Evolution of Visceral Arteries and Distal Aorta Following Reperfusion-First Strategy for Acute Type A Aortic Dissection With Mesenteric Malperfusion

In patients with ATAAD complicated by mesenteric malperfusion, a reperfusion-first strategy with SMA stenting may induce significant FL shrinkage in the SMA, which was most pronounced within 30 days and persisted through 3 years. The frozen elephant trunk (FET) could induce significant TL expansion in zones 4-7, which was most obvious within 30 postoperative days. The TL expansion effect of the FET was more pronounced at proximal levels (zones 4-7) than distal segments (zones 8-9).
