定向斑块旋切治疗下肢股浅动脉硬化闭塞症

目的探讨定向斑块旋切治疗下肢股浅动脉硬化闭塞症的临床效果。方法选择下肢股浅动脉硬化闭塞症患者42例,随机分为观察组和对照组,各21例。观察组采用TurboHawk定向斑块旋切系统治疗,对照组采用球囊扩张及支架植入术治疗。收集数据,观察比较两组的治疗效果。结果观察组术后临床症状、踝臂指数改善情况与对照组差异无显著性(P>0.05)。观察组术后并发症发生率低于对照组,差异有统计学意义(P<0.05)。术后随访,观察组术后再狭窄率与对照组差异无显著性(P>0.05)。结论定向斑块旋切在治疗下肢股浅动脉硬化闭塞症中可以获得与球囊扩张、支架植入相似的通畅率,是一种安全、实用、有效的方法。

Directional atherectomy for the treatment of lower extremity superficial femoral arteriosclerosis obliterans

Aim To explore the clinical effect of directional atherectomy in the treatment of superficial femoral arteriosclerosis obliterans.Methods A total of 42 patients with superficial femoral arteriosclerosis obliterans of the lower extremities were selected and randomly divided into observation group and control group,with 21 cases in each group.The observation group was treated with TurboHawk directional atherectomy system,and the control group was treated with balloon expansion and stent implantation.Collect data,observe and compare the treatment effects of the two groups.Results The postoperative clinical symptoms and ankle brachial index(ABI)improvement of the observation group were not significantly different from those of the control group(P>0.05).The incidence of postoperative complications was lower in the observation group than that in the control group,and the difference was statistically significant(P<0.05).Postoperative follow-up showed that the restenosis rate of the observation group was not significantly different from that of the control group(P>0.05).Conclusions In the treatment of superficial femoral arteriosclerosis obliterans of lower extremities,directional atherectomy can achieve a patency rate similar to that of balloon dilatation and stent implantation.It is a safe,practical and effective method.
