主动脉覆膜支架腔内修复Stanford B型主动脉夹层

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。

Thoracic Endovascular Aortic Repairing Treatment with Stent-Graft for Stanford Type B Aortic Dissection

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 data.To analyze surgical methods,perioperative complications and short-term results.43 cases were followed up for one to thirties months.Results All 51 patients’immediate surgery were successed.One patient died within the perioperative period.The serious postoperative complications included typeⅠendoleak (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=1).3 cases had died in follow-up period,which was concerned with 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.Short-term curative effect is good,but the further follow-up is necessary to evaluate its long-term effectives.
