Pancreaticoduodenal Artery Aneurysm Involving Papilla of Vater Successfully Treated With Endovascular Approach Despite Intraoperative Rupture

An 81-year-old woman presented with dizziness and nasal bleeding. Gastrointestinal fiberscopy (GIF) showed a pulsatile aneurysm in the duodenum, and that the orifice of the papilla of Vater was involved. Three-dimensional computed tomography imaging showed an unruptured aneurysm in the pancreatic duodenal arcade. The patient underwent an emergent endovascular embolization of the donor arteries using coils and gelatin sponge particles. She was discharged without any complications. This case was extremely rare because of the anatomic location of the unruptured pancreaticoduodenal artery aneurysm and the fact that it involved the papilla of Vater, was detected with GIF, and was successfully treated endovascularly.
