摘　　要：目的:探讨颈动脉狭窄支架置入术预防脑梗死的临床意义。方法:对27例颈动脉狭窄患者施行支架置入术,分析颈动脉支架置入术的有效性和安全性。动脉狭窄率50%～70%7例,70%～80%19例,80%～95%1例;狭窄长度1.0～2.0cm14例,2.1～3.0cm12例,3.1～3.5cm1例。结果:27例在脑保护装置下颈动脉支架置入术均成功实施,残余狭窄均在10%以下。4例球囊扩张时出现一过性意识障碍,4例出现暂时性心率减慢,3例出现血压下降。临床随访6个月以上,无死亡及神经系统并发症发生。结论:颈动脉狭窄支架置入术是预防脑梗死的有效手段,不仅使狭窄段血流速度恢复,而且能明显改善远端脑组织低灌注现象,减少脑卒中的发生。Objective：To evaluate the clinical value of carotid artery stenting （CAS） for protecting the ischemic cerebrovascular disease.Methods：27 patients who were diagnosed with symptomatic carotid artery stenosis by DSA were performed CAS so as to analyse the validity and safety of CAS for treating the patients with symptomatic carotid artery stenosis. The degree of stenosis was 50% - 70% in 7 patients,70% - 80% in 19 patients,80% - 95% in 1 patients, and the length of stenesis was 1.0 - 2.0 cm in 14 patients, 2.1 - 3.0 cm in 12 patients, 3.1 - 3.5 cm in 1 patients. Results： The CAS of 27 cases were all successful under the brain protective device. The degree of stenosis was decreased under 10%, there were 4 cases with swoon when balloon dilatated, and there were 4 cases with heart rate showdown, as well as three cases with blood pressure declined. More than six months of dinical follow-up, no one died or nervous system complications occurred. Conclusion： Carotid artery stenosis stenting is an effective mean to prevent of cerebral embolism, not only to narrow the speed of blood flow resumed, and can significantly improve remote brain tissue hypoperfusion phenomenon, reduce the incidence of stroke.
