While portal hypertension is an important etiological factor, the majority of reported cases are secondary to cirrhosis of the liver. We report three cases of splenic artery aneurysms associated with extrahepatic portal vein obstruction and discuss their management. METHODS: The records of three patients of splenic artery aneurysm associated with extrahepatic portal vein obstruction managed from 2003 to 2010 were reviewed retrospectively. The clinical presentation, surgical treatment and outcome were analyzed. RESULTS: The aneurysm was >3 cm in all patients. The clinical symptoms were secondary to extrahepatic portal vein obstruction (hematemesis in two, portal biliopathy in two) while the aneurysm was asymptomatic. Doppler ultrasound demonstrated aneurysms in all patients. A proximal splenorenal shunt was performed in two patients with excision of the aneurysm in one patient and ligation of the aneurysm in another one. The third patient had the splenic vein replaced by collaterals and hence underwent splenectomy with aneurysmectomy. All patients had an uneventful post-operative course. CONCLUSIONS: Splenic artery aneurysms are associated with extrahepatic portal vein obstruction. Surgery is the mainstay of treatment. Although technically difficult, it can be safely performed in an experienced center with minimal morbidity and good outcome.展开更多

A majority of these patients are asymptomatic, but oc- casionally there is symptomatic biliary obstruction, and cholangitis and choledocholithiasis. Objective: To explore the principles of diagnosis and treatment of portal biliopathy. Data sources: To review the literature of portal bili- opathy. Conclusions: Endoscopic sphincterotomy, stone ex- traction and supportive drainage could effectively re- lieve cholangitis when jaundice is associated with common bile duct stones. Definitive decompressive portal-system vein shunting operation and choledo- cho-jejunostomy are sometimes required when biliary obstruction is recurrent and progressive.展开更多
