腔内隔绝术治疗Stanford B型主动脉夹层46例临床分析

目的 评价腔内隔绝术治疗Stanford B型主动脉夹层的临床疗效和安全性.方法 回顾性分析46例StanfordB型主动脉夹层行主动脉腔内隔绝术治疗患者的临床资料,所有患者均经股动脉切开置入覆膜支架封堵胸主动脉破裂口,分析手术方法、手术结果、术后并发症及随访结果.结果 46例患者手术均获成功,术后住院5～20（12.9±3.4）d,术中2例出现残余内瘘,经重复扩张后内瘘减轻.随访2d至5.1年,平均36个月,随访期间有1例患者术后出现腔隙性脑梗死,1例患者出院后2d死亡,其余患者均未再出现主动脉夹层及截瘫等严重并发症.结论 腔内隔绝术治疗Stanford B型主动脉夹层的院内及中期疗效满意,明显改善患者的生存率和生活质量.

Clinical analysis of endovascular graft exclusion for 46 patients with Stanford type B aortic dissection

Objective To analysis the efficacy and safety of endovascular graft exclusion for patients with Stanford type B aortic dissection.Methods The clinical data of 46 patients with Stanford type B aortic dissection who received endovascular graft exclusion were analyzed retrospectively.The stents were inserted from the femoral artery to exclude the tear of dissection,and all operation were peformed under digital subtraction angiography （DSA）.The operative technique,outcome and complications were observed.Results The stents were successfully performed in all patients.The length of stay in hospital time after operation was 5-20 （12.9 ± 3.4） d.Endo-leak occurred in 2 patients and relieved after re-expanding.Followed up for 2 d to 5.1 years,average 36 months,1 patient got lacunar infarction and 1 patient died after leaving hospital 2 d.The others were free from the serious complications such as aortic dissection and paraplegia.Conclusion Endovascular graft exclusion is safe and effective for the treatment of Stanford type B aortic dissection in hospital and mid-term,and can significantly improve the survival rate and quality of life.
