title: Embolization of an hepatic artery pseudoaneurysm following laparoscopic cholecystectomy.
abstract: Vascular injuries during laparoscopic cholecystectomy can occur in an analogous fashion to biliary injuries, with potential laceration, transection, and occlusion of blood vessels. A patient presented with symptomatic hemobilia 1 month following laparoscopic cholecystectomy and was found to have a right hepatic artery pseudoaneurysm which communicated with the common bile duct. This was successfully embolized with several embolic agents, resulting in rapid resolution of all signs and symptoms. The patient has been free of symptoms during a follow-up period of 1 year. A brief discussion of hepatic artery pseudoaneurysms is presented.
