A case of pseudoaneurysm ruptured into gallbladder and successfully treated with arterial embolization

Abstract

A 79-year-old man was admitted with hematemesis. Emergency upper gastrointestinal tract endoscopy revealed bleeding from the papilla of Vater. Computed tomography showed cholecystitis with a gallstone and a hematoma in the gallbladder. Angiography demonstrated a pseudoaneurysm of the anterior branch of the right hepatic artery. Emergency selective transcatheter arterial embolization (TAE) was performed, with intravascular microcoils, and complete occlusion of the pseudoaneurysm was achieved. This case shows embolization is effective in the treatment of pseudoaneurysm rupturing in the gallbladder.
