To applied self-expanding stent deployment to symptomatic intracranial artery stenosis

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.
