title: Embolization of proper hepatic artery pseudoaneurysm complicating choledochoscopic laser therapy.
abstract: Biliary papillomatosis is a rare disease characterized by multiple papillary proliferation of the epithelial cell of the bile duct. Because it has a tendency to be recurrent, the treatment strategy is choledochoscopic laser therapy. A patient with biliary papillomatosis treated by choledochoscopic laser therapy, which was complicated by massive haemobilia and shock, is presented. An intrahepatic artery pseudoaneurysm was diagnosed on angiography. A coexisting occlusion necessitated a superselective embolization of the pseudoaneurysm in order to avoid devascularization of the left lobe of the liver.
