Pancreaticoduodenal artery aneurysm with celiac trunk occlusion. Report of a case.

A case of superior mesenteric artery branch aneurysm is described. A 43-year-old female patient was hospitalized after the incidental discovery of a low echogenic mass next to the superior mesenteric artery trunk. A selective superior mesenteric arteriography confirmed aneurysms of the inferior pancreaticoduodenal artery and an aortogram demonstrated occlusion of the celiac trunk. Bypass between the abdominal aorta and the common hepatic artery and resection of aneurysms were performed. The possible etiology and operative procedure are discussed.
