Hemorrhagic complications are usually manifestations of the progress of severe pancreatitis. In major arterial hemorrhage resulting from pancreatic inflammatory disease, visceral angiography is valuable in localizing the site of bleeding, and hemostasis can be achieved by transcatheter arterial embolization. Successful transcatheter embolization of bleeding in the anterior superior pancreaticoduodenal artery using ethylene-vinyl alcohol copolymer (Onyx) was performed in a 38-year-old woman with acute biliary necrotic-hemorrhagic pancreatitis.
