Hybrid Approach to Repair Type A Aortic Dissection: Combined Endovascular Superior Mesenteric Artery Stenting and Bentall Procedure

A Stanford Type A aortic dissection is a life-threatening surgical emergency that requires emergent surgery. The mortality after repair is high especially if the aortic dissection is complicated by visceral or peripheral malperfusion. We describe a case of a male patient who presented with an aortic dissection involving the ascending aorta, aortic arch, descending thoracic aorta, and the abdominal aorta down to the iliac bifurcation. The dissection also involved the visceral and renal arteries with evidence of superior mesenteric artery (SMA) occlusion. Successful outcome was achieved by endovascular stenting of the patient's SMA, followed by a Bentall procedure. To the best of our knowledge this is the first case report in the English literature of SMA stenting followed by a Bentall procedure to treat acute Type A aortic dissection complicated by SMA occlusion.
