Efficacy analysis of stent angioplasty on symptomatic stenoses of vertebral arteries origins / 中国基层医药

ABSTRACT

Objective To evaluate the safety and efficiency of endovascular stenting on symptomatic stenosis of vertebral artery origin .Methods 62 patients with symptomatic stenosis of vertebral artery origin received vertebral stenting.Before and after operation ,vascular stenosis rate and clinical symptoms were observed ,and follow-up on all cases.Results The stents was successfully performed in 62 patients.The symptomatic stenosis and clinical symptoms were significantly improved.The stenosis rate decreased from (77.4 ±15.3)%to (12.2 ±6.5)%.The postoperative follow-up lasted for 6-42months.5 cases developed restenosis .Conclusion Endovascular stenting for symptomatic stenosis of vertebral artery origin is safe and effective ,but the long-term curative effect of this technique should be further observed .
