Endovascular treatment of the ostial and proximal portions of the vertebral artery is a safe and effective technique for alleviating symptoms and improving cerebral blood flow to the posterior circulation. Vertebral artery angioplasty can be performed with high technical and clinical success rates, low complication rates, and durable long-term results. Although restenosis rates range from 0% to 48%, the durability of vertebral artery angioplasty is evidenced by low restenosis rates in multiple large series reported in the literature using multiple treatment options, including balloon angioplasty alone, bare metal stents, and drug-coated stents.
椎动脉开口处和近端的血管内治疗是一种安全有效的技术，可缓解症状并改善后循环的脑血流量。椎动脉血管成形术的技术成功率和临床成功率高，并发症发生率低，长期效果持久。尽管再狭窄率在0%至48%之间，但在文献报道的多个大型系列研究中，使用包括单纯球囊血管成形术、裸金属支架和药物涂层支架在内的多种治疗方案，椎动脉血管成形术的低再狭窄率证明了其耐久性。
