目的:回顾性分析双马甲包裹根部加固重建方法近端修复急性A型主动脉夹层的近期疗效。方法:2018年1月到2019年10月，455例急性Stanford A型主动脉夹层患者接受了手术治疗。其中，双马甲包裹根部加固重建(DJW)343例(其中11例同时行瓣叶悬吊)，Bentall手术81例，Wheat手术15例，未处理根部12例， David手术4例。对比分析接受两种不同手术方式的患者资料，比较两组患者围手术期指标和术后近期生存情况。结果:全部患者无手术死亡，DJW组和Bentall组术后30天死亡比例分别为10.5%和7.4%(n P＝0.403)；体外循环(218.8±68.4)min对(240.2±59.8)min，n P＝0.011；主动脉阻断(150.6±47.9)min对(181.3±45.6)min，n P＝0.000。手术时间和深低温停循环时间两组差异无统计学意义。所有患者随访(11.7±6.4)个月，随访期间9例死亡，DJW组7例，Bentall组2例，死因均与主动脉根部无关。DJW法术后主动脉瓣反流度为0.7±0.5，较术前显著降低(n P＝0.000)。n 结论:DJW法是一种安全、有效的急性A型主动脉夹层根部修复方法，早期疗效良好。“,”Objective:To introduce a new method of root reconstruction for proximal repair of acute type A aortic dissection, and to retrospectively analyze its short-term efficacy.Methods:From January 2018 to October 2019, a total of 455 patients with acute Stanford type A aortic dissection received surgical treatment. Among them, 343 patients underwent double-jacket-wrapping(DJW) root reinforcement(11 patients underwent leaflet suspension), 81 patients underwent Bentall surgery, 15 Wheat operations, 12 untreated roots, and 4 David operations. Compared 343 patients who underwent double-jacket-wrapping root reconstruction and 81 patients who underwent Bentall surgery. The perioperative indicators and short-term survival of the two groups were compared.Results:No patients died intraoperatively. The 30-day mortality rate in the DJW group and the Bentall group were 10.5% and 7.4%, respectively(n P=0.403); cardiopulmonary bypass time were(218.8±68.4) min and(240.2 ± 59.8), n P=0.011; aortic clamp time were(150.6 ± 47.9) min and(181.3 ±45.6)min, n P=0.000. There was no difference between the operation time and the deep hypothermia circulatory time between the two groups. The mean follow-up was(11.7±6.4) months. Seven and two follow-up deaths occurred in the DJW group and the Bentall group, respectively, and the cause of death was not related to the aortic root. The degree of aortic regurgitation after DJW was 0.7±0.5, which was significantly lower than that before surgery(n P=0.000).n Conclusion:Compared with Bentall surgery, DJW method is a safe and effective method for the repair of acute type A aortic dissection roots, which can obtain good perioperative and early curative effects.
