A 70-year-old man with chronic renal failure who was undergoing hemodialysis was referred to our hospital for epigastralgia. Computed tomography (CT) revealed a common bile duct stone. Endoscopic sphincterotomy (EST) was performed to remove the stone. Four days after EST, he developed shock with melena. CT revealed an aneurysm in the papilla of Vater. Angiography demonstrated rupture of aneurysm of the posterior superior pancreaticoduodenal (PSPD) artery. Selective transcatheter arterial embolization (TAE) with intravascular microcoils was performed and hemostasis was achieved. Aneurysm of the PSPD artery following EST is very rare, and TAE is one of the effective therapeutic maneuvers for post-EST hemorrhage.
