title: Ruptured hepatic artery aneurysm with hepatic artery-to-portal vein fistula. Preservation of portal flow by autogenous vein reconstruction.
abstract: Hepatic artery aneurysms are uncommon lesions that have varied clinical presentations. Rupture into the portal vein has occasionally been reported, as has associated gastrointestinal bleeding. A case is described in which an unusually large hepatic artery aneurysm ruptured into the portal vein, destroying a major portion of its wall. Reconstruction was accomplished successfully by use of an autogenous saphenous vein patch with preservation of hepatopetal portal flow.
