Hepatic artery pseudoaneurysm associated with plastic biliary stent.

The increased use of interventional procedures and laparoscopic cholecystectomy in the management of hepatobiliary disorders is associated with an increased incidence of hemobilia and hepatic artery aneurysm. Here we report a case of hepatic artery pseudoaneurysm associated with a plastic biliary stent. Multiple factors were involved in the formation of the hepatic artery aneurysm (HAA) and it was successfully treated by embolization.
