Infrarenal Origin of the Superior Mesenteric Artery: Implications in Endovascular Repair of Abdominal Aortic Aneurysm

Abstract

Endovascular aneurysm repair (EVAR) has become the preferred modality for the treatment of infrarenal abdominal aortic aneurysms (AAAs). A variety of anatomic factors must be considered when planning EVAR, including the relationship of the visceral arteries to the aneurysmal segment of the aorta. This report describes 2 patients with infrarenal AAA in whom the superior mesenteric artery was the most caudal visceral vessel, originating inferior to the renal arteries.
