RESUMEN
Objective:To summarize experience of vertebral artery stenting in nine cases with vertebral artery stenosis for providing reference for clinical treatment .Methods :Success rate of operation ,vertebral artery stenotic degree before and after operation were evaluated in nine cases undergoing vertebral artery stenting .Results:A total of nine stents were implanted in nine cases and the success rate of operation was 100% ,after stents were implanted blood flow was unobstructed ,stent expansion was good and intracranial blood supply was good .Compared with before op‐eration ,stenosis rate significantly reduced after operation [(84.0 ± 5.7)% vs .(10.0 ± 2.0)% ] (P<0.01) .No vas‐cular restenosis occurred within three‐year follow -up .Conclusion:Vertebral artery angioplasty and stenting is a new emerging ,minimally invasive ,effective and highly safe therapeutic method for vertebral artery stenosis ,the therapeutic effect is sure and application prospect is broad .
