Approximately 20% to 40% of patients who have cerebral vascular disease have a vertebral artery-origin stenosis. Atherosclerotic lesions of vertebral arety origin are a potential cause of posterior circulation ischemia, which can be disabling or deadly. Endovascular treatment of vertebral artery-origin and innominate/subclavian artery stenosis has changed in the last 15 years. Surgery usually is successful technically; however, it is also associated with high rates of procedural and periprocedural complications. New techniques and technologies that can be used in the treatment of such lesions are being developed. In this article, the authors discuss the indications, technical aspects, and long-term results of angioplasty and stenting of these vessels.
约20%至40%的脑血管疾病患者存在椎动脉起始部狭窄。椎动脉起始部的动脉粥样硬化病变是后循环缺血的潜在原因，可导致残疾或死亡。在过去15年中，椎动脉起始部及无名动脉/锁骨下动脉狭窄的血管内治疗发生了变化。手术在技术上通常是成功的；然而，它也与较高的手术及围手术期并发症发生率相关。可用于治疗此类病变的新技术和方法正在不断发展。在本文中，作者讨论了这些血管血管成形术和支架置入术的适应证、技术要点及长期疗效。
