Surgical treatment of extrahepatic portal vein aneurysm: A case report and review of the literature

A portal vein aneurysm, first reported by Barzilai and Kleckner in 1956, is a rare clinical entity caused by portal hypertension or the malformation of veins. The frequent application of radiological imaging for diagnosis and screening of abdominal disorders accounts for the increasing number of case reports over the past 10 years; however, fewer than 60 cases have been reported in the English language literature to date. Herein we report a woman with an extrahepatic portal vein aneurysm, and present a review of literature relating to etiology, clinical significance and management strategies.
