背景：本研究旨在介绍支架移植联合多层裸支架(MBS)联合技术治疗高危胸腹主动脉瘤(TAAA)的性能数据。方法：自2012年5月至2015年12月，对8例不适合手术治疗的高危胸腹主动脉瘤患者(年龄46~75岁)进行了支架植入术和MBS联合手术，并进行了平均32个月(14~58岁)的随访。结果：所有患者均获得技术成功(100%，8/8)。MBS共覆盖内脏分支24支。住院期间无并发症或死亡。随访期内无死亡及并发症发生。7例患者观察到动脉瘤缩小(最大直径缩小=5 mm)。未见动脉瘤扩张。所有患者均观察到完全的动脉瘤囊血栓形成。大多数被遮盖的侧支(23/24)被成功保留。结论：在高危手术患者中，应用支架-移植物和MBS关节技术进行全血管内修复是一种安全有效的治疗方法。预计会有更多关于这种手术的安全性和有效性的临床证据得到认可。
Background: This study aims to present the performance data on stent-graft and multilayer bare stents (MBS) joint technique in the treatment of high-risk thoracoabdominal aortic aneurysm (TAAA).Methods: From May 2012 to December 2015, 8 selective TAAA cases (ages 46-75 years) ineligible for surgical repair underwent the stent-graft and MBS joint procedure, and were closely followed up for a median of 32 months ( range 14-58). Using computed tomography images, the aneurysm size, luminal blood flow diameter, and the covered visceral branches were analyzed.Results: Technical success was achieved in all patients (100%, 8/8). Twenty-four visceral branches were covered by MBS in total. There was no complication or death during hospital stay. During follow-up period, no death or complication occurred. Aneurysm shrinkage (maximum diameter decrease >= 5 mm) was observed in 7 patients. No aneurysm expansion was observed. Total aneurysm sac thrombosis was observed in all patients. The majority of covered side branches (23/24) were successfully preserved. No visceral ischemia or bleeding complications was observed during follow-up.Conclusions: Total endovascular repair of TAAA using stent-graft and MBS joint technique may be a safe and effective alternative in high surgical risk patients. More approving clinical evidences about the safety and efficacy of this procedure are anticipated.
