A rare cause of digestive hemorrhage: an aneurysm of the superior pancreaticoduodenal artery rupturing into the duodenal stump of a Billroth II partial gastrectomy.

We report herein a case of an iatrogenic superior pancreaticoduodenal arterial aneurysm which ruptured into the duodenal stump of a Billroth II partial gastrectomy. Superselective angiography was used for the diagnosis, and successful embolization performed nonoperatively. A review of the literature revealed both the etiology and site of rupture in this case to be extremely uncommon.
