Portal vein pseudoaneurysm with portoenteric fistula: An unusual cause for massive gastrointestinal hemorrhage

Abstract

Pancreaticoduodenectomy (Whipple's procedure) is a commonly performed procedure for the treatment of pancreatic malignancies. Postoperative bleeding from adjacent arteries is a well-established complication of this procedure. This article describes an unusual case of massive gastrointestinal bleeding following pancreaticoduodenectomy due to the development of a portal vein pseudoaneurysm with a portoenteric fistula. The diagnosis was confirmed with multidetector computed tomography angiography; the different endovascular treatment options are discussed. Copyright © 2007 by Thieme Medical Publishers, Inc.
