Objective: Our objective was to analyze the long term survival of patient operated on for acute type A aortic dissection. Methods: Between 1990 and 2010, 226 patients underwent emergency surgical operation for acute type A aortic dissection. We have followed the long-term outcomes. Results: 144 patients were operated on with a supracommissural replacement of the ascending aorta (SCR) and 82 with an aortic root surgery (ARS, including 77 Bentall procedures and 5 Tirone David operations). Aortic cross-clamp was longer in ARS group (150.8 vs. 103.6 min, p < 0.0001). Overall in-hospital mortality was lower in ARS group (20% vs. 34%, p 0.03). Median follow-up was 11.6 years. 10-year survival was higher in ARS group (85.7% vs. 65.9%, p 0.03) and 10-year freedom from aortic root reoperation was significantly lower in ARS group (93.4% vs. 82.9%, p 0.02). In a multivariate analysis aortic root surgery was an independent protective factor for proximal reoperations OR 0.393, CI 95% [0.206-0.748], p = 0.005. Conclusions: Our study suggests that complete aortic root replacement in type A aortic dissection does not burden short-term outcomes, improves long-term survivals and decreases the rate of late reoperation. Whether this approach has to be preferred in younger patient has to be demonstrated in further studies. (C) 2015 Elsevier Ireland Ltd. All rights reserved.
