Double Barrel Stenting for Endovascular Repair of a Superior Mesenteric Artery Dissecting Aneurysm

Abstract The patient is a 58-year-old man with a history of hypertension who was incidentally found to have a 2.7 cm dissecting fusiform superior mesenteric artery aneurysm involving a long segment of proximal to distal superior mesenteric artery. There was a double lumen anatomy with the true lumen perfusing the proximal and mid-small bowel and the false lumen perfusing the distal small bowel and the ileocolic artery. The patient elected for an endovascular repair which was performed utilizing double-barrel stenting with self-expanding and balloon-expandable covered stents as described. Computed tomography angiography (CTA) after 1 year demonstrated patent stents.
