颈动脉内膜剥脱术和支架成形术治疗颈动脉狭窄的临床研究

Carotid endarterectomy and carotid artery stenting for carotid artery stenosis

目的探讨颈动脉内膜剥脱术(CEA)和颈动脉支架成形术(CAS)治疗颈动脉狭窄的临床价值。方法选择颈动脉狭窄患者43例,分为CEA组20例和CAS组23例,分析比较CEA和CAS 2种治疗方法的疗效。结果 CEA组成功率为95%,术后随访2年,再狭窄率为10%;CAS组成功率为100%,术后随访2年,发生再狭窄率为13%,2组的手术成功率和术后再狭窄率比较,差异无统计学意义(P>0.05)。结论 CEA和CAS是治疗颈动脉狭窄的有效方法,两者在安全性和有效性方面相同。

Objective To study the clinical value of carotid endarterectomy and carotid artery stent- ing for carotid artery stenosis. Methods Forty-three patients with carotid artery stenosis were divided into carotid endarterectomy group（n= 20） and carotid artery stenting group（n= 23）. Curative effects of carotid endarterectomy and carotid artery stenting on carotid artery stenosis were analyzed and compared. Results The success rate of carotid endarterectomy was 95% for carotid artery stenosis. The patients were followed up for 2 years after operation during which the restenosis rate was 10%. The success rate of carotid artery stenting was 100% for carotid artery stenosis with a restenosis rate of 13% after operation. No significant difference was found in success rate of carotid endarterectomy and carotid artery stenting and in restenosis rate after carotid end- arterectomy and carotid artery stenting between the two group（P〉0.05）. Conclusion carotid endarterectomy and carotid artery stenting are the effective procedures for carotid artery stenosis with a similar safety and efficiency.
