目的：探讨椎基底动脉供血不足（ＶＢＩ）、腔隙性脑梗死（腔梗）的临床及ＣＤＳ改变的异同。方法：对患者进行眼底、颈椎Ｘ线片、脑血管彩色多谱勒超声（ＣＤＳ）扫描。结果：ＶＢＩ组、腔梗组，眼底动脉硬化Ⅰ度、Ⅱ度之间有显著性差异，有无颈椎骨质增生之间也有显著性差异。ＣＤＳ检查两组均有明显的脑动脉硬化，ＶＢＩ组椎动脉（ＶＡ）、基底动脉（ＢＡ）血流速度减慢，腔梗组大脑前动脉（ＡＣＡ）、大脑中动脉（ＭＣＡ）血流速度异常增快。结论：颈椎病与ＶＢＩ密切相关；脑动脉硬化确是缺血性脑血管的病理基础；ＣＤＳ检查有助于ＶＢＩ和腔梗的诊断。
Objective: To investigate the clinical and CDS changes of vertebrobasilar insufficiency (VBI) and lacunar infarction (parietal infarcts). Methods: The fundus, cervical X - ray and cerebrovascular color Doppler echocardiography (CDS) were performed on the patients. Results: The VBI group, the lumen group and the fundus atherosclerosis had significant difference between Ⅰ degree and Ⅱ degree, and there was also significant difference between the two groups. CDS showed obvious cerebral arteriosclerosis in both groups, the blood flow velocity of vertebral artery (VA) and basilar artery (BA) of VBI group was slowed down, and the blood flow velocity of cerebral anterior cerebral artery (ACA) and middle cerebral artery (MCA) Abnormally faster. Conclusions: Cervical spondylosis is closely related to VBI; cerebral arteriosclerosis is indeed the pathological basis of ischemic cerebrovascular disease; CDS examination is helpful for the diagnosis of VBI and luminal infarction.
