Objective To investigate the clinical efficacy of thoracic endovascular aortic repairing(TEVAR) treatment with stent-graft for Stanford type B aortic dissection. Methods TEVAR for type B aortic dissection had been performed in 51 patients with clinical daia. 'TVs analyze surgical methods, perioperative complicalions and short-term results. 43 cases were followed up for one lo thirties months. Results All 51 patients immediate surgery were surceased. One patient died within the perioperalive period. The serious postoperative complications included type I endoleak (n=8), pulmonary infection (n=3), arterial embolism of lower limb (n=2), retrograde type A aortic dissection (RTAD) (n=1), acute renal failure(ARF)(n=l). 3 cases had died in follow-up period, which was concerned witli aortic dissection. Conclusions TEVAR is a safe and effective treatment for Stanford type B aortic dissection, however, the possible occurrence of life-threatening complications should not be ignored. Shor!.-!.erm curative effect is good, but I he further follow-up is necessary lo evaluate its long-term effectives.%目的:探讨主动脉覆膜支架腔内修复术治疗Stanford B型主动脉夹层的临床疗效.方法:回顾性分析51例主动脉夹层行腔内修复术患者的临床资料,分析其手术方法、围手术期并发症及近期疗效.随访43例,随访时间1～30个月.结果:51例手术即刻全部成功,围手术期死亡1例.手术后并发症Ⅰ型内漏8例,肺部感染3例,下肢动脉栓塞2例,逆行性A型夹层1例,急性肾功能衰竭1例.随访期内共有3例患者死亡,死亡原因与夹层本身有关.结论:腔内修复术治疗B型主动脉夹层安全、有效,但并发症不容忽视.术后近期疗效较好,远期疗效仍待随访.
