Rupture of the anterior superior pancreaticoduodenal artery aneurysm after endoscopic removal of common bile duct stone: a case report

Abstract

A 74-year-old man visited our hospital with a complaint of epigastralgia and jaundice. Enhanced abdominal computed tomography revealed a small bile duct stone. Endoscopic removal of a common bile duct stone was performed. On the evening of the next day, he became unconsciousness and went into a state of shock with hypotension. Angiography revealed an aneurysm in the anterior superior pancreaticoduodenal artery (ASPD). We diagnosed a ruptured pancreaticoduodenal artery aneurysm (PDAA) and performed selective transcatheter arterial embolization with intravascular microcoils. We report a case of rupture of the ASPD artery aneurysm after endoscopic removal of common bile duct stone. We also review 105 cases reports on PDAA reported in Japanese literature.
