颈动脉狭窄支架置入术的临床研究

目的分析总结颈动脉颅外段狭窄患者支架置入术后的疗效及其并发症，探讨其安全性与可行性。方法对41例因颈内动脉颅外段狭窄〉70％的患者进行了支架置入术。其中22例狭窄严重者使用了脑保护装置。结果所有患者均经DSA血管造影证实有颈动脉狭窄，支架置入术后残余狭窄率均低于50％，手术成功率100％。41例患者中有7例出现低血压、心动过缓，2例出现高灌注综合征、2例出现可逆性小卒中（非脑保护装置支架植入术中）。术后随诊2～24个月（平均随诊12±2．6个月），临床疗效满意。1例发生非支架侧脑梗死。结论血管支架置入术为颈动脉狭窄患者提供了一种新的、有前途的治疗手段。

Clinical study of stent placement for carotid stenosis

Objective To study the safety and efficacy of stent placement for carotid stenosis.Methods Carotid artery stenting(CAS)was performed in 41patients with carotid stenosis. Further cerebral protection devices were performed in 22 out of 41 patients with severe stenosis.Results Digital subtraction angiography(DSA)confirmed that all patients suffered from carotid stenosis. The residual stenosis was lowered to less than 50% after the surgery The successful rate of stent implantation was100%without any serious complication.Durng operation 7 patienes had hypotension and bradycardia and 2 patients had hyperperfusion syndrome,2 patienes without cerebral protection devices had reversible Cerebral ischemia. Over a mean 12-month follow-up, We found that one case of cerebralinfarction found out in non-stent side. Conclusion CAS provided a new, promising treatment for patients with carotid stenosis.
