We experienced a cured case of a ruptured pseudoaneurysm of the right hepatic artery after surgery of the biliary tract. A 73–year–old man was admitted to our hospital due to sense of chest oppression and was diagnosed as having a choledochal cyst (Todani Ia type) with gallbladder cancer based on several radiological examinations. He underwent an extended cholecystectomy, bile duct resection and choledochojejunostomy and was discharged from our hospital on postoperative day (POD) 10 with no complications. However, he was readmitted to our hospital with hematemesis on POD 24. Emergency enhanced abdominal CT was carried out on him for shock–related vital signs and revealed a pseudoaneurysm of the ligated gallbladder artery in the right hepatic artery with extravasation of contrast medium at the site of the choledochojejunostomy. An emergency angiography was performed for transcatheter artery embolization (TAE) with microcoils and showed the pseudoaneurysm. TAE was completed and the pseudoaneurysm was not detected by arteriography after the TAE. Angio CT could not identify the pseudoaneurysm or any extravasation of contrast medium on nine days after the TAE （POD 33）. Eventually, he was healthily discharged from our hospital 12 days after the TAE (POD 36).
