Abstract:
Objective:To evaluate the safety and efficacy of the neoadventitia technique for root repair in acute type A aortic dissection(ATAAD).Methods:From January 2019 to February 2022, a total of 94 patients with ATAAD who underwent surgical treatment in Beijing Anzhen Hospital were retrospectively analyzed. According to the different treatment methods for the aortic root, the patients were divided into the neoadventitia technique group(58 cases) and the Bentall group(36 cases). The perioperative data and postoperative follow-up results of the two groups were compared, and the efficacy of the new adventitia technique in acute type A aortic dissection was analyzed.Results:There were no intraoperative deaths. The 30-day mortality was 3.4% and 5.6% in the neoadventitia group and Bentall group, respectively ( P=0.636). The cardiopulmonary bypass time[(154.3±29.8)min, P<0.001] and aortic clamp time[(94.7±20.6)min, P<0.001)]were significantly shorter in the neoadventitia group, compared with the Bentall group. Aortic regurgitation was significantly improved after the operation (0.33±0.50 vs. 1.02±0.80, P<0.001). No aortic root-related secondary intervention occurred during follow-up. There was no significant difference in mortality between the two groups( P=0.248). Conclusion:Neoadventitia root repair is a safe and feasible method for the treatment of ATAAD, which has good short-term and mid-term efficacy.
