Clinical research on treatment of symptomatic intracranial arterial stenosis with Wingspan stent
Abstract：Objective To investigate the safety,feasibility and long-term efficacy of the Wingspan stent in treatment of symptomatic intracranial arterial stenosis. Methods Treatment with Wing-span stent was attempted in 16 patients. The technical success rate,average stenosis before and af-ter treatment,major complications and clinical outcome were observed. Conventional cerebral an-giography was performed at 6 months after stenting. Results The average pretreatment stenosis was(80.6±12.1)%. After Wingspan stent placement, the average stenosis was(20.4±10.2)%.The technical success rate was 100%. The rate of ipsilateral stroke within 30 days and 6 months was 6.3% and 12. 5%, respectively. The symptoms were significantly improved in 68. 8% pa-tients. Five patients underwent conventional cerebral angiography reexamination,in-stent stenosis was detected in one patient with 80% restenosis. Conclusion Symptomatic intracranial artery ste-nosis can be treated with Wingspan stent with high rate of technical success,acceptable safety and clinic outcome.
