摘　　要：目的分析椎基底动脉缺血性眩晕老年患者颅脑多普勒超声(TCD)检查的血流动力学指标以及异常情况。方法选取2014—2016年茌平县人民医院收治的90例椎基底动脉缺血性眩晕患者90例为观察组,选取同期健康体检的老年人为对照组,对比2组TCD检测指标及检查结果异常率。结果 90例椎基底动脉缺血性眩晕患者中TCD检查存在异常的患者73例(81.11%),其中60例为椎基底动脉血流异常(82.19%)。观察组大脑前动脉(ACA)、大脑中动脉(MCA)、大脑后动脉(PCA)以及基底动脉(BA)与椎动脉(VA)的Vm均明显低于对照组(P<0.05),ACA、VA、BA的PI指数明显高于对照组(P<0.05)。结论椎基底动脉缺血性眩晕老年患者TCD检查可见颅内血流指标改变明显,椎基底动脉改变较为明显。Objective To analyze the hemodynamic parameters and abnormalities of craniocerebral Doppler ultrasonography (TCD) in elderly patients with vertebrobasilar ischemic vertigo. Methods 90 cases of vertebral basilar ischemic vertigo treated in Chiping County People's Hospital from 2014 to 2016 were selected as observation group.The elderly with healthy physical examination were selected as the control group.The TCD detection index and abnormal test results were compared.rate. Results Of the 90 patients with vertebrobasilar ischemic vertigo,73 (81.11%) had abnormal TCD,of which 60 had abnormal vertebrobasilar blood flow (82.19%).The Vm of the anterior cerebral artery (ACA),middle cerebral artery (MCA),posterior cerebral artery (PCA),basilar artery (BA) and vertebral artery (VA) in the observation group were significantly lower than those in the control group ( P <0.05),ACA,The PI index of VA and BA was significantly higher than that of the control group ( P <0.05). Conclusion TCD examination of vertebrobasilar ischemic vertigo in elderly patients showed significant changes in intracranial blood flow indicators,and vertebral basilar artery changes were more obvious.
