Abstract

Type A acute aortic dissection (AAAD), involving the ascending aorta, is one of life-threatening disorders. Emergent surgery, such as graft replacement of the aortic root, ascending aorta, aortic arch, or these combinations, is routinely performed to avoid sudden death due to free rupture, cardiac tamponade, or coronary obstruction. Even though appropriate surgery is immediately completed, however, operative mortality remains high, between 15% and 30%. Furthermore, mesenteric malperfusion, bringing about enteric ischemia, occurs unusually in AAAD with far and away higher mortality. In the present article, we reviewed contemporary evidence regarding incidence, mortality, and treatment of mesenteric malperfusion complicated with AAAD. The incidence and early mortality rate of mesenteric malperfusion complicated with AAAD was 4% and 68%, respectively. Patients with mesenteric malperfusion had a 9.7-fold risk of mortality relative to those without it. Evidence regarding optimal treatment of mesenteric malperfusion complicated with AAAD is very limited.
