title: Guglielmi detachable coil erosion into the common bile duct after embolization of iatrogenic hepatic artery pseudoaneurysm.
abstract: Intermittent hemobilia with a hepatic artery pseudoaneurysm can be seen after open or laparoscopic cholecystectomy. Transcatheter treatment of this complication is widely accepted. Although some authors suggest packing the pseudoaneurysm with coils as the treatment of choice, occluding the parent artery is the standard treatment. The authors present an unusual complication of Guglielmi detachable coil erosion into the common bile duct in a patient who presented with pancreatitis 2 years after undergoing packing of the hepatic artery pseudoaneurysm with coils. The probable causes of this rare outcome and alternative treatment options are discussed.
