OBJECTIVE: For patients with type A aortic dissection complicated by mesenteric malperfusion syndrome, some centers advocate a nontraditional approach based on up-front endovascular intervention and delayed open repair. However, the efficacy of this strategy cannot be understood without first understanding outcomes of the traditional open-first strategy in the same select patient population eligible for delayed repair, applying modern techniques of hybrid aortic surgery.
METHODS: Patients with acute type A aortic dissection and mesenteric malperfusion syndrome were queried from a single institution. Those presenting with aortic rupture, tamponade, or cardiogenic shock (ineligible for delayed repair) were excluded. Patients were managed with immediate open aortic repair. Short-term and long-term outcomes are reported.
RESULTS: A total of 1228 patients were treated for acute type A dissection in the study period, of whom 77 were included in the mesenteric malperfusion syndrome cohort. In-hospital mortality was 29% compared with 39% in an identically selected mesenteric malperfusion syndrome population undergoing delayed repair reported previously. Among patients with mesenteric malperfusion syndrome, 32% underwent additional procedures addressing distal malperfusion in a hybrid operating room during or after open repair. Concomitant proximal malperfusion (coronary, cerebral, or upper extremity) was common in the mesenteric malperfusion syndrome cohort, present in 35% of cases. Although early mortality was greater in the mesenteric malperfusion syndrome cohort compared with all acute type A dissections, 10-year survival among those discharged alive was similar (65% vs 59%, P = .18).
CONCLUSIONS: The traditional open-first repair strategy performs equal to or better than the delayed repair strategy for patients with mesenteric malperfusion syndrome eligible for delayed repair.
