Double-barrel stenting for endovascular repair of a superior mesenteric artery dissecting aneurysm

The patient was a 58-year-old man with a history of hypertension who had incidentally been found to have a 2.7-cm dissecting fusiform superior mesenteric artery aneurysm involving a long segment of a proximal to distal superior mesenteric artery. Double-lumen anatomy was present, 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 to undergo endovascular repair using double-barrel stenting with self-expanding and balloon-expandable covered stents, as described. Computed tomography angiography after 1 year demonstrated patent stents.
