Embolotherapy of massive duodenal hemorrhage.

Eleven patients with massive duodenal hemorrhage were treated by emergent embolization. Bleeding originated from duodenal ulcer in three patients, from duodenal tumor in one, from ruptured pancreaticoduodenal artery pseudoaneurysm in three, and from ruptured gastroduodenal artery pseudoaneurysm in four. Complete hemostasis was obtained immediately after embolotherapy in all cases. Three of these patients died during the hospitalization period, one of whom from duodenal infarction and pancreas necrosis induced by embolization. In three patients with duodenal ulcer, complete hemostasis was obtained only by the gastroduodenal artery embolization with Gelfoam particles. Seven patients with pseudoaneurysms of the gastroduodenal artery or its branches required not only blockage of blood flow from the celiac artery but also the superior mesenteric artery for complete hemostasis. Therefore, in patients presenting with duodenal hemorrhage, the possibility of dual blood supply to the duodenum should be considered. Emergent embolization represents a useful alternative to surgery for massive duodenal hemorrhage, but it carries a risk of complications in patients with previous gastroduodenal surgery or significant visceral atherosclerosis.
