SURGICAL MX OF PPH
¨ Postpartum haemorrhage (PPH) has always been a major cause of maternal mortality and morbidity
¨ Fortunately, techniques for dealing with it have improved so that mortality from this cause continues to decline
¨ Some PPHs are traumatic vaginal and uterine lacerations
¨ The primary approach to dealing with these is surgical correction of the defect and the techniques required are as varied as the lacerations themselves.

SURGICAL MX OF PPH
¨ The surgical approach to the more generic causes of PPH, namely uterine atony, and the less common conditions of uterine inversion, placenta praevia and placenta accreta
¨ It should be noted that, as with many emergency surgical procedures, there are very few systematic studies of their use and non randomised trials of efficacy.
¨ Long-term follow-up data are also very few

bed 2. B Lynch brace suture
(Modifications) 3. Trans vaginal uterine
artery ligation 4. Trans abdominal uterine
artery ligation 5. Ovarian vessel ligation 6. Internal iliac artery
ligation

When DO WE opted for conservative surgery? 1. Patient relatively stable 2. Fertility is an issue : young age primid 3. Blood loss slow 4. Good support : adequate blood products,
anaesthetist, ot staff. 5. Skilled OBGYN

UTERINE ATONY
¨ Failure of the uterus to contract effectively following the delivery of the baby is the commonest cause of massive PPH
¨ Massive PPH : EBL 1500 ml ¨ Despite medical therapy, patient still bleeding then
surgical approach is required.

UTERINE COMPRESSION SUTURES
¨ If packing or balloon tamponade are ineffective, the next step is to consider direct uterine compression suturing
¨ The first suggestion of this approach was by Christopher B-Lynch, of Milton Keynes Hospital in the UK, who in 1997 published an account of 5 cases where compression of the uterus was achieved following caesarean section.

UTERINE COMPRESSION SUTURES
¨ It requires that the uterus is opened; the suture compresses the upper segment but the lower segment remains open

The B – Lynch suture compression techniques
¨ Llyod Davis or frog legged position essential ¨ The Uterus must be exteriorised ¨ Basic surgical competence required ¨ Bimanual compression to test for potential success ¨ Transverse lower segment incision made ¨ Uterine cavity checked, explored and evacuated

Sutures ?
¨ Absorbable ¨ The first paper by B-Lynch describes the use of a
70 mm round bodied hand needle with a number 2 chromic catgut suture
¨ Straight needles / curves ¨ 70 mm DEXON or VICRYL (1.0) ¨ The needle should ideally be 6 cm long so as to
exceed the combined thickness of the anterior and posterior lower segment

UTERINE COMPRESSION SUTURES
¨ If the uterus has not previously been opened (e.g. at caesarean section), a simplified suture can be inserted, such as square suturing
¨ However, there is concern that the square suture may completely occlude the blood supply to the uterine muscle within the square, leading to ischaemic necrosis and subsequent complications

Cho square haemostatic suture
¨ Multiple square sutures are used to cover the whole body of uterus using a straight 10 cm needle
¨ Probably time consuming if many suture required
¨ Uterine cavity drainage restriction –pyometra risk
¨ Risk producing multiple uterine senechiae

HAYMAN uterine compression suture
¨ Lower uterine segment or cavity not opened
¨ Uterine cavity not explored under vision
¨ Probably quicker to apply
¨ Unequal tension leads to segmented ischemia secondary to slippage of suture – shouldering with venous obstruction
¨ No data on fertility outcome

UTERINE COMPRESSION SUTURES
¨ An important principle is, therefore, to avoid sutures that apply compression both vertically and horizontally, but instead use sutures that are compressive, whether transversely, e.g. multiple horizontal sutures as described by Hackethal et al or horizontally as with the simpler loop suture inserted through the lower segment and tied at the fundus, as described by Hayman et al.

UTERINE COMPRESSION SUTURES
¨ A particular problem is dealing with bleeding from the lower segment of the uterus.
¨ This can be dealt with by square suturing, by a simple horizontal or vertical loop suture, opposing the anterior to the posterior walls of the lower segment.
¨ An ingenious variant of this, if the cervix is not fully dilated, is to invert the lower segment upon itself before suturing it, thus compressing the bleeding surfaces without occluding the uterine cavity

UTERINE COMPRESSION SUTURE
¨ Another possibility is to combine the compression suture with an intrauterine balloon. The suture must be inserted first clearly, inserting a suture after the balloon risks puncturing it.
¨ A series of five such cases was reported by Nelson and O’Brien and this method was effective in all cases without complications

UTERINE COMPRESSION SUTURE
¨ As with balloons, there are no randomised controlled trials of compression sutures but in a recent series of 11 cases where the Hayman suture was used, hysterectomy was only necessary in one patient.

UTERINE ARTERY LIGATION
¨ If use of a simple compression suture is unsuccessful, then ligation of the uterine arteries can be tried next and is often effective
¨ 90% of blood supply to uterus is from uterine arteries.
¨ Uterine artery ligation involves taking large purchases through the uterine wall to ligate the artery at the cervical isthmus above the bladder flap

UTERINE ARTERY LIGATION
¨ A suture through broad ligament to include 2-3 cm of myometrium.
¨ Suture placed about 2cm above the point where incision for lower segment caesarean section would be.
¨ Ligating ascending branch of the uterine artery and avoiding inclusion of ureter in the suture.

UTERINE ARTERY LIGATION
¨ There appear to be no consequences for future pregnancies of such ligation, presumably because a collateral circulation develops from other vessels (particularly the ovarian arteries) to compensate.

OVARIAN ARTERY LIGATION
¨ Ovarian artery directly arises from aorta ¨ Anastomosis with the uterine artery in the
region of the uterine aspect of the utero ovarian ligament

INTERNAL ILIAC ARTERY LIGATION
¨ Procedure to be learnt by ALL obstetrician recommendation of the CEMD Malaysia
¨ Bilateral ligation results in 85% reduction in pulse pressure & 50% reduction of blood flow
¨ Technically difficult initially ¨ Aware of complications

INTERNAL ILIAC ARTERY LIGATION
¨ The common, internal, and external iliac arteries must be identified clearly.
¨ The hypogastric vein, which lies deep and lateral to the artery, may be injured as instruments are passed beneath the artery, resulting in massive, potentially fatal bleeding

UTERINE ARTERY EMBOLISATION
¨ Evolved from other angiograpic embolisation techniques ( Since 30 Years)
¨ Gelatin Sponges are injected into the bleeding vessel until stasis of flow in target vessel is achieved. Acess is gained via femorals to internal iliac and subsequently the uterine arteries
