She had a history of Factor V Leiden and unprovoked pulmonary embolism (PE) and was on lifelong warfarin. The patient was found to have a widened mediastinum and a small left-sided pleural effusion on chest X-ray, leading to CT aortogram to assess for aortic pathology. While in the CT scanner, she experienced an acute deterioration and went into shock. The initial diagnosis was anaphylactic reaction to the contrast agent, but the CT images revealed an active bleeding in the left upper quadrant, possibly of splenic origin. The patient was stabilized with aggressive resuscitation measures and transferred to a referral hospital for urgent surgery. The surgery revealed a ruptured splenic artery aneurysm (SAA), and the patient was taken to the intensive care unit (ICU) for further management. However, she developed a large infarct in the left occipital lobe and passed away after six days. The case highlights the significance of recognizing the symptoms and signs of SAA and then taking a multidisciplinary approach in managing SAA patients, particularly those with hypercoagulability (Graphic 1).展开更多

A case of a 50-year-old multiparous female who developed suddenly portal hypertension due to SAVF formation is presented. The patient suffered from repeated episodes of haematemesis and melaena during the past twelve days and thus was emergently admitted to hospital for management. Clinical and laboratory investigations established the diagnosis of portal hypertension in the absence of liver parenchymal disease. Endoscopy revealed multiple esophageal bleeding varices. Abdominal computed tomography （CT） and transfemoral celiac arteriography documented the presence of a tortuous and aneurysmatic splenic artery and premature filling of an enlarged splenic vein, findings highly suggestive of an SAVF. The aforementioned vascular abnormality was successfully treated with percutaneous transcatheter embolization. Neither recurrence nor other complications were observed.展开更多

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
