Spontaneous abortion 35 higher than expected

Aboubakr Elnashar

4 PREVENTION OF CSP

1 Surgical repair of the uterine dehiscence (niche) in patients with previous CS while not pregnant

Ben Nagi et al reported on a successful surgical repair Donnez et al hysteroscopic repair Klemm et al laparoscopic-assisted vaginal repair Yalcinkaya et al robotic-assisted laparoscopic repair More research is necessary before making recommendations for such surgical tt to prevent CSP

Aboubakr Elnashar

2 Specific surgical technique single- or double-layer closure of the incision can minimize or avoid a CSP

Aboubakr Elnashar

SUMMARY CSP

An uncommon but potentially life-threatening

The incidence is rising as CSR is rising

Precursor of morbidly adherent placenta

Do not confuse CSP with ectopic pregnancy

Early diagnosis is important TVS is the most

effective and preferred diagnostic tool

A key first step Determine whether heart activity is

present

Aboubakr Elnashar

If heart activity is documented Counsel the patient

inform the patient of the risks of pregnancy

continuation

If continuation an additional counseling session

risks

If termination a reliable tt that stops fetal heart beat

without delay

Avoid single tts unlikely to be effective

DampC

suction curettage

single-dose IM MTX and

UAE

Aboubakr Elnashar

Consider combination treatments best results

direct injection of MTX or Kcl into GS with TVS

guidance

Keep a catheter at hand

At the time of discharging after a CS in a future

pregnancy an early visit for TVS is important

Abstract

Heterotopic cesarean scar pregnancy is a rare life-threatening form of

ectopic pregnancy To provide information regarding the clinical

manifestations diagnosis management and prognosis of this condition

we reviewed all cases reported in the English literature All literature on

heterotopic cesarean scar pregnancy was retrieved by searching the

PubMed database and tracking references of the relevant literature Full

texts were reviewed and clinical manifestations diagnostic methods and

the relationship between the treatment and prognosis were summarized A

total of 14 patients with heterotopic cesarean scar pregnancies were

identified including 6 spontaneous pregnancies and 8 following in vitro

fertilization-embryo transfer Gestational ages at diagnosis ranged from 5

weeks to 8 weeks 4 days Only 5 cases presented with vaginal bleeding

and the others were asymptomatic All 14 cases were diagnosed by

transvaginal sonography One patient with no future fertility requirements

underwent pregnancy termination by methotrexate Of the remaining 13

patients who desired to preserve their intrauterine gestations 10 were

treated by sonographically guided selective embryo reduction in situ (by

Abstract

OBJECTIVE

To assess the efficacy and safety of primary surgical evacuation therapy

for cesarean scarpregnancy (CSP) of the first trimester and to evaluate its

possible prognostic factors

DESIGN

Retrospective consecutive cohort study

SETTING

Tertiary care university hospital

SUBJECT(S)

A cohort of patients with CSP and clear ultrasound images who underwent

primary surgical evacuation from January 2000 to December 2012

INTERVENTION(S)

Patients fulfilling the ultrasound criteria of CSP were further classified into

superficial and deep groups according to their implantation locations and

extents The final decision on the method of treatment including

methotrexate chemotherapy surgical evacuation and others was made by

the patients after consultation with the physician Pretreatment patient

III For treatment of CSP all are correct

except

1Anterior uterine wall thickness is important

2With pregnancy continuation hysterectomy

rate is 17

3Termination of the pregnancy in first

trimester is recommended

4Immediate and decisive action is

recommended

Aboubakr Elnashar

IV All are correct regarding CSP treatment

except

1 Complications are most often when single

IM Methotrexate or DampC

2 Complications are at lowest rate with

Local and US directed MTX injection with

or without additional IM MTX

3 Use of a Foley balloon catheter is not

recommended

4 laparoscopy or laparotomy with excision

of the pregnancy may be best treatment

Aboubakr Elnashar

Counseling of the patient

Immediate and decisive action to prevent further

growth of the embryo or fetus

Options

1 Continuation of the pregnancy

Successful births

uneventful term pregnancy poor

Hysterectomy rate 71

increased risk of placenta previaaccreta and

massive hge

Aboubakr Elnashar

2 Termination of the pregnancy in 1st T

Substantial hge 20-40

Hysterectomy substantially lower

Termination Recommended particularly when

Early evidence of progression toward the abdominal

cavity or bladder

increased risk of life-threatening complications and

loss of fertility

Aboubakr Elnashar

Potential complications

751 cases reviewed 218 resulted in major surgery or interventional

radiology procedures (primary or emergency) The total planned primary (nonemergency) interventions performed were 66 (87) which included 3 hysterectomies 14 laparotomies and 49 uterine artery embolizations or ligations There were 98 (130) emergency interventions which included 36 hysterectomies 40 laparotomies and 22 uterine artery embolizations or ligations (Timor-Tritsch et al 2014)

(Immediate or delayed) Need secondary tt for blood loss ge200 mL or blood transfusion Complications are most often when the following

Management approaches I Surgical Excision Laparotomy or Hysterectomy or Laparoscopic or Hysteroscopic followed by DampC II Minimally invasive local injection of MTX or Kcl or UAE in combination with IM MTX Medical tt alone not recommended

Aboubakr Elnashar

Medical 1 Systemic single-dose MTX 1 mgkg or 50 mgm2 of body surface area complication rate 646 second tt when the fetal heart beat did not cease after several days

High failure rate slow action and questionable ability to stop cardiac activity and placental expansion The expected result can take days and all the while GS the embryo or fetus and its vascularity are growing Secondary tt has to address a larger gestation with more abundant vascularization

Aboubakr Elnashar

Systemic MTX as a single tt should be avoided 1 Waiting days for its effect to stop the heart beats which may not happen 2 It also led to the additional growth of the embryofetus as well as the vascularization of GS 3 Wastes precious time

Aboubakr Elnashar

2 Systemic multidose sequential MTX Two to three IM (1 mgkg BW or 50 mgmm2 of surface area) at an interval of 2 or 3 days over the course of a week

Potential complications

751 cases reviewed 218 resulted in major surgery or interventional

radiology procedures (primary or emergency) The total planned primary (nonemergency) interventions performed were 66 (87) which included 3 hysterectomies 14 laparotomies and 49 uterine artery embolizations or ligations There were 98 (130) emergency interventions which included 36 hysterectomies 40 laparotomies and 22 uterine artery embolizations or ligations (Timor-Tritsch et al 2014)

(Immediate or delayed) Need secondary tt for blood loss ge200 mL or blood transfusion Complications are most often when the following

2 Surgical excision by hysteroscopic guidance

Aboubakr Elnashar

Management approaches I Surgical Excision Laparotomy or Hysterectomy or Laparoscopic or Hysteroscopic followed by DampC II Minimally invasive local injection of MTX or Kcl or UAE in combination with IM MTX Medical tt alone not recommended

Aboubakr Elnashar

Medical 1 Systemic single-dose MTX 1 mgkg or 50 mgm2 of body surface area complication rate 646 second tt when the fetal heart beat did not cease after several days

High failure rate slow action and questionable ability to stop cardiac activity and placental expansion The expected result can take days and all the while GS the embryo or fetus and its vascularity are growing Secondary tt has to address a larger gestation with more abundant vascularization

Aboubakr Elnashar

Systemic MTX as a single tt should be avoided 1 Waiting days for its effect to stop the heart beats which may not happen 2 It also led to the additional growth of the embryofetus as well as the vascularization of GS 3 Wastes precious time

Aboubakr Elnashar

2 Systemic multidose sequential MTX Two to three IM (1 mgkg BW or 50 mgmm2 of surface area) at an interval of 2 or 3 days over the course of a week

Cumulative adverse effects on the liver and bone marrow Success rate 75 Hysterectomy 6 Best results βHCG le 5000 mUmL Fibrous tissue within the scar around GS can delay systemic MTX absorption into GS Aboubakr Elnashar

Minimally invasive

with US guidance

Indications

hemodynamically stable

unruptured CSP

le8w gestation

myometrial thickness between GS and bladder

Aboubakr Elnashar

Approach

TV approach is favored over TA

1 better visualization of the needle 2 shorter distance to reach the sac 3 decreased risk of bladder injury TAS guidance slighter higher complication rate (15) than those

using TVS guidance

Aboubakr Elnashar

Steps

1 After confirming the placement of needle 25 mg

of MTX in 1 mL of solution is injected slowly in

the GS

2 25 mg is injected outside GS as the needle is

withdrawn preferably the placental site

3 TVS 60-90 m after the procedure confirm

cessation of FH and to identify local bleeding

4 IM of 25 mg MTX (for a total combined dose of

75 mg) before discharge from our unit

5 24-48 h follow-up scan Close monitoring

hge may still occur

Advantages

No anesthesia

most effective intervention

decrease the need for additional interventions

embryocide locally

avoidance of systemic side effects

more rapid interruption of the pregnancy

Aboubakr Elnashar

Aspiration of gestational sac fluid injection of methotrexate in the sac injection of homeostatic agent and pituitrin in the uterine muscle layer and injection of triple anti-inflammatory drugs around the uterus in 12 patients with CSP (Kong et al 2014)

Ultrasonography-guided multidrug interventional therapy for CSP is a new safe effective minimally invasive method

2 Use of a Foley balloon catheter

Indications

1 Alone (usually in gestations of 5ndash7 w) in the

hope of stopping the evolution of the pregnancy

by placing pressure on a small GS

2 In conjunction with another tt

3 Backup if bleeding occurs

French-12 size 10-mL silicone balloon catheter or French-14 catheter with a 30-mL balloon

Aboubakr Elnashar

Steps GA not required TAS guidance Or TVS guidance allow for more precise placement and assess the pressure avoiding over inflation of the balloon Catheter is kept 24 to 48 h with the outer end of the catheter fastened to the patientrsquos thigh Antibiotics Reevaluate after 48H Aboubakr Elnashar

3 UAE alone or in combination Indication 1 As a rescue procedure in the case of significant

bleeding or an A-VM 2 Concurrent with MTH Not as a primary tt delay between tt and effect allows the gestation to

grow and vascularity to increase Disadvantages 1 GA 2 Complication rate 47 3 Not the best 1st -line tt

Aboubakr Elnashar

Surgical excision

laparoscopy or laparotomy may be best tt

No response to conservative medical tt

Patient late to present

Allows for revision of the CS scar with new uterine closure that may minimize risk of recurrence Risks postoperative adhesions impair future fertility increased size of surgical wounds longer hospital stay and recovery increased risk of future placenta previaaccreta

Aboubakr Elnashar

Aboubakr Elnashar

1 Excision by laparotomy alone or in combination with hysteroscopy

18 cases 5 complications and only when used in an emergency situation

Aboubakr Elnashar

2 Laparoscopic excision Complication rate 306 Laparoscopy combined with hysteroscopy Complication rate 20

Aboubakr Elnashar

3 Hysteroscopy alone or in combination complication rate 138 Hysteroscopy combined with TA US guidance 9 cases no complications reasonable operative solution Hysteroscopy combined with mifepristone complication rate17

Aboubakr Elnashar

4 Suction aspiration or DampC alone or in

combination

Isolated D amp C should be avoided

1 Trophoblastic tissue and villi are implanted

within the myometrium D ampC is unlikely to expel

the GS without rupturing the uterine wall or

damaging the bladder

2 massive bleeding emergency laparotomies

loss of the uterus

3 exposed vessels in the cervical scar tissue bleed no muscle grid to contract and contain the profuse bleeding

4 Complication rate 62 (29ndash86)

bleeding complications necessitating 3rd -line tt that almost always was surgical Aboubakr Elnashar

MTX followed by suction curettage Mean blood loss 707 mL (100ndash2000 mL) tt failure 3 out of 45 despite insertion of a Foley balloon catheter If DampC is still the preferred tt of choice blood products should be available balloon catheter should be inserted in the cervix

Preoperative determination of CSP implantation depth and extent is important in selecting candidates for surgical treatment Primary single-step surgical evacuation was successful in most patients with superficial implantation but patients should be informed of the possibility of salvage interventions before undergoing surgical evacuation (Kong et

al 2014)

Aboubakr Elnashar

FOLLOW-UP Placenta is implanted mostly within fibrous

tissue absorption of the GS is slow after med tt

1 9 w to obtain clearance of βHCG

2 3 months for clearance of GS on TVS

1 βHCG weekly until it is undetectable

2 TVS Monthly to evaluate the size of retained

products of conception

Aboubakr Elnashar

3 SIS in a nonpregnant patient uterine wall integrity size of the cesarean scar which may relate to the possibility of uterine scar complications in future pregnancies 4 Early TVS After CSP After CS to confirm an intrauterine location of the new gestation

Aboubakr Elnashar

5 Avoiding pregnancy No guidelines 12 to 24 months 6 Repair of scar before future pregnancies not known whether required or not Severely deficient uterine scars 10 of women who have had prior CS but CSP are much more rare

Aboubakr Elnashar

Outcomes Uneventful viable pregnancies have been reported after all modalities of conservative management Recurrence rate 5 IU pregnancy 95 spontaneous pregnancy 88 Normal pregnancy 65 Spontaneous abortion 35 higher than expected

Aboubakr Elnashar

4 PREVENTION OF CSP

1 Surgical repair of the uterine dehiscence (niche) in patients with previous CS while not pregnant

Ben Nagi et al reported on a successful surgical repair Donnez et al hysteroscopic repair Klemm et al laparoscopic-assisted vaginal repair Yalcinkaya et al robotic-assisted laparoscopic repair More research is necessary before making recommendations for such surgical tt to prevent CSP

Aboubakr Elnashar

2 Specific surgical technique single- or double-layer closure of the incision can minimize or avoid a CSP

Aboubakr Elnashar

SUMMARY CSP

An uncommon but potentially life-threatening

The incidence is rising as CSR is rising

Precursor of morbidly adherent placenta

Do not confuse CSP with ectopic pregnancy

Early diagnosis is important TVS is the most

effective and preferred diagnostic tool

A key first step Determine whether heart activity is

present

Aboubakr Elnashar

If heart activity is documented Counsel the patient

inform the patient of the risks of pregnancy

continuation

If continuation an additional counseling session

risks

If termination a reliable tt that stops fetal heart beat

without delay

Avoid single tts unlikely to be effective

DampC

suction curettage

single-dose IM MTX and

UAE

Aboubakr Elnashar

Consider combination treatments best results

direct injection of MTX or Kcl into GS with TVS

guidance

Keep a catheter at hand

At the time of discharging after a CS in a future

pregnancy an early visit for TVS is important

Abstract

Heterotopic cesarean scar pregnancy is a rare life-threatening form of

ectopic pregnancy To provide information regarding the clinical

manifestations diagnosis management and prognosis of this condition

we reviewed all cases reported in the English literature All literature on

heterotopic cesarean scar pregnancy was retrieved by searching the

PubMed database and tracking references of the relevant literature Full

texts were reviewed and clinical manifestations diagnostic methods and

the relationship between the treatment and prognosis were summarized A

total of 14 patients with heterotopic cesarean scar pregnancies were

identified including 6 spontaneous pregnancies and 8 following in vitro

fertilization-embryo transfer Gestational ages at diagnosis ranged from 5

weeks to 8 weeks 4 days Only 5 cases presented with vaginal bleeding

and the others were asymptomatic All 14 cases were diagnosed by

transvaginal sonography One patient with no future fertility requirements

underwent pregnancy termination by methotrexate Of the remaining 13

patients who desired to preserve their intrauterine gestations 10 were

treated by sonographically guided selective embryo reduction in situ (by

FOLLOW-UP Placenta is implanted mostly within fibrous

tissue absorption of the GS is slow after med tt

1 9 w to obtain clearance of βHCG

Outcomes Uneventful viable pregnancies have been reported after all modalities of conservative management Recurrence rate 5 IU pregnancy 95 spontaneous pregnancy 88 Normal pregnancy 65 Spontaneous abortion 35 higher than expected

Aboubakr Elnashar

4 PREVENTION OF CSP

1 Surgical repair of the uterine dehiscence (niche) in patients with previous CS while not pregnant

Ben Nagi et al reported on a successful surgical repair Donnez et al hysteroscopic repair Klemm et al laparoscopic-assisted vaginal repair Yalcinkaya et al robotic-assisted laparoscopic repair More research is necessary before making recommendations for such surgical tt to prevent CSP

Aboubakr Elnashar

2 Specific surgical technique single- or double-layer closure of the incision can minimize or avoid a CSP

Aboubakr Elnashar

SUMMARY CSP

An uncommon but potentially life-threatening

The incidence is rising as CSR is rising

Precursor of morbidly adherent placenta

Do not confuse CSP with ectopic pregnancy

Early diagnosis is important TVS is the most

effective and preferred diagnostic tool

A key first step Determine whether heart activity is

present

Aboubakr Elnashar

If heart activity is documented Counsel the patient

inform the patient of the risks of pregnancy

continuation

If continuation an additional counseling session

risks

If termination a reliable tt that stops fetal heart beat

without delay

Avoid single tts unlikely to be effective

DampC

suction curettage

single-dose IM MTX and

UAE

Aboubakr Elnashar

Consider combination treatments best results

direct injection of MTX or Kcl into GS with TVS

guidance

Keep a catheter at hand

At the time of discharging after a CS in a future

pregnancy an early visit for TVS is important

least or no complications

Aboubakr Elnashar

Timor-Tritsch et al 2014 Aboubakr Elnashar

Treatment should be individualized based on

1 Patientrsquos age

2 Number of children

3 Number of previous CS

4 Anterior uterine wall thickness

uterine space Non surgical tt

5 Expertise of the clinicians

Aboubakr Elnashar

Gynecologic surgeons laparoscopy and hysteroscopy or laparotomy Obstetricians radiologists and IVF specialists IM MTX or US local MTX (or Kcl) UAE occasionally

Aboubakr Elnashar

Counseling of the patient

Immediate and decisive action to prevent further

growth of the embryo or fetus

Options

1 Continuation of the pregnancy

Successful births

uneventful term pregnancy poor

Hysterectomy rate 71

increased risk of placenta previaaccreta and

massive hge

Aboubakr Elnashar

2 Termination of the pregnancy in 1st T

Substantial hge 20-40

Hysterectomy substantially lower

Termination Recommended particularly when

Early evidence of progression toward the abdominal

cavity or bladder

increased risk of life-threatening complications and

loss of fertility

Aboubakr Elnashar

Potential complications

751 cases reviewed 218 resulted in major surgery or interventional

radiology procedures (primary or emergency) The total planned primary (nonemergency) interventions performed were 66 (87) which included 3 hysterectomies 14 laparotomies and 49 uterine artery embolizations or ligations There were 98 (130) emergency interventions which included 36 hysterectomies 40 laparotomies and 22 uterine artery embolizations or ligations (Timor-Tritsch et al 2014)

(Immediate or delayed) Need secondary tt for blood loss ge200 mL or blood transfusion Complications are most often when the following

lowest complication rate

1 Local and US directed MTX injection with or

without additional IM MTX

2 Surgical excision by hysteroscopic guidance

Aboubakr Elnashar

Management approaches I Surgical Excision Laparotomy or Hysterectomy or Laparoscopic or Hysteroscopic followed by DampC II Minimally invasive local injection of MTX or Kcl or UAE in combination with IM MTX Medical tt alone not recommended

Aboubakr Elnashar

Medical 1 Systemic single-dose MTX 1 mgkg or 50 mgm2 of body surface area complication rate 646 second tt when the fetal heart beat did not cease after several days

High failure rate slow action and questionable ability to stop cardiac activity and placental expansion The expected result can take days and all the while GS the embryo or fetus and its vascularity are growing Secondary tt has to address a larger gestation with more abundant vascularization

Aboubakr Elnashar

Systemic MTX as a single tt should be avoided 1 Waiting days for its effect to stop the heart beats which may not happen 2 It also led to the additional growth of the embryofetus as well as the vascularization of GS 3 Wastes precious time

Aboubakr Elnashar

2 Systemic multidose sequential MTX Two to three IM (1 mgkg BW or 50 mgmm2 of surface area) at an interval of 2 or 3 days over the course of a week

Cumulative adverse effects on the liver and bone marrow Success rate 75 Hysterectomy 6 Best results βHCG le 5000 mUmL Fibrous tissue within the scar around GS can delay systemic MTX absorption into GS Aboubakr Elnashar

Approach

TV approach is favored over TA

1 better visualization of the needle 2 shorter distance to reach the sac 3 decreased risk of bladder injury TAS guidance slighter higher complication rate (15) than those

using TVS guidance

Aboubakr Elnashar

Steps

1 After confirming the placement of needle 25 mg

of MTX in 1 mL of solution is injected slowly in

the GS

2 25 mg is injected outside GS as the needle is

withdrawn preferably the placental site

3 TVS 60-90 m after the procedure confirm

cessation of FH and to identify local bleeding

4 IM of 25 mg MTX (for a total combined dose of

75 mg) before discharge from our unit

4 PREVENTION OF CSP

1 Surgical repair of the uterine dehiscence (niche) in patients with previous CS while not pregnant

Ben Nagi et al reported on a successful surgical repair Donnez et al hysteroscopic repair Klemm et al laparoscopic-assisted vaginal repair Yalcinkaya et al robotic-assisted laparoscopic repair More research is necessary before making recommendations for such surgical tt to prevent CSP

Aboubakr Elnashar

2 Specific surgical technique single- or double-layer closure of the incision can minimize or avoid a CSP

Aboubakr Elnashar

SUMMARY CSP

An uncommon but potentially life-threatening

The incidence is rising as CSR is rising

Precursor of morbidly adherent placenta

Do not confuse CSP with ectopic pregnancy

Early diagnosis is important TVS is the most

effective and preferred diagnostic tool

A key first step Determine whether heart activity is

present

Aboubakr Elnashar

If heart activity is documented Counsel the patient

inform the patient of the risks of pregnancy

continuation

If continuation an additional counseling session

risks

If termination a reliable tt that stops fetal heart beat

without delay

Avoid single tts unlikely to be effective

DampC

suction curettage

single-dose IM MTX and

UAE

Aboubakr Elnashar

Consider combination treatments best results

direct injection of MTX or Kcl into GS with TVS

guidance

Keep a catheter at hand

At the time of discharging after a CS in a future

pregnancy an early visit for TVS is important

Abstract

Heterotopic cesarean scar pregnancy is a rare life-threatening form of

ectopic pregnancy To provide information regarding the clinical

manifestations diagnosis management and prognosis of this condition

we reviewed all cases reported in the English literature All literature on

heterotopic cesarean scar pregnancy was retrieved by searching the

PubMed database and tracking references of the relevant literature Full

texts were reviewed and clinical manifestations diagnostic methods and

the relationship between the treatment and prognosis were summarized A

total of 14 patients with heterotopic cesarean scar pregnancies were

identified including 6 spontaneous pregnancies and 8 following in vitro

fertilization-embryo transfer Gestational ages at diagnosis ranged from 5

weeks to 8 weeks 4 days Only 5 cases presented with vaginal bleeding

and the others were asymptomatic All 14 cases were diagnosed by

transvaginal sonography One patient with no future fertility requirements

underwent pregnancy termination by methotrexate Of the remaining 13

patients who desired to preserve their intrauterine gestations 10 were

treated by sonographically guided selective embryo reduction in situ (by

SUMMARY CSP

An uncommon but potentially life-threatening

The incidence is rising as CSR is rising

Precursor of morbidly adherent placenta

Do not confuse CSP with ectopic pregnancy

Early diagnosis is important TVS is the most

effective and preferred diagnostic tool

A key first step Determine whether heart activity is

present

Aboubakr Elnashar

If heart activity is documented Counsel the patient

inform the patient of the risks of pregnancy

continuation

If continuation an additional counseling session

risks

If termination a reliable tt that stops fetal heart beat

without delay

Avoid single tts unlikely to be effective

DampC

suction curettage

single-dose IM MTX and

UAE

Aboubakr Elnashar

Consider combination treatments best results

direct injection of MTX or Kcl into GS with TVS

guidance

Keep a catheter at hand

At the time of discharging after a CS in a future

pregnancy an early visit for TVS is important

eliminating GS

preserving fertility

No universal tt guidelines

No clear conclusion

most effective

least or no complications

Aboubakr Elnashar

Timor-Tritsch et al 2014 Aboubakr Elnashar

Treatment should be individualized based on

1 Patientrsquos age

2 Number of children

3 Number of previous CS

4 Anterior uterine wall thickness

when the trophoblast reaches the bladder-

uterine space Non surgical tt

5 Expertise of the clinicians

Aboubakr Elnashar

Gynecologic surgeons laparoscopy and hysteroscopy or laparotomy Obstetricians radiologists and IVF specialists IM MTX or US local MTX (or Kcl) UAE occasionally

Aboubakr Elnashar

Counseling of the patient

Immediate and decisive action to prevent further

growth of the embryo or fetus

Options

1 Continuation of the pregnancy

Successful births

uneventful term pregnancy poor

Hysterectomy rate 71

increased risk of placenta previaaccreta and

massive hge

Aboubakr Elnashar

2 Termination of the pregnancy in 1st T

Substantial hge 20-40

Hysterectomy substantially lower

Termination Recommended particularly when

Early evidence of progression toward the abdominal

cavity or bladder

increased risk of life-threatening complications and

loss of fertility

Aboubakr Elnashar

Potential complications

751 cases reviewed 218 resulted in major surgery or interventional

radiology procedures (primary or emergency) The total planned primary (nonemergency) interventions performed were 66 (87) which included 3 hysterectomies 14 laparotomies and 49 uterine artery embolizations or ligations There were 98 (130) emergency interventions which included 36 hysterectomies 40 laparotomies and 22 uterine artery embolizations or ligations (Timor-Tritsch et al 2014)

(Immediate or delayed) Need secondary tt for blood loss ge200 mL or blood transfusion Complications are most often when the following

tt used alone

bull Single IM MTX

bull DampC

bull UAE Aboubakr Elnashar

lowest complication rate

1 Local and US directed MTX injection with or

without additional IM MTX

2 Surgical excision by hysteroscopic guidance

Aboubakr Elnashar

Management approaches I Surgical Excision Laparotomy or Hysterectomy or Laparoscopic or Hysteroscopic followed by DampC II Minimally invasive local injection of MTX or Kcl or UAE in combination with IM MTX Medical tt alone not recommended

Aboubakr Elnashar

Medical 1 Systemic single-dose MTX 1 mgkg or 50 mgm2 of body surface area complication rate 646 second tt when the fetal heart beat did not cease after several days

High failure rate slow action and questionable ability to stop cardiac activity and placental expansion The expected result can take days and all the while GS the embryo or fetus and its vascularity are growing Secondary tt has to address a larger gestation with more abundant vascularization

Aboubakr Elnashar

Systemic MTX as a single tt should be avoided 1 Waiting days for its effect to stop the heart beats which may not happen 2 It also led to the additional growth of the embryofetus as well as the vascularization of GS 3 Wastes precious time

Aboubakr Elnashar

2 Systemic multidose sequential MTX Two to three IM (1 mgkg BW or 50 mgmm2 of surface area) at an interval of 2 or 3 days over the course of a week

Cumulative adverse effects on the liver and bone marrow Success rate 75 Hysterectomy 6 Best results βHCG le 5000 mUmL Fibrous tissue within the scar around GS can delay systemic MTX absorption into GS Aboubakr Elnashar

with US guidance

Indications

hemodynamically stable

unruptured CSP

le8w gestation

myometrial thickness between GS and bladder

le 2 mm

Aboubakr Elnashar

Approach

TV approach is favored over TA

1 better visualization of the needle 2 shorter distance to reach the sac 3 decreased risk of bladder injury TAS guidance slighter higher complication rate (15) than those

using TVS guidance

Aboubakr Elnashar

Steps

1 After confirming the placement of needle 25 mg

of MTX in 1 mL of solution is injected slowly in

the GS

2 25 mg is injected outside GS as the needle is

withdrawn preferably the placental site

3 TVS 60-90 m after the procedure confirm

cessation of FH and to identify local bleeding

4 IM of 25 mg MTX (for a total combined dose of

75 mg) before discharge from our unit

5 24-48 h follow-up scan Close monitoring

hge may still occur

Aboubakr Elnashar

TVS -guided intragestational-sac injection of MTX in a

live CSP at 6 w 4 days The arrow points to the needle

in place (F = fetus) Aboubakr Elnashar

Advantages

No anesthesia

Complications fewest 108

most effective intervention

embryocide locally

avoidance of systemic side effects

more rapid interruption of the pregnancy

Aboubakr Elnashar

Aspiration of gestational sac fluid injection of methotrexate in the sac injection of homeostatic agent and pituitrin in the uterine muscle layer and injection of triple anti-inflammatory drugs around the uterus in 12 patients with CSP (Kong et al 2014)

Ultrasonography-guided multidrug interventional therapy for CSP is a new safe effective minimally invasive method

2 Use of a Foley balloon catheter

Indications

1 Alone (usually in gestations of 5ndash7 w) in the

hope of stopping the evolution of the pregnancy

by placing pressure on a small GS

2 In conjunction with another tt

3 Backup if bleeding occurs

Steps GA not required TAS guidance Or TVS guidance allow for more precise placement and assess the pressure avoiding over inflation of the balloon Catheter is kept 24 to 48 h with the outer end of the catheter fastened to the patientrsquos thigh Antibiotics Reevaluate after 48H Aboubakr Elnashar

3 UAE alone or in combination Indication 1 As a rescue procedure in the case of significant

bleeding or an A-VM 2 Concurrent with MTH Not as a primary tt delay between tt and effect allows the gestation to

High failure rate slow action and questionable ability to stop cardiac activity and placental expansion The expected result can take days and all the while GS the embryo or fetus and its vascularity are growing Secondary tt has to address a larger gestation with more abundant vascularization

Aboubakr Elnashar

Systemic MTX as a single tt should be avoided 1 Waiting days for its effect to stop the heart beats which may not happen 2 It also led to the additional growth of the embryofetus as well as the vascularization of GS 3 Wastes precious time

1 Surgical repair of the uterine dehiscence (niche) in patients with previous CS while not pregnant

Ben Nagi et al reported on a successful surgical repair Donnez et al hysteroscopic repair Klemm et al laparoscopic-assisted vaginal repair Yalcinkaya et al robotic-assisted laparoscopic repair More research is necessary before making recommendations for such surgical tt to prevent CSP

Aboubakr Elnashar

2 Specific surgical technique single- or double-layer closure of the incision can minimize or avoid a CSP

Aboubakr Elnashar

SUMMARY CSP

An uncommon but potentially life-threatening

The incidence is rising as CSR is rising

Precursor of morbidly adherent placenta

Do not confuse CSP with ectopic pregnancy

Early diagnosis is important TVS is the most

effective and preferred diagnostic tool

A key first step Determine whether heart activity is

present

Aboubakr Elnashar

If heart activity is documented Counsel the patient

inform the patient of the risks of pregnancy

continuation

If continuation an additional counseling session

risks

If termination a reliable tt that stops fetal heart beat

without delay

Avoid single tts unlikely to be effective

DampC

suction curettage

single-dose IM MTX and

UAE

Aboubakr Elnashar

Consider combination treatments best results

direct injection of MTX or Kcl into GS with TVS

guidance

Keep a catheter at hand

At the time of discharging after a CS in a future

pregnancy an early visit for TVS is important

Abstract

Heterotopic cesarean scar pregnancy is a rare life-threatening form of

ectopic pregnancy To provide information regarding the clinical

manifestations diagnosis management and prognosis of this condition

we reviewed all cases reported in the English literature All literature on

heterotopic cesarean scar pregnancy was retrieved by searching the

PubMed database and tracking references of the relevant literature Full

texts were reviewed and clinical manifestations diagnostic methods and

the relationship between the treatment and prognosis were summarized A

total of 14 patients with heterotopic cesarean scar pregnancies were

identified including 6 spontaneous pregnancies and 8 following in vitro

fertilization-embryo transfer Gestational ages at diagnosis ranged from 5

weeks to 8 weeks 4 days Only 5 cases presented with vaginal bleeding

and the others were asymptomatic All 14 cases were diagnosed by

transvaginal sonography One patient with no future fertility requirements

underwent pregnancy termination by methotrexate Of the remaining 13

patients who desired to preserve their intrauterine gestations 10 were

treated by sonographically guided selective embryo reduction in situ (by

SUMMARY CSP

An uncommon but potentially life-threatening

The incidence is rising as CSR is rising

Precursor of morbidly adherent placenta

Do not confuse CSP with ectopic pregnancy

Early diagnosis is important TVS is the most

effective and preferred diagnostic tool

A key first step Determine whether heart activity is

present

Aboubakr Elnashar

If heart activity is documented Counsel the patient

inform the patient of the risks of pregnancy

continuation

If continuation an additional counseling session

risks

If termination a reliable tt that stops fetal heart beat

without delay

Avoid single tts unlikely to be effective

DampC

suction curettage

single-dose IM MTX and

UAE

Aboubakr Elnashar

Consider combination treatments best results

direct injection of MTX or Kcl into GS with TVS

guidance

Keep a catheter at hand

At the time of discharging after a CS in a future

pregnancy an early visit for TVS is important

Abstract

Heterotopic cesarean scar pregnancy is a rare life-threatening form of

ectopic pregnancy To provide information regarding the clinical

manifestations diagnosis management and prognosis of this condition

we reviewed all cases reported in the English literature All literature on

heterotopic cesarean scar pregnancy was retrieved by searching the

PubMed database and tracking references of the relevant literature Full

texts were reviewed and clinical manifestations diagnostic methods and

the relationship between the treatment and prognosis were summarized A

total of 14 patients with heterotopic cesarean scar pregnancies were

identified including 6 spontaneous pregnancies and 8 following in vitro

fertilization-embryo transfer Gestational ages at diagnosis ranged from 5

weeks to 8 weeks 4 days Only 5 cases presented with vaginal bleeding

and the others were asymptomatic All 14 cases were diagnosed by

transvaginal sonography One patient with no future fertility requirements

underwent pregnancy termination by methotrexate Of the remaining 13

patients who desired to preserve their intrauterine gestations 10 were

treated by sonographically guided selective embryo reduction in situ (by

Abstract

OBJECTIVE

To assess the efficacy and safety of primary surgical evacuation therapy

for cesarean scarpregnancy (CSP) of the first trimester and to evaluate its

possible prognostic factors

DESIGN

Retrospective consecutive cohort study

SETTING

Tertiary care university hospital

SUBJECT(S)

A cohort of patients with CSP and clear ultrasound images who underwent

primary surgical evacuation from January 2000 to December 2012

INTERVENTION(S)

Patients fulfilling the ultrasound criteria of CSP were further classified into

superficial and deep groups according to their implantation locations and

extents The final decision on the method of treatment including

methotrexate chemotherapy surgical evacuation and others was made by

the patients after consultation with the physician Pretreatment patient

3Termination of the pregnancy in first

trimester is recommended

4Immediate and decisive action is

recommended

Aboubakr Elnashar

IV All are correct regarding CSP treatment

except

1 Complications are most often when single

IM Methotrexate or DampC

2 Complications are at lowest rate with

Local and US directed MTX injection with

or without additional IM MTX

3 Use of a Foley balloon catheter is not

recommended

4 laparoscopy or laparotomy with excision

of the pregnancy may be best treatment

Aboubakr Elnashar

V For follow up after treatment of CSP

all are correct except 1 5 w are required to obtain clearance of

βHCG

2 TVS is done monthly to evaluate the size

of retained products of conception

3 Avoiding pregnancy for 12 to 24 months

4 In a future pregnancy an early visit for

TVS is important

Potential complications

751 cases reviewed 218 resulted in major surgery or interventional

radiology procedures (primary or emergency) The total planned primary (nonemergency) interventions performed were 66 (87) which included 3 hysterectomies 14 laparotomies and 49 uterine artery embolizations or ligations There were 98 (130) emergency interventions which included 36 hysterectomies 40 laparotomies and 22 uterine artery embolizations or ligations (Timor-Tritsch et al 2014)

(Immediate or delayed) Need secondary tt for blood loss ge200 mL or blood transfusion Complications are most often when the following

tt used alone

lowest complication rate

1 Local and US directed MTX injection with or

without additional IM MTX

2 Surgical excision by hysteroscopic guidance

Aboubakr Elnashar

Management approaches I Surgical Excision Laparotomy or Hysterectomy or Laparoscopic or Hysteroscopic followed by DampC II Minimally invasive local injection of MTX or Kcl or UAE in combination with IM MTX Medical tt alone not recommended

Aboubakr Elnashar

Medical 1 Systemic single-dose MTX 1 mgkg or 50 mgm2 of body surface area complication rate 646 second tt when the fetal heart beat did not cease after several days

High failure rate slow action and questionable ability to stop cardiac activity and placental expansion The expected result can take days and all the while GS the embryo or fetus and its vascularity are growing Secondary tt has to address a larger gestation with more abundant vascularization

Aboubakr Elnashar

Systemic MTX as a single tt should be avoided 1 Waiting days for its effect to stop the heart beats which may not happen 2 It also led to the additional growth of the embryofetus as well as the vascularization of GS 3 Wastes precious time

Aboubakr Elnashar

2 Systemic multidose sequential MTX Two to three IM (1 mgkg BW or 50 mgmm2 of surface area) at an interval of 2 or 3 days over the course of a week

Cumulative adverse effects on the liver and bone marrow Success rate 75 Hysterectomy 6 Best results βHCG le 5000 mUmL Fibrous tissue within the scar around GS can delay systemic MTX absorption into GS Aboubakr Elnashar

Minimally invasive

with US guidance

Indications

hemodynamically stable

unruptured CSP

le8w gestation

myometrial thickness between GS and bladder

le 2 mm

Aboubakr Elnashar

Approach

TV approach is favored over TA

1 better visualization of the needle 2 shorter distance to reach the sac 3 decreased risk of bladder injury TAS guidance slighter higher complication rate (15) than those

using TVS guidance

Aboubakr Elnashar

Steps

1 After confirming the placement of needle 25 mg

of MTX in 1 mL of solution is injected slowly in

the GS

2 25 mg is injected outside GS as the needle is

withdrawn preferably the placental site

3 TVS 60-90 m after the procedure confirm

cessation of FH and to identify local bleeding

4 IM of 25 mg MTX (for a total combined dose of

75 mg) before discharge from our unit

5 24-48 h follow-up scan Close monitoring

hge may still occur

more rapid interruption of the pregnancy

Aboubakr Elnashar

Aspiration of gestational sac fluid injection of methotrexate in the sac injection of homeostatic agent and pituitrin in the uterine muscle layer and injection of triple anti-inflammatory drugs around the uterus in 12 patients with CSP (Kong et al 2014)

Ultrasonography-guided multidrug interventional therapy for CSP is a new safe effective minimally invasive method

2 Use of a Foley balloon catheter

Indications

1 Alone (usually in gestations of 5ndash7 w) in the

hope of stopping the evolution of the pregnancy

by placing pressure on a small GS

2 In conjunction with another tt

3 Backup if bleeding occurs

French-12 size 10-mL silicone balloon catheter or French-14 catheter with a 30-mL balloon

Steps GA not required TAS guidance Or TVS guidance allow for more precise placement and assess the pressure avoiding over inflation of the balloon Catheter is kept 24 to 48 h with the outer end of the catheter fastened to the patientrsquos thigh Antibiotics Reevaluate after 48H Aboubakr Elnashar

3 UAE alone or in combination Indication 1 As a rescue procedure in the case of significant

bleeding or an A-VM 2 Concurrent with MTH Not as a primary tt delay between tt and effect allows the gestation to

grow and vascularity to increase Disadvantages 1 GA 2 Complication rate 47 3 Not the best 1st -line tt

Aboubakr Elnashar

Surgical excision

laparoscopy or laparotomy may be best tt

No response to conservative medical tt

Patient late to present

Allows for revision of the CS scar with new uterine closure that may minimize risk of recurrence Risks postoperative adhesions impair future fertility increased size of surgical wounds longer hospital stay and recovery increased risk of future placenta previaaccreta

Aboubakr Elnashar

Aboubakr Elnashar

1 Excision by laparotomy alone or in combination with hysteroscopy

18 cases 5 complications and only when used in an emergency situation

Aboubakr Elnashar

2 Laparoscopic excision Complication rate 306 Laparoscopy combined with hysteroscopy Complication rate 20

Aboubakr Elnashar

3 Hysteroscopy alone or in combination complication rate 138 Hysteroscopy combined with TA US guidance 9 cases no complications reasonable operative solution Hysteroscopy combined with mifepristone complication rate17

Aboubakr Elnashar

4 Suction aspiration or DampC alone or in

combination

Isolated D amp C should be avoided

1 Trophoblastic tissue and villi are implanted

within the myometrium D ampC is unlikely to expel

the GS without rupturing the uterine wall or

damaging the bladder

2 massive bleeding emergency laparotomies

loss of the uterus

3 exposed vessels in the cervical scar tissue bleed no muscle grid to contract and contain the profuse bleeding

4 Complication rate 62 (29ndash86)

bleeding complications necessitating 3rd -line tt that almost always was surgical Aboubakr Elnashar

MTX followed by suction curettage Mean blood loss 707 mL (100ndash2000 mL) tt failure 3 out of 45 despite insertion of a Foley balloon catheter If DampC is still the preferred tt of choice blood products should be available balloon catheter should be inserted in the cervix

Preoperative determination of CSP implantation depth and extent is important in selecting candidates for surgical treatment Primary single-step surgical evacuation was successful in most patients with superficial implantation but patients should be informed of the possibility of salvage interventions before undergoing surgical evacuation (Kong et

al 2014)

Aboubakr Elnashar

FOLLOW-UP Placenta is implanted mostly within fibrous

tissue absorption of the GS is slow after med tt

1 9 w to obtain clearance of βHCG

2 3 months for clearance of GS on TVS

1 βHCG weekly until it is undetectable

2 TVS Monthly to evaluate the size of retained

products of conception

Aboubakr Elnashar

3 SIS in a nonpregnant patient uterine wall integrity size of the cesarean scar which may relate to the possibility of uterine scar complications in future pregnancies 4 Early TVS After CSP After CS to confirm an intrauterine location of the new gestation

Aboubakr Elnashar

5 Avoiding pregnancy No guidelines 12 to 24 months 6 Repair of scar before future pregnancies not known whether required or not Severely deficient uterine scars 10 of women who have had prior CS but CSP are much more rare

Aboubakr Elnashar

Outcomes Uneventful viable pregnancies have been reported after all modalities of conservative management Recurrence rate 5 IU pregnancy 95 spontaneous pregnancy 88 Normal pregnancy 65 Spontaneous abortion 35 higher than expected

Aboubakr Elnashar

4 PREVENTION OF CSP

1 Surgical repair of the uterine dehiscence (niche) in patients with previous CS while not pregnant

Ben Nagi et al reported on a successful surgical repair Donnez et al hysteroscopic repair Klemm et al laparoscopic-assisted vaginal repair Yalcinkaya et al robotic-assisted laparoscopic repair More research is necessary before making recommendations for such surgical tt to prevent CSP

Aboubakr Elnashar

2 Specific surgical technique single- or double-layer closure of the incision can minimize or avoid a CSP

Aboubakr Elnashar

SUMMARY CSP

An uncommon but potentially life-threatening

The incidence is rising as CSR is rising

Precursor of morbidly adherent placenta

Do not confuse CSP with ectopic pregnancy

Early diagnosis is important TVS is the most

effective and preferred diagnostic tool

A key first step Determine whether heart activity is

present

Aboubakr Elnashar

If heart activity is documented Counsel the patient

inform the patient of the risks of pregnancy

If termination a reliable tt that stops fetal heart beat

without delay

Avoid single tts unlikely to be effective

DampC

suction curettage

single-dose IM MTX and

UAE

Aboubakr Elnashar

Consider combination treatments best results

direct injection of MTX or Kcl into GS with TVS

guidance

Keep a catheter at hand

At the time of discharging after a CS in a future

pregnancy an early visit for TVS is important

Aboubakr Elnashar

2 Systemic multidose sequential MTX Two to three IM (1 mgkg BW or 50 mgmm2 of surface area) at an interval of 2 or 3 days over the course of a week

Cumulative adverse effects on the liver and bone marrow Success rate 75 Hysterectomy 6 Best results βHCG le 5000 mUmL Fibrous tissue within the scar around GS can delay systemic MTX absorption into GS Aboubakr Elnashar

Minimally invasive

with US guidance

Indications

hemodynamically stable

unruptured CSP

le8w gestation

myometrial thickness between GS and bladder

le 2 mm

Aboubakr Elnashar

Approach

TV approach is favored over TA

1 better visualization of the needle 2 shorter distance to reach the sac 3 decreased risk of bladder injury TAS guidance slighter higher complication rate (15) than those

using TVS guidance

Aboubakr Elnashar

Steps

1 After confirming the placement of needle 25 mg

of MTX in 1 mL of solution is injected slowly in

the GS

2 25 mg is injected outside GS as the needle is

withdrawn preferably the placental site

3 TVS 60-90 m after the procedure confirm

cessation of FH and to identify local bleeding

4 IM of 25 mg MTX (for a total combined dose of

75 mg) before discharge from our unit

5 24-48 h follow-up scan Close monitoring

Aspiration of gestational sac fluid injection of methotrexate in the sac injection of homeostatic agent and pituitrin in the uterine muscle layer and injection of triple anti-inflammatory drugs around the uterus in 12 patients with CSP (Kong et al 2014)

Ultrasonography-guided multidrug interventional therapy for CSP is a new safe effective minimally invasive method

2 Use of a Foley balloon catheter

Indications

1 Alone (usually in gestations of 5ndash7 w) in the

hope of stopping the evolution of the pregnancy

by placing pressure on a small GS

2 In conjunction with another tt

4 Suction aspiration or DampC alone or in

combination

Isolated D amp C should be avoided

1 Trophoblastic tissue and villi are implanted

within the myometrium D ampC is unlikely to expel

the GS without rupturing the uterine wall or

damaging the bladder

2 massive bleeding emergency laparotomies

loss of the uterus

3 exposed vessels in the cervical scar tissue bleed no muscle grid to contract and contain the profuse bleeding

4 Complication rate 62 (29ndash86)

bleeding complications necessitating 3rd -line tt that almost always was surgical Aboubakr Elnashar

MTX followed by suction curettage Mean blood loss 707 mL (100ndash2000 mL) tt failure 3 out of 45 despite insertion of a Foley balloon catheter If DampC is still the preferred tt of choice blood products should be available balloon catheter should be inserted in the cervix

Preoperative determination of CSP implantation depth and extent is important in selecting candidates for surgical treatment Primary single-step surgical evacuation was successful in most patients with superficial implantation but patients should be informed of the possibility of salvage interventions before undergoing surgical evacuation (Kong et

al 2014)

Aboubakr Elnashar

FOLLOW-UP Placenta is implanted mostly within fibrous

tissue absorption of the GS is slow after med tt

1 9 w to obtain clearance of βHCG

2 3 months for clearance of GS on TVS

1 βHCG weekly until it is undetectable

2 TVS Monthly to evaluate the size of retained

products of conception

Aboubakr Elnashar

3 SIS in a nonpregnant patient uterine wall integrity size of the cesarean scar which may relate to the possibility of uterine scar complications in future pregnancies 4 Early TVS After CSP After CS to confirm an intrauterine location of the new gestation

Aboubakr Elnashar

5 Avoiding pregnancy No guidelines 12 to 24 months 6 Repair of scar before future pregnancies not known whether required or not Severely deficient uterine scars 10 of women who have had prior CS but CSP are much more rare

Aboubakr Elnashar

Outcomes Uneventful viable pregnancies have been reported after all modalities of conservative management Recurrence rate 5 IU pregnancy 95 spontaneous pregnancy 88 Normal pregnancy 65 Spontaneous abortion 35 higher than expected

Aboubakr Elnashar

4 PREVENTION OF CSP

1 Surgical repair of the uterine dehiscence (niche) in patients with previous CS while not pregnant

Ben Nagi et al reported on a successful surgical repair Donnez et al hysteroscopic repair Klemm et al laparoscopic-assisted vaginal repair Yalcinkaya et al robotic-assisted laparoscopic repair More research is necessary before making recommendations for such surgical tt to prevent CSP

Aboubakr Elnashar

2 Specific surgical technique single- or double-layer closure of the incision can minimize or avoid a CSP

Aboubakr Elnashar

SUMMARY CSP

An uncommon but potentially life-threatening

The incidence is rising as CSR is rising

Precursor of morbidly adherent placenta

Do not confuse CSP with ectopic pregnancy

Early diagnosis is important TVS is the most

effective and preferred diagnostic tool

A key first step Determine whether heart activity is

present

Aboubakr Elnashar

If heart activity is documented Counsel the patient

inform the patient of the risks of pregnancy

continuation

If continuation an additional counseling session

risks

If termination a reliable tt that stops fetal heart beat

without delay

Avoid single tts unlikely to be effective

DampC

suction curettage

single-dose IM MTX and

UAE

Aboubakr Elnashar

Consider combination treatments best results

direct injection of MTX or Kcl into GS with TVS

guidance

Keep a catheter at hand

At the time of discharging after a CS in a future

pregnancy an early visit for TVS is important

Potential complications

751 cases reviewed 218 resulted in major surgery or interventional

radiology procedures (primary or emergency) The total planned primary (nonemergency) interventions performed were 66 (87) which included 3 hysterectomies 14 laparotomies and 49 uterine artery embolizations or ligations There were 98 (130) emergency interventions which included 36 hysterectomies 40 laparotomies and 22 uterine artery embolizations or ligations (Timor-Tritsch et al 2014)

Management approaches I Surgical Excision Laparotomy or Hysterectomy or Laparoscopic or Hysteroscopic followed by DampC II Minimally invasive local injection of MTX or Kcl or UAE in combination with IM MTX Medical tt alone not recommended

Aboubakr Elnashar

Medical 1 Systemic single-dose MTX 1 mgkg or 50 mgm2 of body surface area complication rate 646 second tt when the fetal heart beat did not cease after several days

High failure rate slow action and questionable ability to stop cardiac activity and placental expansion The expected result can take days and all the while GS the embryo or fetus and its vascularity are growing Secondary tt has to address a larger gestation with more abundant vascularization

Aboubakr Elnashar

Systemic MTX as a single tt should be avoided 1 Waiting days for its effect to stop the heart beats which may not happen 2 It also led to the additional growth of the embryofetus as well as the vascularization of GS 3 Wastes precious time

Aboubakr Elnashar

2 Systemic multidose sequential MTX Two to three IM (1 mgkg BW or 50 mgmm2 of surface area) at an interval of 2 or 3 days over the course of a week

of MTX in 1 mL of solution is injected slowly in

the GS

2 25 mg is injected outside GS as the needle is

withdrawn preferably the placental site

4 PREVENTION OF CSP

1 Surgical repair of the uterine dehiscence (niche) in patients with previous CS while not pregnant

Ben Nagi et al reported on a successful surgical repair Donnez et al hysteroscopic repair Klemm et al laparoscopic-assisted vaginal repair Yalcinkaya et al robotic-assisted laparoscopic repair More research is necessary before making recommendations for such surgical tt to prevent CSP

Aboubakr Elnashar

2 Specific surgical technique single- or double-layer closure of the incision can minimize or avoid a CSP

Aboubakr Elnashar

SUMMARY CSP

An uncommon but potentially life-threatening

The incidence is rising as CSR is rising

Precursor of morbidly adherent placenta

Do not confuse CSP with ectopic pregnancy

Early diagnosis is important TVS is the most

effective and preferred diagnostic tool

A key first step Determine whether heart activity is

present

Aboubakr Elnashar

If heart activity is documented Counsel the patient

inform the patient of the risks of pregnancy

continuation

If continuation an additional counseling session

risks

If termination a reliable tt that stops fetal heart beat

without delay

Avoid single tts unlikely to be effective

DampC

suction curettage

single-dose IM MTX and

UAE

Aboubakr Elnashar

Consider combination treatments best results

direct injection of MTX or Kcl into GS with TVS

guidance

Keep a catheter at hand

At the time of discharging after a CS in a future

pregnancy an early visit for TVS is important

Abstract

Heterotopic cesarean scar pregnancy is a rare life-threatening form of

ectopic pregnancy To provide information regarding the clinical

manifestations diagnosis management and prognosis of this condition

we reviewed all cases reported in the English literature All literature on

heterotopic cesarean scar pregnancy was retrieved by searching the

PubMed database and tracking references of the relevant literature Full

texts were reviewed and clinical manifestations diagnostic methods and

the relationship between the treatment and prognosis were summarized A

total of 14 patients with heterotopic cesarean scar pregnancies were

identified including 6 spontaneous pregnancies and 8 following in vitro

fertilization-embryo transfer Gestational ages at diagnosis ranged from 5

weeks to 8 weeks 4 days Only 5 cases presented with vaginal bleeding

and the others were asymptomatic All 14 cases were diagnosed by

transvaginal sonography One patient with no future fertility requirements

underwent pregnancy termination by methotrexate Of the remaining 13

patients who desired to preserve their intrauterine gestations 10 were

treated by sonographically guided selective embryo reduction in situ (by

Abstract

Heterotopic cesarean scar pregnancy is a rare life-threatening form of

ectopic pregnancy To provide information regarding the clinical

manifestations diagnosis management and prognosis of this condition

we reviewed all cases reported in the English literature All literature on

heterotopic cesarean scar pregnancy was retrieved by searching the

PubMed database and tracking references of the relevant literature Full

texts were reviewed and clinical manifestations diagnostic methods and

the relationship between the treatment and prognosis were summarized A

total of 14 patients with heterotopic cesarean scar pregnancies were

identified including 6 spontaneous pregnancies and 8 following in vitro

fertilization-embryo transfer Gestational ages at diagnosis ranged from 5

weeks to 8 weeks 4 days Only 5 cases presented with vaginal bleeding

and the others were asymptomatic All 14 cases were diagnosed by

transvaginal sonography One patient with no future fertility requirements

underwent pregnancy termination by methotrexate Of the remaining 13

patients who desired to preserve their intrauterine gestations 10 were

treated by sonographically guided selective embryo reduction in situ (by

Abstract

OBJECTIVE

To assess the efficacy and safety of primary surgical evacuation therapy

for cesarean scarpregnancy (CSP) of the first trimester and to evaluate its

possible prognostic factors

DESIGN

Retrospective consecutive cohort study

SETTING

Tertiary care university hospital

SUBJECT(S)

A cohort of patients with CSP and clear ultrasound images who underwent

primary surgical evacuation from January 2000 to December 2012

INTERVENTION(S)

Patients fulfilling the ultrasound criteria of CSP were further classified into

superficial and deep groups according to their implantation locations and

extents The final decision on the method of treatment including

methotrexate chemotherapy surgical evacuation and others was made by

the patients after consultation with the physician Pretreatment patient

I All are correct regarding CS scar

1 Incidence is rising

2Asymptomatic in 13 of cases

3Time of presentation is commonly 2nd trimester

4Diagnosis is missed in 14 of cases

Aboubakr Elnashar

II Sonographic criteria of CSP include

all except

1 Empty uterus with a clearly visualized

endometrium

2 Empty cervical canal

3 Gestational sac

within the anterior portion of lower uterine

segment

at site of the cesarean scar

4 Sliding organ sign is positive

Aboubakr Elnashar

III For treatment of CSP all are correct

except

1Anterior uterine wall thickness is important

2With pregnancy continuation hysterectomy

rate is 17

3Termination of the pregnancy in first

trimester is recommended

4Immediate and decisive action is

recommended

Aboubakr Elnashar

IV All are correct regarding CSP treatment

except

1 Complications are most often when single

IM Methotrexate or DampC

2 Complications are at lowest rate with

Local and US directed MTX injection with

or without additional IM MTX

3 Use of a Foley balloon catheter is not

recommended

4 laparoscopy or laparotomy with excision

of the pregnancy may be best treatment

Aboubakr Elnashar

V For follow up after treatment of CSP

all are correct except 1 5 w are required to obtain clearance of

βHCG

2 TVS is done monthly to evaluate the size

of retained products of conception

3 Avoiding pregnancy for 12 to 24 months

4 In a future pregnancy an early visit for

TVS is important

the GS without rupturing the uterine wall or

damaging the bladder

3 exposed vessels in the cervical scar tissue bleed no muscle grid to contract and contain the profuse bleeding

4 Complication rate 62 (29ndash86)

MTX followed by suction curettage Mean blood loss 707 mL (100ndash2000 mL) tt failure 3 out of 45 despite insertion of a Foley balloon catheter If DampC is still the preferred tt of choice blood products should be available balloon catheter should be inserted in the cervix

Preoperative determination of CSP implantation depth and extent is important in selecting candidates for surgical treatment Primary single-step surgical evacuation was successful in most patients with superficial implantation but patients should be informed of the possibility of salvage interventions before undergoing surgical evacuation (Kong et

al 2014)

Aboubakr Elnashar

FOLLOW-UP Placenta is implanted mostly within fibrous

tissue absorption of the GS is slow after med tt

1 9 w to obtain clearance of βHCG

2 3 months for clearance of GS on TVS

1 βHCG weekly until it is undetectable

2 TVS Monthly to evaluate the size of retained

products of conception

Aboubakr Elnashar

3 SIS in a nonpregnant patient uterine wall integrity size of the cesarean scar which may relate to the possibility of uterine scar complications in future pregnancies 4 Early TVS After CSP After CS to confirm an intrauterine location of the new gestation

Aboubakr Elnashar

5 Avoiding pregnancy No guidelines 12 to 24 months 6 Repair of scar before future pregnancies not known whether required or not Severely deficient uterine scars 10 of women who have had prior CS but CSP are much more rare

Aboubakr Elnashar

Outcomes Uneventful viable pregnancies have been reported after all modalities of conservative management Recurrence rate 5 IU pregnancy 95 spontaneous pregnancy 88 Normal pregnancy 65 Spontaneous abortion 35 higher than expected

Aboubakr Elnashar

4 PREVENTION OF CSP

1 Surgical repair of the uterine dehiscence (niche) in patients with previous CS while not pregnant

Ben Nagi et al reported on a successful surgical repair Donnez et al hysteroscopic repair Klemm et al laparoscopic-assisted vaginal repair Yalcinkaya et al robotic-assisted laparoscopic repair More research is necessary before making recommendations for such surgical tt to prevent CSP

Aboubakr Elnashar

2 Specific surgical technique single- or double-layer closure of the incision can minimize or avoid a CSP

Aboubakr Elnashar

SUMMARY CSP

An uncommon but potentially life-threatening

The incidence is rising as CSR is rising

Precursor of morbidly adherent placenta

Do not confuse CSP with ectopic pregnancy

Early diagnosis is important TVS is the most

effective and preferred diagnostic tool

A key first step Determine whether heart activity is

present

Potential complications

751 cases reviewed 218 resulted in major surgery or interventional

radiology procedures (primary or emergency) The total planned primary (nonemergency) interventions performed were 66 (87) which included 3 hysterectomies 14 laparotomies and 49 uterine artery embolizations or ligations There were 98 (130) emergency interventions which included 36 hysterectomies 40 laparotomies and 22 uterine artery embolizations or ligations (Timor-Tritsch et al 2014)

(Immediate or delayed) Need secondary tt for blood loss ge200 mL or blood transfusion Complications are most often when the following

2 Surgical excision by hysteroscopic guidance

Aboubakr Elnashar

Management approaches I Surgical Excision Laparotomy or Hysterectomy or Laparoscopic or Hysteroscopic followed by DampC II Minimally invasive local injection of MTX or Kcl or UAE in combination with IM MTX Medical tt alone not recommended

Aboubakr Elnashar

Medical 1 Systemic single-dose MTX 1 mgkg or 50 mgm2 of body surface area complication rate 646 second tt when the fetal heart beat did not cease after several days

High failure rate slow action and questionable ability to stop cardiac activity and placental expansion The expected result can take days and all the while GS the embryo or fetus and its vascularity are growing Secondary tt has to address a larger gestation with more abundant vascularization

Aboubakr Elnashar

Systemic MTX as a single tt should be avoided 1 Waiting days for its effect to stop the heart beats which may not happen 2 It also led to the additional growth of the embryofetus as well as the vascularization of GS 3 Wastes precious time

Aboubakr Elnashar

2 Systemic multidose sequential MTX Two to three IM (1 mgkg BW or 50 mgmm2 of surface area) at an interval of 2 or 3 days over the course of a week

Cumulative adverse effects on the liver and bone marrow Success rate 75 Hysterectomy 6 Best results βHCG le 5000 mUmL Fibrous tissue within the scar around GS can delay systemic MTX absorption into GS Aboubakr Elnashar

Approach

TV approach is favored over TA

1 better visualization of the needle 2 shorter distance to reach the sac 3 decreased risk of bladder injury TAS guidance slighter higher complication rate (15) than those

using TVS guidance

Aboubakr Elnashar

Steps

1 After confirming the placement of needle 25 mg

of MTX in 1 mL of solution is injected slowly in

the GS

2 25 mg is injected outside GS as the needle is

withdrawn preferably the placental site

3 TVS 60-90 m after the procedure confirm

cessation of FH and to identify local bleeding

Aspiration of gestational sac fluid injection of methotrexate in the sac injection of homeostatic agent and pituitrin in the uterine muscle layer and injection of triple anti-inflammatory drugs around the uterus in 12 patients with CSP (Kong et al 2014)

Ultrasonography-guided multidrug interventional therapy for CSP is a new safe effective minimally invasive method

2 Use of a Foley balloon catheter

Indications

1 Alone (usually in gestations of 5ndash7 w) in the

hope of stopping the evolution of the pregnancy

by placing pressure on a small GS

2 In conjunction with another tt

A cohort of patients with CSP and clear ultrasound images who underwent

primary surgical evacuation from January 2000 to December 2012

INTERVENTION(S)

Patients fulfilling the ultrasound criteria of CSP were further classified into

superficial and deep groups according to their implantation locations and

extents The final decision on the method of treatment including

methotrexate chemotherapy surgical evacuation and others was made by

the patients after consultation with the physician Pretreatment patient

increased risk of life-threatening complications and

loss of fertility

Aboubakr Elnashar

Potential complications

751 cases reviewed 218 resulted in major surgery or interventional

radiology procedures (primary or emergency) The total planned primary (nonemergency) interventions performed were 66 (87) which included 3 hysterectomies 14 laparotomies and 49 uterine artery embolizations or ligations There were 98 (130) emergency interventions which included 36 hysterectomies 40 laparotomies and 22 uterine artery embolizations or ligations (Timor-Tritsch et al 2014)

(Immediate or delayed) Need secondary tt for blood loss ge200 mL or blood transfusion Complications are most often when the following

2 Surgical excision by hysteroscopic guidance

Aboubakr Elnashar

Management approaches I Surgical Excision Laparotomy or Hysterectomy or Laparoscopic or Hysteroscopic followed by DampC II Minimally invasive local injection of MTX or Kcl or UAE in combination with IM MTX Medical tt alone not recommended

Aboubakr Elnashar

Medical 1 Systemic single-dose MTX 1 mgkg or 50 mgm2 of body surface area complication rate 646 second tt when the fetal heart beat did not cease after several days

High failure rate slow action and questionable ability to stop cardiac activity and placental expansion The expected result can take days and all the while GS the embryo or fetus and its vascularity are growing Secondary tt has to address a larger gestation with more abundant vascularization

Aboubakr Elnashar

Systemic MTX as a single tt should be avoided 1 Waiting days for its effect to stop the heart beats which may not happen 2 It also led to the additional growth of the embryofetus as well as the vascularization of GS 3 Wastes precious time

Aboubakr Elnashar

2 Systemic multidose sequential MTX Two to three IM (1 mgkg BW or 50 mgmm2 of surface area) at an interval of 2 or 3 days over the course of a week

Cumulative adverse effects on the liver and bone marrow Success rate 75 Hysterectomy 6 Best results βHCG le 5000 mUmL Fibrous tissue within the scar around GS can delay systemic MTX absorption into GS Aboubakr Elnashar

Approach

TV approach is favored over TA

Steps

1 After confirming the placement of needle 25 mg

of MTX in 1 mL of solution is injected slowly in

the GS

2 25 mg is injected outside GS as the needle is

withdrawn preferably the placental site

3 TVS 60-90 m after the procedure confirm

cessation of FH and to identify local bleeding

4 IM of 25 mg MTX (for a total combined dose of

75 mg) before discharge from our unit

SUMMARY CSP

An uncommon but potentially life-threatening

The incidence is rising as CSR is rising

Precursor of morbidly adherent placenta

Do not confuse CSP with ectopic pregnancy

Early diagnosis is important TVS is the most

effective and preferred diagnostic tool

2 Specific surgical technique single- or double-layer closure of the incision can minimize or avoid a CSP

Aboubakr Elnashar

SUMMARY CSP

An uncommon but potentially life-threatening

The incidence is rising as CSR is rising

Precursor of morbidly adherent placenta

Do not confuse CSP with ectopic pregnancy

Early diagnosis is important TVS is the most

effective and preferred diagnostic tool

A key first step Determine whether heart activity is

present

If heart activity is documented Counsel the patient

inform the patient of the risks of pregnancy

Aboubakr Elnashar

Consider combination treatments best results

direct injection of MTX or Kcl into GS with TVS

SUMMARY CSP

An uncommon but potentially life-threatening

The incidence is rising as CSR is rising

Precursor of morbidly adherent placenta

Do not confuse CSP with ectopic pregnancy

Early diagnosis is important TVS is the most

effective and preferred diagnostic tool

A key first step Determine whether heart activity is

present

Abstract

OBJECTIVE

To assess the efficacy and safety of primary surgical evacuation therapy

for cesarean scarpregnancy (CSP) of the first trimester and to evaluate its

possible prognostic factors

DESIGN

Retrospective consecutive cohort study

SETTING

Tertiary care university hospital

SUBJECT(S)

A cohort of patients with CSP and clear ultrasound images who underwent

primary surgical evacuation from January 2000 to December 2012

INTERVENTION(S)

Patients fulfilling the ultrasound criteria of CSP were further classified into

superficial and deep groups according to their implantation locations and

extents The final decision on the method of treatment including

methotrexate chemotherapy surgical evacuation and others was made by

the patients after consultation with the physician Pretreatment patient

I All are correct regarding CS scar

1 Incidence is rising

2Asymptomatic in 13 of cases

3Time of presentation is commonly 2nd trimester

4Diagnosis is missed in 14 of cases

Aboubakr Elnashar

II Sonographic criteria of CSP include

all except

1 Empty uterus with a clearly visualized

endometrium

2 Empty cervical canal

3 Gestational sac

within the anterior portion of lower uterine

segment

at site of the cesarean scar

4 Sliding organ sign is positive

Aboubakr Elnashar

III For treatment of CSP all are correct

except

1Anterior uterine wall thickness is important

2With pregnancy continuation hysterectomy

rate is 17

3Termination of the pregnancy in first

trimester is recommended

4Immediate and decisive action is

recommended

Aboubakr Elnashar

IV All are correct regarding CSP treatment

except

1 Complications are most often when single

IM Methotrexate or DampC

2 Complications are at lowest rate with

Local and US directed MTX injection with

or without additional IM MTX

3 Use of a Foley balloon catheter is not

recommended

4 laparoscopy or laparotomy with excision

of the pregnancy may be best treatment

Aboubakr Elnashar

V For follow up after treatment of CSP

all are correct except 1 5 w are required to obtain clearance of

βHCG

2 TVS is done monthly to evaluate the size

of retained products of conception

3 Avoiding pregnancy for 12 to 24 months

4 In a future pregnancy an early visit for

TVS is important

with US guidance

Indications

hemodynamically stable

unruptured CSP

le8w gestation

myometrial thickness between GS and bladder

le 2 mm

Aboubakr Elnashar

Approach

TV approach is favored over TA

1 better visualization of the needle 2 shorter distance to reach the sac 3 decreased risk of bladder injury TAS guidance slighter higher complication rate (15) than those

using TVS guidance

Aboubakr Elnashar

Steps

1 After confirming the placement of needle 25 mg

of MTX in 1 mL of solution is injected slowly in

the GS

2 25 mg is injected outside GS as the needle is

withdrawn preferably the placental site

3 TVS 60-90 m after the procedure confirm

cessation of FH and to identify local bleeding

4 IM of 25 mg MTX (for a total combined dose of

75 mg) before discharge from our unit

5 24-48 h follow-up scan Close monitoring

hge may still occur

Aboubakr Elnashar

SUMMARY CSP

An uncommon but potentially life-threatening

The incidence is rising as CSR is rising

Precursor of morbidly adherent placenta

Do not confuse CSP with ectopic pregnancy

Early diagnosis is important TVS is the most

effective and preferred diagnostic tool

A key first step Determine whether heart activity is

present

Aboubakr Elnashar

If heart activity is documented Counsel the patient

inform the patient of the risks of pregnancy

continuation

If continuation an additional counseling session

risks

If termination a reliable tt that stops fetal heart beat

without delay

Avoid single tts unlikely to be effective

DampC

suction curettage

single-dose IM MTX and

UAE

Aboubakr Elnashar

Consider combination treatments best results

direct injection of MTX or Kcl into GS with TVS

guidance

Keep a catheter at hand

At the time of discharging after a CS in a future

pregnancy an early visit for TVS is important

Abstract

Heterotopic cesarean scar pregnancy is a rare life-threatening form of

ectopic pregnancy To provide information regarding the clinical

manifestations diagnosis management and prognosis of this condition

we reviewed all cases reported in the English literature All literature on

heterotopic cesarean scar pregnancy was retrieved by searching the

PubMed database and tracking references of the relevant literature Full

texts were reviewed and clinical manifestations diagnostic methods and

the relationship between the treatment and prognosis were summarized A

total of 14 patients with heterotopic cesarean scar pregnancies were

identified including 6 spontaneous pregnancies and 8 following in vitro

fertilization-embryo transfer Gestational ages at diagnosis ranged from 5

weeks to 8 weeks 4 days Only 5 cases presented with vaginal bleeding

and the others were asymptomatic All 14 cases were diagnosed by

transvaginal sonography One patient with no future fertility requirements

underwent pregnancy termination by methotrexate Of the remaining 13

patients who desired to preserve their intrauterine gestations 10 were

treated by sonographically guided selective embryo reduction in situ (by

Author information

Abstract

OBJECTIVE

To assess the efficacy and safety of primary surgical evacuation therapy

for cesarean scarpregnancy (CSP) of the first trimester and to evaluate its

possible prognostic factors

DESIGN

Retrospective consecutive cohort study

SETTING

Tertiary care university hospital

SUBJECT(S)

A cohort of patients with CSP and clear ultrasound images who underwent

primary surgical evacuation from January 2000 to December 2012

INTERVENTION(S)

Patients fulfilling the ultrasound criteria of CSP were further classified into

superficial and deep groups according to their implantation locations and

extents The final decision on the method of treatment including

methotrexate chemotherapy surgical evacuation and others was made by

the patients after consultation with the physician Pretreatment patient

I All are correct regarding CS scar

pregnancy (CSP) except

1 Incidence is rising

2Asymptomatic in 13 of cases

3Time of presentation is commonly 2nd trimester

4Diagnosis is missed in 14 of cases

Aboubakr Elnashar

II Sonographic criteria of CSP include

all except

1 Empty uterus with a clearly visualized

endometrium

2 Empty cervical canal

3 Gestational sac

within the anterior portion of lower uterine

segment

at site of the cesarean scar

4 Sliding organ sign is positive

Aboubakr Elnashar

III For treatment of CSP all are correct

except

1Anterior uterine wall thickness is important

2With pregnancy continuation hysterectomy

rate is 17

3Termination of the pregnancy in first

trimester is recommended

4Immediate and decisive action is

recommended

Aboubakr Elnashar

IV All are correct regarding CSP treatment

except

1 Complications are most often when single

IM Methotrexate or DampC

2 Complications are at lowest rate with

Local and US directed MTX injection with

or without additional IM MTX

3 Use of a Foley balloon catheter is not

recommended

4 laparoscopy or laparotomy with excision

of the pregnancy may be best treatment

Aboubakr Elnashar

V For follow up after treatment of CSP

all are correct except 1 5 w are required to obtain clearance of

βHCG

2 TVS is done monthly to evaluate the size

of retained products of conception

3 Avoiding pregnancy for 12 to 24 months

4 In a future pregnancy an early visit for

TVS is important

Aboubakr Elnashar

Page 44: Cesarean Scar Pregnancy

Approach

TV approach is favored over TA

1 better visualization of the needle 2 shorter distance to reach the sac 3 decreased risk of bladder injury TAS guidance slighter higher complication rate (15) than those

using TVS guidance

Aboubakr Elnashar

Steps

1 After confirming the placement of needle 25 mg

of MTX in 1 mL of solution is injected slowly in

the GS

2 25 mg is injected outside GS as the needle is

withdrawn preferably the placental site

3 TVS 60-90 m after the procedure confirm

cessation of FH and to identify local bleeding

4 IM of 25 mg MTX (for a total combined dose of

75 mg) before discharge from our unit

5 24-48 h follow-up scan Close monitoring

hge may still occur

Aboubakr Elnashar

TVS -guided intragestational-sac injection of MTX in a

live CSP at 6 w 4 days The arrow points to the needle

in place (F = fetus) Aboubakr Elnashar

Advantages

No anesthesia

Complications fewest 108

most effective intervention

decrease the need for additional interventions

provides a higher concentration of the

embryocide locally

avoidance of systemic side effects

more rapid interruption of the pregnancy

Aboubakr Elnashar

Aspiration of gestational sac fluid injection of methotrexate in the sac injection of homeostatic agent and pituitrin in the uterine muscle layer and injection of triple anti-inflammatory drugs around the uterus in 12 patients with CSP (Kong et al 2014)

Ultrasonography-guided multidrug interventional therapy for CSP is a new safe effective minimally invasive method

2 Use of a Foley balloon catheter

Indications

1 Alone (usually in gestations of 5ndash7 w) in the

hope of stopping the evolution of the pregnancy

by placing pressure on a small GS

2 In conjunction with another tt

3 Backup if bleeding occurs

French-12 size 10-mL silicone balloon catheter or French-14 catheter with a 30-mL balloon

Aboubakr Elnashar

The catheter with the

balloon inflated with 5

mL of saline

TV power Doppler image

of the inflated balloon

(B) in a case of a CSP at

6 w 4 days after

injection of MXT

Aboubakr Elnashar

Steps GA not required TAS guidance Or TVS guidance allow for more precise placement and assess the pressure avoiding over inflation of the balloon Catheter is kept 24 to 48 h with the outer end of the catheter fastened to the patientrsquos thigh Antibiotics Reevaluate after 48H Aboubakr Elnashar

3 UAE alone or in combination Indication 1 As a rescue procedure in the case of significant

bleeding or an A-VM 2 Concurrent with MTH Not as a primary tt delay between tt and effect allows the gestation to

grow and vascularity to increase Disadvantages 1 GA 2 Complication rate 47 3 Not the best 1st -line tt

Aboubakr Elnashar

Surgical excision

laparoscopy or laparotomy may be best tt

No response to conservative medical tt

Patient late to present

Allows for revision of the CS scar with new uterine closure that may minimize risk of recurrence Risks postoperative adhesions impair future fertility increased size of surgical wounds longer hospital stay and recovery increased risk of future placenta previaaccreta

Aboubakr Elnashar

Aboubakr Elnashar

1 Excision by laparotomy alone or in combination with hysteroscopy

18 cases 5 complications and only when used in an emergency situation

Aboubakr Elnashar

2 Laparoscopic excision Complication rate 306 Laparoscopy combined with hysteroscopy Complication rate 20

Aboubakr Elnashar

3 Hysteroscopy alone or in combination complication rate 138 Hysteroscopy combined with TA US guidance 9 cases no complications reasonable operative solution Hysteroscopy combined with mifepristone complication rate17

Aboubakr Elnashar

4 Suction aspiration or DampC alone or in

combination

Isolated D amp C should be avoided

1 Trophoblastic tissue and villi are implanted

within the myometrium D ampC is unlikely to expel

the GS without rupturing the uterine wall or

damaging the bladder

2 massive bleeding emergency laparotomies

loss of the uterus

3 exposed vessels in the cervical scar tissue bleed no muscle grid to contract and contain the profuse bleeding

4 Complication rate 62 (29ndash86)

bleeding complications necessitating 3rd -line tt that almost always was surgical Aboubakr Elnashar

MTX followed by suction curettage Mean blood loss 707 mL (100ndash2000 mL) tt failure 3 out of 45 despite insertion of a Foley balloon catheter If DampC is still the preferred tt of choice blood products should be available balloon catheter should be inserted in the cervix

Preoperative determination of CSP implantation depth and extent is important in selecting candidates for surgical treatment Primary single-step surgical evacuation was successful in most patients with superficial implantation but patients should be informed of the possibility of salvage interventions before undergoing surgical evacuation (Kong et

al 2014)

Aboubakr Elnashar

FOLLOW-UP Placenta is implanted mostly within fibrous

tissue absorption of the GS is slow after med tt

1 9 w to obtain clearance of βHCG

2 3 months for clearance of GS on TVS

1 βHCG weekly until it is undetectable

2 TVS Monthly to evaluate the size of retained

products of conception

Aboubakr Elnashar

3 SIS in a nonpregnant patient uterine wall integrity size of the cesarean scar which may relate to the possibility of uterine scar complications in future pregnancies 4 Early TVS After CSP After CS to confirm an intrauterine location of the new gestation

Aboubakr Elnashar

5 Avoiding pregnancy No guidelines 12 to 24 months 6 Repair of scar before future pregnancies not known whether required or not Severely deficient uterine scars 10 of women who have had prior CS but CSP are much more rare

Aboubakr Elnashar

Outcomes Uneventful viable pregnancies have been reported after all modalities of conservative management Recurrence rate 5 IU pregnancy 95 spontaneous pregnancy 88 Normal pregnancy 65 Spontaneous abortion 35 higher than expected

Aboubakr Elnashar

4 PREVENTION OF CSP

1 Surgical repair of the uterine dehiscence (niche) in patients with previous CS while not pregnant

Ben Nagi et al reported on a successful surgical repair Donnez et al hysteroscopic repair Klemm et al laparoscopic-assisted vaginal repair Yalcinkaya et al robotic-assisted laparoscopic repair More research is necessary before making recommendations for such surgical tt to prevent CSP

Abstract

Heterotopic cesarean scar pregnancy is a rare life-threatening form of

ectopic pregnancy To provide information regarding the clinical

manifestations diagnosis management and prognosis of this condition

we reviewed all cases reported in the English literature All literature on

heterotopic cesarean scar pregnancy was retrieved by searching the

PubMed database and tracking references of the relevant literature Full

texts were reviewed and clinical manifestations diagnostic methods and

the relationship between the treatment and prognosis were summarized A

total of 14 patients with heterotopic cesarean scar pregnancies were

identified including 6 spontaneous pregnancies and 8 following in vitro

fertilization-embryo transfer Gestational ages at diagnosis ranged from 5

weeks to 8 weeks 4 days Only 5 cases presented with vaginal bleeding

and the others were asymptomatic All 14 cases were diagnosed by

transvaginal sonography One patient with no future fertility requirements

underwent pregnancy termination by methotrexate Of the remaining 13

patients who desired to preserve their intrauterine gestations 10 were

treated by sonographically guided selective embryo reduction in situ (by

Abstract

Heterotopic cesarean scar pregnancy is a rare life-threatening form of

ectopic pregnancy To provide information regarding the clinical

manifestations diagnosis management and prognosis of this condition

we reviewed all cases reported in the English literature All literature on

heterotopic cesarean scar pregnancy was retrieved by searching the

PubMed database and tracking references of the relevant literature Full

texts were reviewed and clinical manifestations diagnostic methods and

the relationship between the treatment and prognosis were summarized A

total of 14 patients with heterotopic cesarean scar pregnancies were

identified including 6 spontaneous pregnancies and 8 following in vitro

fertilization-embryo transfer Gestational ages at diagnosis ranged from 5

weeks to 8 weeks 4 days Only 5 cases presented with vaginal bleeding

and the others were asymptomatic All 14 cases were diagnosed by

transvaginal sonography One patient with no future fertility requirements

underwent pregnancy termination by methotrexate Of the remaining 13

patients who desired to preserve their intrauterine gestations 10 were

treated by sonographically guided selective embryo reduction in situ (by

Abstract

OBJECTIVE

To assess the efficacy and safety of primary surgical evacuation therapy

for cesarean scarpregnancy (CSP) of the first trimester and to evaluate its

possible prognostic factors

DESIGN

Retrospective consecutive cohort study

SETTING

Tertiary care university hospital

SUBJECT(S)

A cohort of patients with CSP and clear ultrasound images who underwent

primary surgical evacuation from January 2000 to December 2012

INTERVENTION(S)

Patients fulfilling the ultrasound criteria of CSP were further classified into

superficial and deep groups according to their implantation locations and

extents The final decision on the method of treatment including

methotrexate chemotherapy surgical evacuation and others was made by

the patients after consultation with the physician Pretreatment patient

I All are correct regarding CS scar

pregnancy (CSP) except

1 Incidence is rising

2Asymptomatic in 13 of cases

3Time of presentation is commonly 2nd trimester

4Diagnosis is missed in 14 of cases

Aboubakr Elnashar

II Sonographic criteria of CSP include

all except

1 Empty uterus with a clearly visualized

endometrium

2 Empty cervical canal

3 Gestational sac

within the anterior portion of lower uterine

segment

at site of the cesarean scar

4 Sliding organ sign is positive

Aboubakr Elnashar

III For treatment of CSP all are correct

except

1Anterior uterine wall thickness is important

2With pregnancy continuation hysterectomy

rate is 17

3Termination of the pregnancy in first

trimester is recommended

4Immediate and decisive action is

recommended

Aboubakr Elnashar

IV All are correct regarding CSP treatment

except

1 Complications are most often when single

IM Methotrexate or DampC

2 Complications are at lowest rate with

Local and US directed MTX injection with

or without additional IM MTX

3 Use of a Foley balloon catheter is not

recommended

4 laparoscopy or laparotomy with excision

of the pregnancy may be best treatment

Aboubakr Elnashar

V For follow up after treatment of CSP

all are correct except 1 5 w are required to obtain clearance of

βHCG

2 TVS is done monthly to evaluate the size

of retained products of conception

3 Avoiding pregnancy for 12 to 24 months

4 In a future pregnancy an early visit for

TVS is important

Aboubakr Elnashar

Page 49: Cesarean Scar Pregnancy

2 Use of a Foley balloon catheter

Indications

1 Alone (usually in gestations of 5ndash7 w) in the

hope of stopping the evolution of the pregnancy

by placing pressure on a small GS

2 In conjunction with another tt

3 Backup if bleeding occurs

French-12 size 10-mL silicone balloon catheter or French-14 catheter with a 30-mL balloon

balloon inflated with 5

of the inflated balloon

(B) in a case of a CSP at

6 w 4 days after

injection of MXT

Aboubakr Elnashar

Steps GA not required TAS guidance Or TVS guidance allow for more precise placement and assess the pressure avoiding over inflation of the balloon Catheter is kept 24 to 48 h with the outer end of the catheter fastened to the patientrsquos thigh Antibiotics Reevaluate after 48H Aboubakr Elnashar

3 UAE alone or in combination Indication 1 As a rescue procedure in the case of significant

bleeding or an A-VM 2 Concurrent with MTH Not as a primary tt delay between tt and effect allows the gestation to

grow and vascularity to increase Disadvantages 1 GA 2 Complication rate 47 3 Not the best 1st -line tt

Aboubakr Elnashar

Surgical excision

laparoscopy or laparotomy may be best tt

No response to conservative medical tt

Patient late to present

Allows for revision of the CS scar with new uterine closure that may minimize risk of recurrence Risks postoperative adhesions impair future fertility increased size of surgical wounds longer hospital stay and recovery increased risk of future placenta previaaccreta

Aboubakr Elnashar

Aboubakr Elnashar

1 Excision by laparotomy alone or in combination with hysteroscopy

18 cases 5 complications and only when used in an emergency situation

2 Laparoscopic excision Complication rate 306 Laparoscopy combined with hysteroscopy Complication rate 20

Aboubakr Elnashar

3 Hysteroscopy alone or in combination complication rate 138 Hysteroscopy combined with TA US guidance 9 cases no complications reasonable operative solution Hysteroscopy combined with mifepristone complication rate17

Aboubakr Elnashar

4 Suction aspiration or DampC alone or in

combination

Isolated D amp C should be avoided

1 Trophoblastic tissue and villi are implanted

within the myometrium D ampC is unlikely to expel

the GS without rupturing the uterine wall or

damaging the bladder

2 massive bleeding emergency laparotomies

loss of the uterus

3 exposed vessels in the cervical scar tissue bleed no muscle grid to contract and contain the profuse bleeding

4 Complication rate 62 (29ndash86)

bleeding complications necessitating 3rd -line tt that almost always was surgical Aboubakr Elnashar

MTX followed by suction curettage Mean blood loss 707 mL (100ndash2000 mL) tt failure 3 out of 45 despite insertion of a Foley balloon catheter If DampC is still the preferred tt of choice blood products should be available balloon catheter should be inserted in the cervix

Preoperative determination of CSP implantation depth and extent is important in selecting candidates for surgical treatment Primary single-step surgical evacuation was successful in most patients with superficial implantation but patients should be informed of the possibility of salvage interventions before undergoing surgical evacuation (Kong et

al 2014)

Aboubakr Elnashar

FOLLOW-UP Placenta is implanted mostly within fibrous

tissue absorption of the GS is slow after med tt

1 9 w to obtain clearance of βHCG

2 3 months for clearance of GS on TVS

1 βHCG weekly until it is undetectable

2 TVS Monthly to evaluate the size of retained

products of conception

Aboubakr Elnashar

3 SIS in a nonpregnant patient uterine wall integrity size of the cesarean scar which may relate to the possibility of uterine scar complications in future pregnancies 4 Early TVS After CSP After CS to confirm an intrauterine location of the new gestation

Aboubakr Elnashar

5 Avoiding pregnancy No guidelines 12 to 24 months 6 Repair of scar before future pregnancies not known whether required or not Severely deficient uterine scars 10 of women who have had prior CS but CSP are much more rare

Aboubakr Elnashar

Outcomes Uneventful viable pregnancies have been reported after all modalities of conservative management Recurrence rate 5 IU pregnancy 95 spontaneous pregnancy 88 Normal pregnancy 65 Spontaneous abortion 35 higher than expected

Aboubakr Elnashar

4 PREVENTION OF CSP

1 Surgical repair of the uterine dehiscence (niche) in patients with previous CS while not pregnant

Ben Nagi et al reported on a successful surgical repair Donnez et al hysteroscopic repair Klemm et al laparoscopic-assisted vaginal repair Yalcinkaya et al robotic-assisted laparoscopic repair More research is necessary before making recommendations for such surgical tt to prevent CSP

Aboubakr Elnashar

2 Specific surgical technique single- or double-layer closure of the incision can minimize or avoid a CSP

Aboubakr Elnashar

SUMMARY CSP

An uncommon but potentially life-threatening

The incidence is rising as CSR is rising

Precursor of morbidly adherent placenta

Do not confuse CSP with ectopic pregnancy

Early diagnosis is important TVS is the most

effective and preferred diagnostic tool

SUMMARY CSP

An uncommon but potentially life-threatening

The incidence is rising as CSR is rising

Precursor of morbidly adherent placenta

Do not confuse CSP with ectopic pregnancy

Early diagnosis is important TVS is the most

effective and preferred diagnostic tool

A key first step Determine whether heart activity is

present

Aboubakr Elnashar

If heart activity is documented Counsel the patient

inform the patient of the risks of pregnancy

continuation

If continuation an additional counseling session

If termination a reliable tt that stops fetal heart beat

without delay

Avoid single tts unlikely to be effective

DampC

suction curettage

single-dose IM MTX and

UAE

Aboubakr Elnashar

Consider combination treatments best results

direct injection of MTX or Kcl into GS with TVS

guidance

Keep a catheter at hand

At the time of discharging after a CS in a future

pregnancy an early visit for TVS is important

Abstract

Heterotopic cesarean scar pregnancy is a rare life-threatening form of

ectopic pregnancy To provide information regarding the clinical

manifestations diagnosis management and prognosis of this condition

we reviewed all cases reported in the English literature All literature on

heterotopic cesarean scar pregnancy was retrieved by searching the

PubMed database and tracking references of the relevant literature Full

texts were reviewed and clinical manifestations diagnostic methods and

the relationship between the treatment and prognosis were summarized A

total of 14 patients with heterotopic cesarean scar pregnancies were

identified including 6 spontaneous pregnancies and 8 following in vitro

fertilization-embryo transfer Gestational ages at diagnosis ranged from 5

weeks to 8 weeks 4 days Only 5 cases presented with vaginal bleeding

and the others were asymptomatic All 14 cases were diagnosed by

transvaginal sonography One patient with no future fertility requirements

underwent pregnancy termination by methotrexate Of the remaining 13

patients who desired to preserve their intrauterine gestations 10 were

treated by sonographically guided selective embryo reduction in situ (by

Abstract

OBJECTIVE

To assess the efficacy and safety of primary surgical evacuation therapy

for cesarean scarpregnancy (CSP) of the first trimester and to evaluate its

possible prognostic factors

DESIGN

Retrospective consecutive cohort study

SETTING

Tertiary care university hospital

SUBJECT(S)

A cohort of patients with CSP and clear ultrasound images who underwent

primary surgical evacuation from January 2000 to December 2012

INTERVENTION(S)

Patients fulfilling the ultrasound criteria of CSP were further classified into

superficial and deep groups according to their implantation locations and

extents The final decision on the method of treatment including

methotrexate chemotherapy surgical evacuation and others was made by

the patients after consultation with the physician Pretreatment patient

SUMMARY CSP

An uncommon but potentially life-threatening

The incidence is rising as CSR is rising

Precursor of morbidly adherent placenta

Do not confuse CSP with ectopic pregnancy

Early diagnosis is important TVS is the most

effective and preferred diagnostic tool

A key first step Determine whether heart activity is

present

Aboubakr Elnashar

If heart activity is documented Counsel the patient

inform the patient of the risks of pregnancy

continuation

If continuation an additional counseling session

If termination a reliable tt that stops fetal heart beat

without delay

Avoid single tts unlikely to be effective

DampC

suction curettage

single-dose IM MTX and

Aboubakr Elnashar

Consider combination treatments best results

direct injection of MTX or Kcl into GS with TVS

Abstract

Heterotopic cesarean scar pregnancy is a rare life-threatening form of

ectopic pregnancy To provide information regarding the clinical

manifestations diagnosis management and prognosis of this condition

we reviewed all cases reported in the English literature All literature on

heterotopic cesarean scar pregnancy was retrieved by searching the

PubMed database and tracking references of the relevant literature Full

texts were reviewed and clinical manifestations diagnostic methods and

the relationship between the treatment and prognosis were summarized A

total of 14 patients with heterotopic cesarean scar pregnancies were

identified including 6 spontaneous pregnancies and 8 following in vitro

fertilization-embryo transfer Gestational ages at diagnosis ranged from 5

weeks to 8 weeks 4 days Only 5 cases presented with vaginal bleeding

and the others were asymptomatic All 14 cases were diagnosed by

transvaginal sonography One patient with no future fertility requirements

underwent pregnancy termination by methotrexate Of the remaining 13

patients who desired to preserve their intrauterine gestations 10 were

treated by sonographically guided selective embryo reduction in situ (by

Abstract

OBJECTIVE

To assess the efficacy and safety of primary surgical evacuation therapy

for cesarean scarpregnancy (CSP) of the first trimester and to evaluate its

possible prognostic factors

DESIGN

Retrospective consecutive cohort study

SETTING

Tertiary care university hospital

SUBJECT(S)

A cohort of patients with CSP and clear ultrasound images who underwent

primary surgical evacuation from January 2000 to December 2012

INTERVENTION(S)

Patients fulfilling the ultrasound criteria of CSP were further classified into

superficial and deep groups according to their implantation locations and

extents The final decision on the method of treatment including

methotrexate chemotherapy surgical evacuation and others was made by

the patients after consultation with the physician Pretreatment patient

I All are correct regarding CS scar

pregnancy (CSP) except

1 Incidence is rising

2Asymptomatic in 13 of cases

3Time of presentation is commonly 2nd trimester

4Diagnosis is missed in 14 of cases

Aboubakr Elnashar

II Sonographic criteria of CSP include

all except

1 Empty uterus with a clearly visualized

endometrium

2 Empty cervical canal

3 Gestational sac

within the anterior portion of lower uterine

segment

at site of the cesarean scar

4 Sliding organ sign is positive

Aboubakr Elnashar

III For treatment of CSP all are correct

except

1Anterior uterine wall thickness is important

2With pregnancy continuation hysterectomy

rate is 17

3Termination of the pregnancy in first

trimester is recommended

4Immediate and decisive action is

recommended

Aboubakr Elnashar

IV All are correct regarding CSP treatment

except

1 Complications are most often when single

IM Methotrexate or DampC

2 Complications are at lowest rate with

Local and US directed MTX injection with

or without additional IM MTX

3 Use of a Foley balloon catheter is not

recommended

4 laparoscopy or laparotomy with excision

of the pregnancy may be best treatment

Aboubakr Elnashar

V For follow up after treatment of CSP

all are correct except 1 5 w are required to obtain clearance of

βHCG

2 TVS is done monthly to evaluate the size

of retained products of conception

3 Avoiding pregnancy for 12 to 24 months

4 In a future pregnancy an early visit for

TVS is important

4 Suction aspiration or DampC alone or in

combination

Isolated D amp C should be avoided

1 Trophoblastic tissue and villi are implanted

within the myometrium D ampC is unlikely to expel

the GS without rupturing the uterine wall or

damaging the bladder

2 massive bleeding emergency laparotomies

3 exposed vessels in the cervical scar tissue bleed no muscle grid to contract and contain the profuse bleeding

4 Complication rate 62 (29ndash86)

bleeding complications necessitating 3rd -line tt that almost always was surgical Aboubakr Elnashar

MTX followed by suction curettage Mean blood loss 707 mL (100ndash2000 mL) tt failure 3 out of 45 despite insertion of a Foley balloon catheter If DampC is still the preferred tt of choice blood products should be available balloon catheter should be inserted in the cervix

Preoperative determination of CSP implantation depth and extent is important in selecting candidates for surgical treatment Primary single-step surgical evacuation was successful in most patients with superficial implantation but patients should be informed of the possibility of salvage interventions before undergoing surgical evacuation (Kong et

al 2014)

Abstract

Heterotopic cesarean scar pregnancy is a rare life-threatening form of

ectopic pregnancy To provide information regarding the clinical

manifestations diagnosis management and prognosis of this condition

we reviewed all cases reported in the English literature All literature on

heterotopic cesarean scar pregnancy was retrieved by searching the

PubMed database and tracking references of the relevant literature Full

texts were reviewed and clinical manifestations diagnostic methods and

the relationship between the treatment and prognosis were summarized A

total of 14 patients with heterotopic cesarean scar pregnancies were

identified including 6 spontaneous pregnancies and 8 following in vitro

fertilization-embryo transfer Gestational ages at diagnosis ranged from 5

weeks to 8 weeks 4 days Only 5 cases presented with vaginal bleeding

and the others were asymptomatic All 14 cases were diagnosed by

transvaginal sonography One patient with no future fertility requirements

underwent pregnancy termination by methotrexate Of the remaining 13

patients who desired to preserve their intrauterine gestations 10 were

treated by sonographically guided selective embryo reduction in situ (by

Outcomes of primary surgical evacuation during the first trimester in

different types of implantation in women with cesarean scar pregnancy

Author information

Abstract

OBJECTIVE

To assess the efficacy and safety of primary surgical evacuation therapy

for cesarean scarpregnancy (CSP) of the first trimester and to evaluate its

possible prognostic factors

DESIGN

Retrospective consecutive cohort study

SETTING

Tertiary care university hospital

SUBJECT(S)

A cohort of patients with CSP and clear ultrasound images who underwent

primary surgical evacuation from January 2000 to December 2012

INTERVENTION(S)

Patients fulfilling the ultrasound criteria of CSP were further classified into

superficial and deep groups according to their implantation locations and

extents The final decision on the method of treatment including

methotrexate chemotherapy surgical evacuation and others was made by

the patients after consultation with the physician Pretreatment patient

I All are correct regarding CS scar

pregnancy (CSP) except

1 Incidence is rising

2Asymptomatic in 13 of cases

3Time of presentation is commonly 2nd trimester

4Diagnosis is missed in 14 of cases

Aboubakr Elnashar

II Sonographic criteria of CSP include

all except

1 Empty uterus with a clearly visualized

endometrium

2 Empty cervical canal

3 Gestational sac

within the anterior portion of lower uterine

segment

at site of the cesarean scar

4 Sliding organ sign is positive

Aboubakr Elnashar

III For treatment of CSP all are correct

except

1Anterior uterine wall thickness is important

2With pregnancy continuation hysterectomy

rate is 17

3Termination of the pregnancy in first

trimester is recommended

4Immediate and decisive action is

recommended

Aboubakr Elnashar

IV All are correct regarding CSP treatment

except

1 Complications are most often when single

IM Methotrexate or DampC

2 Complications are at lowest rate with

Local and US directed MTX injection with

or without additional IM MTX

3 Use of a Foley balloon catheter is not

recommended

4 laparoscopy or laparotomy with excision

of the pregnancy may be best treatment

Aboubakr Elnashar

V For follow up after treatment of CSP

all are correct except 1 5 w are required to obtain clearance of

βHCG

2 TVS is done monthly to evaluate the size

of retained products of conception

3 Avoiding pregnancy for 12 to 24 months

4 In a future pregnancy an early visit for

TVS is important

Aboubakr Elnashar

Page 58: Cesarean Scar Pregnancy

4 Suction aspiration or DampC alone or in

combination

Isolated D amp C should be avoided

1 Trophoblastic tissue and villi are implanted

within the myometrium D ampC is unlikely to expel

the GS without rupturing the uterine wall or

damaging the bladder

2 massive bleeding emergency laparotomies

loss of the uterus

3 exposed vessels in the cervical scar tissue bleed no muscle grid to contract and contain the profuse bleeding

4 Complication rate 62 (29ndash86)

bleeding complications necessitating 3rd -line tt that almost always was surgical Aboubakr Elnashar

MTX followed by suction curettage Mean blood loss 707 mL (100ndash2000 mL) tt failure 3 out of 45 despite insertion of a Foley balloon catheter If DampC is still the preferred tt of choice blood products should be available balloon catheter should be inserted in the cervix

Preoperative determination of CSP implantation depth and extent is important in selecting candidates for surgical treatment Primary single-step surgical evacuation was successful in most patients with superficial implantation but patients should be informed of the possibility of salvage interventions before undergoing surgical evacuation (Kong et

al 2014)

Aboubakr Elnashar

FOLLOW-UP Placenta is implanted mostly within fibrous

tissue absorption of the GS is slow after med tt

1 9 w to obtain clearance of βHCG

2 3 months for clearance of GS on TVS

1 βHCG weekly until it is undetectable

2 TVS Monthly to evaluate the size of retained

products of conception

Aboubakr Elnashar

3 SIS in a nonpregnant patient uterine wall integrity size of the cesarean scar which may relate to the possibility of uterine scar complications in future pregnancies 4 Early TVS After CSP After CS to confirm an intrauterine location of the new gestation

Aboubakr Elnashar

5 Avoiding pregnancy No guidelines 12 to 24 months 6 Repair of scar before future pregnancies not known whether required or not Severely deficient uterine scars 10 of women who have had prior CS but CSP are much more rare

Aboubakr Elnashar

Outcomes Uneventful viable pregnancies have been reported after all modalities of conservative management Recurrence rate 5 IU pregnancy 95 spontaneous pregnancy 88 Normal pregnancy 65 Spontaneous abortion 35 higher than expected

Aboubakr Elnashar

4 PREVENTION OF CSP

1 Surgical repair of the uterine dehiscence (niche) in patients with previous CS while not pregnant

Ben Nagi et al reported on a successful surgical repair Donnez et al hysteroscopic repair Klemm et al laparoscopic-assisted vaginal repair Yalcinkaya et al robotic-assisted laparoscopic repair More research is necessary before making recommendations for such surgical tt to prevent CSP

Aboubakr Elnashar

2 Specific surgical technique single- or double-layer closure of the incision can minimize or avoid a CSP

Aboubakr Elnashar

SUMMARY CSP

An uncommon but potentially life-threatening

The incidence is rising as CSR is rising

Precursor of morbidly adherent placenta

Do not confuse CSP with ectopic pregnancy

Early diagnosis is important TVS is the most

effective and preferred diagnostic tool

A key first step Determine whether heart activity is

present

Abstract

Heterotopic cesarean scar pregnancy is a rare life-threatening form of

ectopic pregnancy To provide information regarding the clinical

manifestations diagnosis management and prognosis of this condition

we reviewed all cases reported in the English literature All literature on

heterotopic cesarean scar pregnancy was retrieved by searching the

PubMed database and tracking references of the relevant literature Full

texts were reviewed and clinical manifestations diagnostic methods and

the relationship between the treatment and prognosis were summarized A

total of 14 patients with heterotopic cesarean scar pregnancies were

identified including 6 spontaneous pregnancies and 8 following in vitro

fertilization-embryo transfer Gestational ages at diagnosis ranged from 5

weeks to 8 weeks 4 days Only 5 cases presented with vaginal bleeding

and the others were asymptomatic All 14 cases were diagnosed by

transvaginal sonography One patient with no future fertility requirements

underwent pregnancy termination by methotrexate Of the remaining 13

patients who desired to preserve their intrauterine gestations 10 were

treated by sonographically guided selective embryo reduction in situ (by

SUMMARY CSP

An uncommon but potentially life-threatening

The incidence is rising as CSR is rising

Precursor of morbidly adherent placenta

Do not confuse CSP with ectopic pregnancy

Early diagnosis is important TVS is the most

effective and preferred diagnostic tool

A key first step Determine whether heart activity is

present

Aboubakr Elnashar

If heart activity is documented Counsel the patient

inform the patient of the risks of pregnancy

continuation

If continuation an additional counseling session

If termination a reliable tt that stops fetal heart beat

without delay

Avoid single tts unlikely to be effective

DampC

suction curettage

single-dose IM MTX and

Aboubakr Elnashar

Consider combination treatments best results

direct injection of MTX or Kcl into GS with TVS

Abstract

Heterotopic cesarean scar pregnancy is a rare life-threatening form of

ectopic pregnancy To provide information regarding the clinical

manifestations diagnosis management and prognosis of this condition

we reviewed all cases reported in the English literature All literature on

heterotopic cesarean scar pregnancy was retrieved by searching the

PubMed database and tracking references of the relevant literature Full

texts were reviewed and clinical manifestations diagnostic methods and

the relationship between the treatment and prognosis were summarized A

total of 14 patients with heterotopic cesarean scar pregnancies were

identified including 6 spontaneous pregnancies and 8 following in vitro

fertilization-embryo transfer Gestational ages at diagnosis ranged from 5

weeks to 8 weeks 4 days Only 5 cases presented with vaginal bleeding

and the others were asymptomatic All 14 cases were diagnosed by

transvaginal sonography One patient with no future fertility requirements

underwent pregnancy termination by methotrexate Of the remaining 13

patients who desired to preserve their intrauterine gestations 10 were

treated by sonographically guided selective embryo reduction in situ (by

Abstract

OBJECTIVE

To assess the efficacy and safety of primary surgical evacuation therapy

for cesarean scarpregnancy (CSP) of the first trimester and to evaluate its

possible prognostic factors

DESIGN

Retrospective consecutive cohort study

SETTING

Tertiary care university hospital

SUBJECT(S)

A cohort of patients with CSP and clear ultrasound images who underwent

primary surgical evacuation from January 2000 to December 2012

INTERVENTION(S)

Patients fulfilling the ultrasound criteria of CSP were further classified into

superficial and deep groups according to their implantation locations and

extents The final decision on the method of treatment including

methotrexate chemotherapy surgical evacuation and others was made by

the patients after consultation with the physician Pretreatment patient

Abstract

Heterotopic cesarean scar pregnancy is a rare life-threatening form of

ectopic pregnancy To provide information regarding the clinical

manifestations diagnosis management and prognosis of this condition

we reviewed all cases reported in the English literature All literature on

heterotopic cesarean scar pregnancy was retrieved by searching the

PubMed database and tracking references of the relevant literature Full

texts were reviewed and clinical manifestations diagnostic methods and

the relationship between the treatment and prognosis were summarized A

total of 14 patients with heterotopic cesarean scar pregnancies were

identified including 6 spontaneous pregnancies and 8 following in vitro

fertilization-embryo transfer Gestational ages at diagnosis ranged from 5

weeks to 8 weeks 4 days Only 5 cases presented with vaginal bleeding

and the others were asymptomatic All 14 cases were diagnosed by

transvaginal sonography One patient with no future fertility requirements

underwent pregnancy termination by methotrexate Of the remaining 13

patients who desired to preserve their intrauterine gestations 10 were

treated by sonographically guided selective embryo reduction in situ (by

Abstract

OBJECTIVE

To assess the efficacy and safety of primary surgical evacuation therapy

for cesarean scarpregnancy (CSP) of the first trimester and to evaluate its

possible prognostic factors

DESIGN

Retrospective consecutive cohort study

SETTING

Tertiary care university hospital

SUBJECT(S)

A cohort of patients with CSP and clear ultrasound images who underwent

primary surgical evacuation from January 2000 to December 2012

INTERVENTION(S)

Patients fulfilling the ultrasound criteria of CSP were further classified into

superficial and deep groups according to their implantation locations and

extents The final decision on the method of treatment including

methotrexate chemotherapy surgical evacuation and others was made by

the patients after consultation with the physician Pretreatment patient
