目的：探讨Wingspan支架对症状性颅内动脉狭窄的治疗情况，评价其安全性及可行性。方法：应用Wing span支架治疗症状性颅内动脉狭窄患者36例，观察围手术期情况及术后随访情况，观察支架置入的手术成功率、狭窄率的改变、围手术期并发症、临床随访及影像学随访结果。结果：本组36例手术成功率为100％，围手术期（术后30d）并发症发生率为5．6％（2例）。28例患者接受了影像学（DSA或CTA）随访，在12个月随访期间，2例患者出现无症状性支架内再狭窄，1例患者出现症状性支架内再狭窄，再狭窄率为10．7％，1年不良事件发生率为8．3％。结论：对药物难治性症状性颅内动脉狭窄患者行Wing span支架成形术是有效、可行的。

Objective:To retrospectively analyze the treatment of symptomatic intracranial arterial steno‐sis with Wingspan stent and to evaluate the feasibility and safety. Methods :36 patients with symptomatic intracrani‐al arterial stenosis were treated by Wingspan stent. The operative successful rate, the degree of stenosis, periopera‐tive complications and the results of clinical and imaging follow‐up were observed. Results:The technical success rate was 100%. The rate of procedure‐related complications during the perioperative period (30 days) was 5. 6% (two of 36 patients). Twenty‐eight patients were available for follow‐up imaging with DSA or CTA. During 12 months, One patient was symptomatic in‐stent restenosis (ISR), two patient was asymptomatic in‐stent restenosis (ISR). The restenosis rate was 10. 7%. The adverse event rate was 8. 3% at 1 year. Conclusion:For refractory symptomatic in‐tracranial arterial stenosis, Wingspan stents is an effective and feasible technique. But in the long term, we need fur‐ther follow up.
