title: Hepatic artery pseudoaneurysm following laparoscopic cholecystectomy.
abstract: The authors describe a hepatic pseudoaneurysm following laparoscopic cholecystectomy in a child. It arose from a hepatic artery that was ligated during surgery and was supplied by collaterals from the superior right branch. Because of the risk of hepatic infarction and recanalization of the pseudoaneurysm by new collaterals, the authors decided not to occlude the superior right branch, but to embolize the aneurysm itself with cyanoacrylate. Since the intra-arterial approach was not feasible, a transhepatic puncture was successfully performed.
