覆膜支架与裸支架腔内介入治疗主髂动脉闭塞的疗效对比

Clinical effect of covered stent versus bare stent on endovascular interventional treatment of aortoiliac occlusive disease

目的:分析覆膜支架与裸支架腔内介入治疗主髂动脉闭塞的临床疗效对比。方法:分析2014年1月至2016年12月我院使用覆膜支架腔内介入治疗主髂动脉闭塞的患者20例,与同期25例采用裸支架的患者做对比,分析两者的一期通畅率、二期通畅率及临床疗效。结果:45例患者均成功实行腔内介入治疗,随访5~39个月,平均(14±8)个月,覆膜支架组的一期通畅率为95%,二期通畅率为100%;裸支架组一期通畅率为72%,二期通畅率为92%。覆膜支架组的一期通畅率显著高于裸支架组(P=0.007)。结论:覆膜支架腔内介入是治疗主髂动脉闭塞的有效方法,对于TASC II-C、D型病变较裸支架具有较高的一期通畅率。

Objective： To investigate the clinical effect of covered stent versus bare stent in the endovascular interventional treatment of aortoiliac occlusive disease. Methods： A total of 20 patients with aortoiliac occlusive disease who used covered stent and 25 patients who used bare stent in the endovascular interventional treatment in our hospital from January 2014 to December 2016 were enrolled. The two groups were compared in terms of primary patency rate, secondary patency rate, and clinical outcome. Results： All the 45 patients underwent the endovascular interventional treatment successfully. The follow-up time ranged from 5 to 39 months with a mean time of 14 ± 8 months. The covered stent group had a primary patency rate of 95% and a secondary patency rate of 100%, while the bare stent group had a primary patency rate of 72% and a secondary patency rate of 92%. The covered stent group had a significantly higher primary patency rate than the bare stent group （P = 0.007）. Conclusions： Endovascular interventional treatment with covered stent is an effective method for the treatment of aortoiliac occlusive disease, Compared with bare stent, it can achieve a higher primary patency rate in patients with TASC II-C or D lesions.
