支架置入术治疗有症状大脑中动脉狭窄的初步观察

目的:研究支架置入术治疗有症状大脑中动脉狭窄的可行性、有效性和安全性.方法:2005年8月-2006年12月,对12例大脑中动脉狭窄的患者行血管内支架置入术.其中男性9例,女性3例,平均年龄(69±5.3)岁,范围56～81岁.平均狭窄程度(84.2±3.7)%,范围50%～99%.所有患者都用球囊扩张支架成功地进行了治疗,且无任何严重的并发症.结果:术后血管残余狭窄率≤20%,随访6～18个月期间无患者再发脑缺血症状.结论:血管内支架置入术是治疗有症状大脑中动脉狭窄的一种安全而有效的方法,近期效果显著.

Stenting for Symptomatic Middle Cerebral Artery Stenosis: A Preliminary Observation

Objective:To investigate the feasibility,effectiveness and safety in the treatment of symptomatic middle cerebral artery stenosis with stenting.Methods:Twelve patients with middle cerebral artery stenosis were treated with stenting from August 2005 to December 2006.Among these patients,9 were male and 3 were female.The meam(SD)age was 69(5.3)years(range 56 to 81 years).The mean(SD)stenosis degree was 84.2%(3.7)(range 50% to 99%).All patients were successfully treated with balloon-expanded stents.and there was not any severe complications.Results:The rate of residual stenosis after the procedures was≤20%.No cerebral ischemic symptoms recurred in the patients over a 6-to 18-month follow-up period.Conclusions:Endovascular stenting is a safe and effective approach in the treatment of symptomatic middle cerebral artery stenosis,and its short-term effect is significant.
