椎—基底动脉供血不足是椎—基底动脉系统发生的缺血性血液循环障碍、累及椎动脉或(及)基底动脉。近年来,经颅多普勒超声(TCD)的应用,为椎—基底动脉供血不足的定性、定位诊断提供了一项无创伤且简便、安全的技术手段。本文通过对150例该病患者的TCD检查,初步探讨椎—基底动脉供血不全的多普勒超声改变及其临床意义。报告如下。1 材料和方法1.1 临床资料:本组150例均来自我院神经内科病房及门诊。年龄32～80岁,平均59岁;男96例,女 Vertebrobasilar insufficiency is a disorder of the ischemic blood circulation of the vertebrobasilar artery system involving the vertebral artery or (and) the basilar artery. In recent years, the application of transcranial Doppler ultrasound (TCD) provides a noninvasive, simple and safe technique for the qualitative and localization diagnosis of vertebrobasilar insufficiency. In this paper, TCD examination of 150 cases of patients with this disease, preliminary study of vertebrobasilar insufficiency by Doppler ultrasound changes and its clinical significance. The report is as follows. 1 Materials and Methods 1.1 Clinical data: 150 cases in this group are from our hospital neurology wards and clinics. Age 32 to 80 years, mean 59 years; 96 males and females
