Abstract:
Objective To assess the efficacy and feasibility of Wingspan stents for symptomatic atherosclerotic stenosis of the bas-ilar artery.Methods Clinical data of 40 patients with symptomatic atherosclerotic stenoses in the basilar artery were analyzed retro-spectively.The operative successful rate,the degree of stenosis,perioperative complications and the results of clinical and imaging follow-up were analyzed.Results The technical success rate was 95.35%.The rate of procedure-related complications during the perioperative period (30 days)was 20.0% (eight of 40 patients).There were two patients with no permanent neurological sequelae. Ipsilateral stroke or death occurred in six patients(1 5%).Thirty-six patients(92.3%)were available for a clinical follow up.The mean follow-up period was 36.3 months (range 12-75 months).Seventeen patients (47.2%)were available for follow-up imaging with DSA or CTA.The mean imaging follow-up period was 9.4 months (range 4-41 months).Symptomatic in-stent restenosis (ISR)was documented in two (1 1.76%)of these patients.Three ischemic events occurred during the follow-up period in 12 months.The adverse event rate was 8.33% at 1 year.Conclusion Wingspan stents for symptomatic atherosclerotic stenosis of the basilar artery was an effective and feasible technique,but we should carefully grasp the operation indications.
