A unique proposed etiology for inferior mesenteric artery aneurysm: A case report.

ABSTRACT: The etiology of large artery aneurysms has long been established as secondary to atherosclerotic disease and degenerative changes in the vessel walls. Less common, are aneurysms of the visceral arteries; the splanchnic and renal arteries. Rarer yet, are inferior mesenteric artery aneurysms, accounting for approximately 1% of visceral artery aneurysms. While causes range from inflammatory to congenital disease, a proposed etiology of proximal, solitary inferior mesenteric artery aneurysms, is correlated to the "jet disorder phenomenon," first described in a 1990 case report by Sugrue, and Hederman. This paradigm states that aneurysm formation may occur secondary to celiac and superior mesenteric artery occlusion, causing increased, and turbulent arterial flow distally. We present a case tha
