Extrahepatic pseudoaneurysms and ruptures of the hepatic artery in liver transplant recipients: endovascular management and a new iatrogenic etiology.

Purpose: To characterize extrahepatic pseudoaneurysm regarding incidence and etiology and determine the effectiveness of endovascular management.

Methods: A retrospective audit of 1,857 liver transplants in two institutions was performed (1996-2009). Recipients' demographics, clinical presentation, transplant type, biliary anastomosis, and presence of biliary endoprostheses were noted.
