Multiple splenic artery aneurysms in EHPVO patients: A case series

Abstract

The most common visceral artery aneurysm is splenic artery aneurysm. Splenic artery aneurysm (SAA) occurs predominantly in multiparous women. The main risk factors are female gender, multiple pregnancies, atherosclerosis, hypertension, cirrhosis, and portal hypertension. SAAs are usually asymptomatic. Giant SAAs are more likely to cause symptoms and result in life-threatening complications. Multiple splenic artery aneurysms are very rare and only a few cases are reported. Available methods for the treatment of SAAs include endovascular techniques, open and laparoscopic surgical approaches. We present three cases of multiple splenic artery aneurysms diagnosed incidentally in patients with extrahepatic portal vein obstruction. All patients were treated simultaneously with aneurysm excision, distal pancreatosplenectomy and esophagogastric devascularization procedure. There was minimal morbidity and no mortality in our series.
