Transcatheter arterial embolization of the common hepatic artery for pseudoaneurysm after a laparoscopic‐assisted pancreaticoduodenectomy: A case report

Common hepatic artery pseudoaneurysm is a rare and potentially life‐threatening complication after pancreaticoduodenectomy, and the possible cause is unclear. We report a case of intraperitoneal hemorrhage after pancreaticoduodenectomy who was discharged after embolization under digital subtraction angiography. We conside that this complication may be related to iatrogenic injury. Intraperitoneal hemorrhage is one of the serious postoperative complications. We found the pseudoaneurysm of common hepatic artery after laparoscopic pancreaticoduodenectomy by digital subtraction angiography and used microcoil embolization for cure. We reviewed the procedure of laparoscopic surgery and identified several factors that might reduce postoperative bleeding.
