Core Tip

Core tip: We report a rare case of a hemorrhagic duodenal ulcer fed by a renal artery that was successfully treated by transcatheter arterial embolization. Generally, the duodenum is fed by branches from the gastroduodenal artery or superior mesenteric artery. However, this patient had three right renal arteries, and the hemorrhage was fed by the lower branch of the right renal artery. This branch was located at the L3 vertebral level, at the same level as the horizontal portion of the duodenum. To our knowledge, this is the first reported case in which a renal artery fed a hemorrhagic duodenal ulcer.
