DOA # 4 CT abdomen : Finding consistent with subcapsular splenic

hematoma and hemorrhagic ascites. Transfusion 3 RBCs After blood transfusion SBP 120s. HR low 100s. Postransfusion H/H remained stable ~10/30


DOA # 5-6 H/H remained stable Mild tachycardia Serology for EBV - negative Hematology consult : No evidence of acute or chronic hematologycal

pathology Unknown cause for splenic rupture Recommends splenectomy for diagnostic purposes


DOA# 7 Laparoscopic splenectomy Blood clots in abdominal cavity, especially LUQ Subcapsular splenic hematoma Ruptured spleen Uneventful splenectomy was performed , hand

port placed for speciment removal


Postop Course POD # 2 Worsening of tachycardia to 130-140 SOB, Sat O2 low 90s, RR 20-25 BP 120-130/70-80 Stable H/H CXR – Lt pleural effusion CTA chest – no evidence of PE, worsening of lt

pleural effusion, total athelectasis LLL


Postop Course POD # 2-7 Aggressive pulmonary toilet Chest PT Improvement of respiratory status and tachycardia,

sat O2 WBC raising to max 26k then decreased and

stabilized in range 18-19k PLT progressively increased to > 1mln, ASA

initiated


POD# 9 Patient was d/c home On d/c day patient was given vaccinations: Pnemovax Hemophilus infuenzae B vaccine Neisseria meningitis vaccine


Pathology Congested spleen showing acute splenitis

and subcapsular and pericapsular hematoma associated with spontaneous rupture of spleen. Occasional abnormal and thickened hilar and intrasplenic blood vessels focally extending into the area of capsular hematoma .

Comment: In the absence of a clinical history of trauma, the splenic rupture is most likely spontaneous and due to acute splenitis. The possibility of a splenic vascular malformation cannot be entirely ruled out.


Acute splenitis Reflect septic state, neutrophilic infiltrate and

congestion within the red pulp accompanied by splenomegaly

Acute non-specific splenitis as indicator of systemic infection. Assessment of 71 autopsy cases (2) : Group A , 34 cases, cause of death sepsis Group B , 37 cases, cause f death non-

infectiousGroup A – splenitis observed in 79%Group B – no splenitis found

Atraumatic splenic rupture (1)

632 publications reporting 845 patients 30 new patients per year over 28 years 2:1 male predominance Age 18-86, mean age 45 All patients denied any trauma


Etiology

711 (84.1%) – single etiological factor 59 ( 7%) – no etiological factor was found 69 (8.2%) – two underlying pathology 6 ( 0.7%) – combination of 3 factors

There are 6 major etiological groups


Etiology1. Neoplastic2. Infectious3. Inflamatory non-infectious4. Drug related5. Mechanical6. Normal spleen


Etiology The three commonest causes of ASR:

Malignant hematological disorders 16.4%

Viral infectious disorders 14.8%

Local inflamatory /neoplastic disorders 10.9%


Diagnostic procedures (1)

Final Dx of Splenic rupture : Laparotomy 42.3% CT scan 32.4% US 18.6% Scintigraphy 0.7% Laparoscopy 0.5% Angiogram 0.3% Post-mortem 5.2%


Treatment of splenic rupture in 774 patients(1)

17% of delayed rupture and rebleeding in conservative group which required splenectomy


Multivariable logistic regression analysis of risk factorsfor atraumatic splenic rupture-related mortality in 845 patients


Multivariable logistic regression analysis of risk factorsfor atraumatic splenic rupture-related mortality in relation to926 aetiological factors


Overwhelming postsplenectomy sepsis(OPSS)

Reduced post-splenectomy levels of opsonins, splenic tuftsin, and immunoglobulin (IgM)

Decrease the body’s ability to clear encapsulated organisms: Streptococcus pneumoniae Haemophilus influenzae type b Neisseria meningitidis.



Incidence of OPSS is estimated to be 0.05% to 2%

It may develop immediately or as late as 65 years postsplenectomy

Mortality is significant and reported to be as high as 50%

As 50 to 90% of OPSS infections are secondary to Streptococcus pneumoniae infection



Vaccination, to impart immunity against encapsulated organisms, is commonly performed

No Class I or Class II data to support efficacy vaccination

Pneumococcal vaccine results in the highest antibody titers when administered 14 days postsplenectomy ( class 1 studies16-17)


Current Center forDisease Control (CDC) recommendations for post-splenectomy vaccinations


Summary 93% of ASR associated with underlying spleen

pathology – “atraumatic pathological rupture” 7% there is no underlying pathology – “idiopatic

atraumatic splenic rupture” ASR of unknown etiology should undergo total

splenectomy for diagnostic purpose
