Endovascular treatment of vertebral artery stenosis (VAS) is a safe and effective technique for treating symptoms caused by posterior circulation ischemia with high technical and clinical success rates, low complication rates and durable long-term results. Variable restenosis rates have been reported in the literature with small improvements demonstrated using drug eluting stents. Although there is insufficient evidence from randomized trials to demonstrate superiority of endovascular compared to optimal medical therapy for the treatment of this disease, patients who fail medical therapy should be considered for endovascular stenting for symptomatic VAS. This manuscript will examine and review the endovascular treatment options for extracranial VAS.
椎动脉狭窄（VAS）的血管内治疗是一种安全有效的技术，用于治疗后循环缺血引起的症状，具有较高的技术成功率和临床成功率、较低的并发症发生率以及持久的长期效果。文献报道了不同的再狭窄率，药物洗脱支架显示出较小的改善。尽管随机试验的证据不足，无法证明血管内治疗相对于最佳药物治疗在治疗该疾病方面具有优越性，但对于药物治疗无效的有症状VAS患者，应考虑进行血管内支架置入术。本文将研究和综述颅外VAS的血管内治疗选择。
