腔内斑块切除在缺乏流出道的股腘动脉狭窄病变中的应用

目的:探讨腔内斑块切除治疗缺乏流出道的股腘动脉狭窄病变的疗效。方法:2014年7月—2015年6月笔者对所在单位21例以重度间歇跛行为主要症状、缺乏远端流出道的股腘动脉狭窄患者进行腔内斑块切除术,并进行随访。结果:与术前比较,患者术后3、6、12个月跛行距离均明显且逐渐增加(均P0.05);术后2d与3、6、12个月踝肱指数均明显增加(均P0.05);术后3个月无靶血管再狭窄,术后6个月发现靶血管再狭窄1例(1/21),术后12个月发现靶血管再狭窄2例(2/21),均为中度再狭窄。结论:腔内斑块切除术治疗缺乏流出道的股腘动脉狭窄病变具有较好的近期疗效。

Endovascular atherectomy for femoropopliteal artery stenosis with outflow obstruction

Objective: To investigate the efficacy of endovascular atherectomy in treatment of femoropopliteal artery stenosis with outflow obstruction. Methods: From July 2014 to June 2015, 21 patients who had femoropopliteal artery stenosis with distal outflow tract obstruction and severe intermittent claudication as the main symptom underwent endovascular atherectomy, and then they were followed up.Results: Compared with preoperative findings, the claudication distances of the patients at 3, 6 and 12 months after operation were all significantly increased with a rising trend (all P<0.05), and the ankle-brachial indexes of the patients on 2 d, and at 3, 6 and 12 months after operation were all significantly increased (all P<0.05). Restenosis of the target vessel did not occur in any of the patients at 3 months after operation, but occurred in one case (1/21) 6 months after operation and in 2 cases (2/21) at 12 months after operation, and all stenoses were of a moderate degree.Conclusion: Endovascular atherectomy offers a satisfactory short-term efficacy in treatment of femoropopliteal artery stenosis with outflow obstruction.
