“…In utero diagnosis of a portal vein aneurysm is further evidence of the congenital theory [4,7]. On the other hand, the acquired lesions are secondary to chronic liver disease, portal hypertension, trauma, and pancreatitis [1][2][3]5]. There is no apparent gender predominance in patients with portal vein aneurysms [2,3].…”

“…The congenital origin is supported by the presence of the aneurysms in children and young adults without portal hypertension and liver disorder [1][2][3][4][5][6][7]. A proposed pathogenesis of this congenital form is congenital weakness of the venous wall.…”

“…Complications of EPVA include thrombosis, rupture, portosystemic shunts, and compression of adjacent viscera. Thrombosis may occur in 30% of patients with portal vein aneurysms, probably due to stagnant flow within the aneurysm [5]. Until now, 13 cases with thrombosed EPVA have been reported [5].…”

“…In addition, obstruction of the portal vein and the splenic vein with multiple small collateral veins was better delineated on CT than on US. Angiography should be restricted to patients who require an interventional procedure [3,5]. Color Doppler US is the preferred imaging technique for follow-up.…”

Extrahepatic portal vein aneurysm is a rare condition. We report six patients with extrahepatic portal vein aneurysm, four of whom were surgically treated. In addition, a review of the literature was performed to examine natural history, management, and outcomes regarding portal vein aneurysm. Patients seen at our institution with extrahepatic portal vein aneurysm greater than 1.9 cm in diameter were reviewed (1998 to 2006). There were five females and one male; median age was 66.5 (30-77). Computed tomography (CT) scan was utilized for diagnosis in all cases. The median diameter of the aneurysm was 4.7 cm (2.7-6.0). Indications for surgery included gallstone pancreatitis, mass effect on the adjacent duodenum, a peripancreatic mass, and liver cirrhosis. Three patients underwent aneurysm resection, and one patient had an orthotropic liver transplant. Two patients were managed with observation. The median follow-up from first presentation and surgery was 50 months (9-181) and 5 months (2-73), respectively. At last follow-up, five patients were alive with radiologically proven portal vein patency. One patient died 2 months after liver transplantation. There was no case of aneurysmal rupture. One patient had intramural thrombus at presentation that resolved with conservative treatment. This report suggests that symptomatic aneurysms can be safely resected with excellent patency.

The most frequent location of visceral venous aneurysms is the portal venous system. They are often associated with cirrhosis and portal hypertension. They may be asymptomatic or present with abdominal pain and other symptoms. Watchful waiting is an appropriate treatment, except when complications occur. Most common complications are aneurysm thrombosis and rupture. Other visceral venous aneurysms are extremely rare.
