经腔内血管成形术治疗动脉粥样硬化病变的头臂血管，目前正在选定的病例中进行。应用球囊扩张术治疗椎动脉狭窄17例，基底动脉狭窄1例。临床表现包括椎基底动脉功能不全、反复短暂性脑缺血发作（tia）和多发性中风。我们对16例因动脉粥样硬化导致的优势椎动脉明显狭窄（大于70%）的患者进行了成功的腔内血管成形术。一名基底动脉狭窄合并串联动脉粥样硬化病变的患者也采用血管成形术治疗。间隔3至12个月复查血管造影显示血管成形术部位持续通畅。1例基底动脉成形术患者治疗后发生脑干梗死，1例双侧椎动脉成形术后发生TIA，均出现并发症。另外两名患者有残余椎体狭窄，但手术后仍无症状。所有其他扩张成功的患者在随访6个月至2年（平均15个月）时无症状。这些初步研究表明，椎动脉血管成形术可能对治疗高级别动脉粥样硬化病变和改善后循环的血液流动有效。基底动脉的血管成形术在技术上更困难，而且风险更高，因为有许多贯穿脑干的分支。
Transluminal angioplasty of brachiocephalic vessels for atherosclerotic lesions is now being performed in selected cases. We have thus far treated 17 cases of vertebral artery stenosis and one case of basilar artery stenosis by intravascular balloon dilatation techniques. Clinical presenting symptoms included vertebral basilar insufficiency, repeated transient ischemic attacks (TIAs), and multiple strokes. We performed successful transluminal angioplasty in 16 patients with marked narrowing (greater than 70%) of the dominant vertebral artery from atherosclerosis. One patient with basilar artery stenosis with tandem atherosclerotic lesions was also treated by angioplasty techniques. Repeat angiography at 3- to 12-month intervals has revealed continued patency at the angioplasty site. Complications occurred in our one patient with basilar artery angioplasty, who suffered a brainstem infarction after treatment, and in one patient who had a TIA after bilateral vertebral artery angioplasty. Two other patients had residual vertebral stenosis but remained asymptomatic after the procedure. All other patients who had successful dilatation were asymptomatic at 6 months to 2 years (mean, 15 months) of follow-up. These initial studies indicate that vertebral artery angioplasty may be effective for treating high-grade atherosclerotic lesions and for improving blood flow to the posterior circulation. Angioplasty of the basilar artery is technically more difficult and has a higher degree of risk because of the many perforating branches supplying the brainstem.
