动脉内膜剥脱和支架植入术治疗颈动脉狭窄的临床研究

The clinical study of carotid artery stenosis with endarterectomy and stenting

目的探讨动脉内膜剥脱和支架植入术治疗颈动脉狭窄的临床价值。方法30例颈动脉狭窄患者行颈动脉内膜剥脱术,35例行颈动脉成形和支架植入术,比较两种治疗方法的疗效差异。结果颈动脉内膜剥脱术的手术成功率为93.3%,术后3年再狭窄率为14.3%;支架植入术的手术成功率为100%,术后3年再狭窄率为18.7%,术后再狭窄率两者比较差异无统计学意义(χ2=0.214,P>0.05)。结论颈动脉内膜剥脱术和支架植入术是治疗颈动脉狭窄的有效方法,但支架植入术创伤小、并发症的发生率低,值得临床进一步推广。

Objective To investigate the clinical value of endarterectomy and stenting for carotid artery stenosis. Methods 30 patients and 35 patients with carotid artery stenosis received carotid endarterectomy and cerotid angioplasty and stenting, respectively, The therapeutic effect of two Kinds of methods was compared. Resuits The operative achievement ratio and the postoperative 3-year restenosis ratio of carotid endarterectomy were 93.3% and 14. 3%, respectively;The operative achievement ratio and the postoperative 3-year restenosis ratio of carotid stenting were 100.0% and 18.7%, respectively;The difference in postoperative restenosis ratio between two groups was insignificant（x^2 = 0. 214, P 〉 0. 05 ）. Conclusion Endarterectomy and stenting is the effective method in dealing with carotid artery stenosis, but carotid stenting is worthy to be spreaded clinically because of its lower trauma and complication ratio.
