摘　　要：BACKGROUND Pseudoaneurysms of the hepatic artery or its branches have been reported following abdominal trauma,iatrogenic injury at the time of many operations such as percutaneous transhepatic biliary drainage and cholecystectomy.Hepatic artery pseudoaneurysms after endoscopic retrograde cholangiopancreatography(ERCP)are uncommon and potentially life threatening and should be identified and treated rapidly.CASE SUMMARY We report a case of intra-abdominal hemorrhage secondary to a left hepatic artery pseudoaneurysm resulting from guide wire injury at ERCP.The patient primary diagnosis was acute biliary pancreatitis with cholangitis,he underwent ERCP on the third day of admission.During ERCP,the left intrahepatic bile duct was cannulated three times.Over the sixth day,Contrast enhanced computed tomography scan demonstrated left hepatic lobe contusion and a pseudoaneurysm formation.The patient was successfully treated with the embolization of a small branch of left hepatic artery angiographically.CONCLUSION The common complications of ERCP are pancreatitis,bleeding and perforation.False aneurysms occur as a result of damage to the wall of an artery.As far as we know,it is rare complication has been reported following ERCP.We advise urgent referral for angiographic embolization in this situation to avoid aneurysm rupture.
