目的 探讨应用颅内自膨式专用支架治疗症状性颅内动脉狭窄的有效性、安全性.方法 61例症状性颅内动脉狭窄患者(直径狭窄率>70%)接受了65枚颅内专用支架治疗,其中Wingspan支架40枚,Neuroform支架25枚.结果 技术成功率达100%,病变动脉的狭窄程度纠正50%～90%,平均为72%,无血管撕裂、急性动脉闭塞、远端血管栓塞事件等并发症出现,术后3-24个月复查,2例出现完全闭塞,但无明显临床症状.结论 自膨式颅内专用支架的应用,有效提高了手术的安全性和成功率,但长期疗效需要进一步观察.%Objective To study the safety and efficacy of serf-expanding stent for symptomatic intracranial artery stenosis. Method 61 patients with symptomatic intracranial artery stenosis (rate of diameter stenosis > 70%) accepted 65 serf-expanding stents deployment, including 40 wingspan stents and 25 neuroform stents. Results The technically successful rate was 100%. The average artery stcnosis was retrieved by 72% after stent deployment. There was no arterial dissection, acute occlusion of the target artery or symptomatic distal emboli. Within the follow-up period (3-24 months), 2 patients endured asymptomatical artery full occlusion. Conclusions The application of self-expanding stent could elevate the operative safety and effectiveness. However,further study is needed to evaluate the long-term therapeutic effect.
