Morphology of True Lumen and Surgical Outcomes of Acute Type A Aortic Dissection Repair with Superior Mesenteric Artery Malperfusion

Acute type A aortic dissection (ATAD) can cause visceral malperfusion. Central aortic repair may resolve malperfusion but some require further intervention. This study aimed to review outcomes after ATAD presenting with visceral malperfusion and to evaluate the predictive value of true lumen (TL) morphologies in preoperative computed tomography (CT) for persistent superior mesenteric artery (SMA) ischemia after central repair.
