Multiple aneurysms of the visceral arteries with migrating vascular bruit on postural change: a case report.

Multiple aneurysms of the gastroepiploic artery and the ileocecal branch of the superior mesenteric artery were found in a 68-year-old male patient by angiography. The patient presented with one-hour postprandial epigastric pain of 10 years duration. Abdominal bruit was auscultated at the two different sites, one of which shifted downwards upon upright position. From the freely movable nature of the great omentum, this bruit, migrating upon postural change, was most likely from the gastroepiploic artery aneurysms. The aneurysms were excised and the abdominal bruit disappeared. The etiology of the aneurysms was suggested to be arterial fibrodysplasia histologically. From this experience, it was stressed that postural change should be added to a routine physical examination to rule out an aneurysm from the freely movable great omentum.
