Hemorrhage after pancreaticobiliary surgery is an infrequent but fatal complication. It is primarily caused by rupture of the pseudoaneurysm, and treatment options include endovascular coil embolization or endovascular stent-graft placement. Herein, we report a case of migration of an arterial stent-graft that was placed in the common hepatic artery to treat pseudoaneurysm after pylorus-preserving pancreaticoduodenectomy. The stent-graft migrated to the jejunum and was eventually excreted from the body.
