［摘 要］ 目的：探讨 Stanford A 型主动脉夹层（type A aortic dissection，TAAD）术后主动脉远端扩张及支架所致的新发破口
（stent induced new entry，SINE）的患者采取胸主动脉腔内血管修复术（thoracic endovascular aortic repair，TEVAR）治疗的安全性
及有效性。方法：回顾性分析南京医科大学第一附属医院2018年1月—2023年3月连续收治的27例TAAD术后支架象鼻远端

期随访结果、TEVAR 术中资料以及术后随访结果。结果：TEVAR 术后随访率 92.3%，随访时间为（35±21）个月。远期死亡 2
例，病死率7.4%，无主动脉相关死亡病例。TEVAR术后均未出现支架内漏、移位、下肢截瘫、新发透析（TEVAR术后新发肾功

全血栓化13例（68.4%），部分血栓化6例（31.6%），真腔有效打开，支架覆盖区域真腔明显增大，假腔缩小。结论：急性A型主
动脉夹层术后主动脉远端TEVAR治疗效果显著，无明显不良事件发生，是值得推广的手术方案。

［Abstract］ Objective：To investigate the safety and efficacy of thoracic endovascular aortic repair（TEVAR）in patients with stent
induced new entry（SINE）in the distal aortic dilation following surgical repair of type A aortic dissection（TAAD）. Methods：A
retrospective analysis was performed on 27 consecutive patients who underwent TEVAR for stent graft⁃induced distal aortic dilation in
Nanjing Medical University First Affiliated Hospital from January 2018 to March 2023. The intraoperative data of 27 patients with Sun’s
surgery（total aortic arch replacement plus stented elephant trunk implantation），early postoperative follow⁃up results of Sun’s surgery，

intraoperative data of 27 patients with TEVAR and postoperative follow⁃up results were statistically analyzed. Results：The follow⁃up
rate after TEVAR was 92.3%，with a mean follow⁃up time of（35±21）months. There were two cases of long⁃term mortality，resulting in a
mortality rate of 7.4%，with no deaths related to aortic complications. No stent graft leak，displacement，paraplegia，new⁃onset dialysis
（post⁃TEVAR new⁃onset renal dysfunction），intestinal ischemia，or necrosis was observed after TEVAR. Among the follow⁃up cases，

preoperative and postoperative computed tomographic angiography（CTA）of the thoracoabdominal vessels were successfully obtained
in 25 cases（92.3%）. At 6 months postoperatively，CTA revealed that the rupture was completely covered，the distal true cavity opening
of the thoracic aorta was satisfactory，and the vascular patency of the internal organs and lower limbs was 100%. 19 patients were
followed up 1 year after surgery. Among them，there were 13 cases（68.4%）of complete thrombolysis and 6 cases（31.6%）of partial
thrombolysis，the true lumen was effectively opened，the true lumen of the stent covered area was significantly enlarged，and the false
lumen was reduced. Conclusion：TEVAR treatment of distal aorta after acute type A aortic dissection is effective without significant
