摘要：目的与方法：采用经颅多普勒超声对260例椎—基底动脉短暂性脑缺血发作(TIA)患者进行颅内动脉检测。结果：发现226例血管流速异常(占86.9%)。主要表现为椎—基底动脉系统血流速度异常(53.1%)，部分患者颈内及椎—基底动脉系统流速均有异常(28.3%)；少数患者单纯表现颈内动脉系统流速异常(18.6%)。结论：表明经颅多普勒超声(TCD)为临床研究椎—基底动脉TIA患者的血液动力学改变及临床诊断、观察病情、指导用药及早期预防提供了较为理想的非外伤性检测手段。

    Abstract: Objective and Method： 260 cases TIA in verte bralis-basilar artery were detected encephalic artery by TCD. Result: The result slaved that blood velocity of flow were abnormity in 226 cases (86.9%). The main symptoms of blood velocity of flow in verte-bralis-basilar artery is 53.1%, and only part of them is 28.3% only a few of them with simply abnormity in encephalic artery blood velocity of flow. Conclusion: The TCD detection is an ideal way to the symptoms drug use and early prevention and blood dynamic in TIA of verte bralis-basilar artery. ......
