Abstract
Objective To investigate the characteristics of endovascular intervention to treat complex ostial vertebral artery stenosis. Methods The 56 patients of complex ostial vertebral artery stenosis were summarized with endovascular treatment by vascular surgery at Xuanwu Hospital of Capital Medical University from 2013 Jun to 2015 Jun. The lesion features of the cases, the success rate of endovascular treatment, relief of postoperative symptoms, and the patency rate were analyzed. Results The complex of vertebral artery lesion was divided into three types: Type Ⅰwas the almost occlude lesion of vertebral artery, Type Ⅱ was the stenting of ostial vertebral artery need upper limb artery approach, and Type Ⅲ was the ostial vertebral artery lesion combined with the subclavian artery stenosis or occlusion. The success rate of endovascular treatment was 92.9%. Postoperative symptom improvement rate was 56.5%. The patency rate was 88.5% after 1 year. Conclusions Predilation could improve the stent success rate to the almost occlude lesion of vertebral artery. Upper limb artery approach could improve the stent success rate of vertebral artery. The vertebral artery should be protected during the procedure of the subclavian artery stenting. Key words: Vertebrobasilar insufficiency/SU; Angioplasty; Vascular surgical procedures; Stents
