Total neointima implantation (patch neointima technique + triple-branched stent graft placement) has been performed in proximal aortic repair for acute type A aortic dissection (ATAAD) for more than 10 years at a center. However, there is no report on the mid-term outcomes with a control group of the surgical procedure. Consequently, the authors aimed to evaluate the safety and efficacy of this technique in this study. Patients who underwent the total neointima implantation were classified as Group A, and those who underwent the conventional aortic root reconstruction with the “sandwich” technique and the total aortic arch replacement were classified as Group B. Furthermore, the authors described the preoperative characteristics, operative data, and patient outcomes. Group A patients experienced a shorter surgery duration, lower volumes of perioperative bleeding, and fewer red blood cell transfusions. The incidence of neurological complications was significantly reduced in Group A. All patients maintained a normal range of proximal aortic sizes after surgery. Kaplan–Meier analysis revealed no significant differences between the patients in the two groups regarding cumulative mortality and the incidence of moderate-to-severe aortic insufficiency. In well-selected patients, total neointima implantation is an alternative procedure for the surgical repair of ATAAD.

全内膜植入术修复急性A型主动脉夹层的中期结果

中心在急性 A 型主动脉夹层 (ATAAD) 近端主动脉修复术中进行全新内膜植入术（补片新内膜技术 + 三分支支架植入术）已有 10 多年的历史。然而，尚无关于手术对照组的中期结果的报告。因此，作者旨在在本研究中评估该技术的安全性和有效性。将接受全内膜植入术的患者分为A组，将接受传统主动脉根部“三明治”技术重建和全主动脉弓置换术的患者分为B组。数据和患者结果。A 组患者的手术时间较短，围手术期出血量较少，红细胞输注较少。A组神经系统并发症的发生率显着降低。所有患者术后近端主动脉尺寸均保持在正常范围。Kaplan-Meier 分析显示，两组患者的累积死亡率和中重度主动脉瓣关闭不全的发生率没有显着差异。在精心挑选的患者中，全新内膜植入是 ATAAD 手术修复的替代手术。
