Background-The optimal surgical approach for management of acute type A aortic dissection remains controversial. This study aimed to assess outcomes of reoperation after acute type A dissection repair to help guide decision making around index operative strategy. Methods and Results-All aortic reoperations (n=129) at a single referral institution from August 2005 to April 2016 after prior acute type A dissection repair were reviewed. The primary outcome was 30-day or in-hospital mortality. Secondary outcomes included organ-specific morbidity and 1-and 5-year outcomes as estimated using the Kaplan-Meier method. The majority of initial reoperations were proximal aortic (aortic valve, aortic root, or ascending) or aortic arch procedures (62.5%, n=55); most initial reoperations were performed in the elective setting (83.1%, n=74). Additional nonstaged second or more reoperations were required in 21 patients (23.6%) after the initial reoperation, during a median follow-up of 2.5 years after the initial reoperation. Thirty-day or in-hospital mortality for all reoperations was 7.0% (elective: 6.3%; nonelective: 11.1%) with acceptable rates of organ-specific morbidity, given the procedural complexity. One-and 5-year overall survival after initial reoperation was 85.9% and 64.9%, respectively, with aorta-specific survival of 88% at 5 years. Conclusions-Reoperation after acute type A aortic dissection repair is associated with low rates of mortality and morbidity. These data support more limited index repair for acute type A dissection, especially for patients undergoing index repair in lower volume centers without expertise in extensive repair, because reoperations, if needed, can be performed safely in referral aortic centers.
