50年代中期 Hutchinson 和 Yates 指出:椎动脉起始部的动脉硬化可引起脑干和枕叶的局部缺血,但病人常忽略椎-基底动脉供血不全(VBI)的症状,并把头晕、眩晕、晕厥和共济失调等症状归因于年龄因素。双侧椎动脉疾病引起的 VBI,进行椎动脉重建可使功能明显改善。许多学者认为单侧椎动脉狭窄在临床上是不重要的。作者报道两名单侧椎动脉狭窄致残性 VBI 病人,用 IMP 标记脑血流行 SPECT 检测,结果显示 Hutchinson and Yates in the mid-1950s pointed out that atherosclerosis in the initial part of the vertebral artery can cause ischemia in the brainstem and occipital lobe, but patients often overlook the symptoms of vertebrobasilar insufficiency (VBI) and dizziness, dizziness, Symptoms such as syncope and ataxia are attributed to age. VBI caused by bilateral vertebral artery disease, vertebral artery reconstruction can significantly improve the function. Many scholars believe that unilateral vertebral artery stenosis is not clinically important. The authors report two patients with unilateral vertebral artery stenosis VBI disabled, IMP marked cerebral blood flow SPECT test results show
