目的:下肢动脉硬化闭塞症患者临床治疗中经皮腔血管成形术与内支架联合治疗取得的效果观察.方法:选取医院下肢动脉净化闭塞症患者66例(2019年1月-2020年1月),以数字1:1分组方式,33例采用单纯经皮腔血管成形术方法(对照组),另外33例在对照组治疗基础上辅以内支架治疗方法(观察组),对两组患者治疗效果观察.结果:治疗后观察组胫后动脉踝肱指数与足背动脉踝肱指数观以及踝肱指数ABI相比对照组组间对比均有显著差异(P＜0.05).结论:经皮腔血管成形术应用于下肢动脉硬化闭塞症患者治疗中,辅以血管内支架治疗“,”Objective: To observe the efect of percutaneous transluminal angioplasty combined with internal stent in patients with arteriosclerosis obliter-ans of lower extremity. Methods :66 patients with lower extremity arterial purification occlusion ( January 2019 - January 2020), Packed in numbers 1:1, 33 cases were treated with simple percutaneous angioplasty ( control group), The other 33 cases were treated with internal stent ( obser-vation group) The therapeutic efect of the two groups was observed. Results: There were significant diferences between the tibial posterior artery ankle brachial index ABI the dorsal foot artery ankle brachial index and ankle brachial index ( P ＜ 0. 05 ). Conclusion: Transdermal angioplasty is used in the treatment of lower extremity arteriosclerosis obliterans, With an endovascular stent, The effect is idea.
