目的探讨经颅多普勒超声(TCD)对椎基底动脉供血不足患者的诊断价值。方法对135例椎基底动脉供血不足患者进行检测分析,利用深圳德力凯公司NTS-9型TCD仪,探查双侧椎动脉及基底动脉,观察收缩期血流速度(Vp)、平均流速(Vm)、搏动指数(PI)的变化。结果在135例椎基底动脉供血不足患者,检测均以血流速度异常为主,占73.3%为主要讨论对象。结论 TCD检查具有准确、安全、无创伤、可重复性好等特点。对判断脑缺血程度、确定病变血管及病因的诊断均有重要价值,为理想的非创伤性诊断椎基底动脉供血不足的方法。
Objective To investigate the diagnostic value of transcranial Doppler ultrasound (TCD) in patients with vertebrobasilar insufficiency. Methods One hundred and thirty-five patients with vertebrobasilar insufficiency were detected and analyzed. The bilateral vertebral arteries and basilar arteries were probed with NTS-9 TCD instrument from Shenzhen Delikai Company. The systolic velocity (Vp), mean velocity (Vm ), Pulsatility index (PI) changes. Results In 135 patients with vertebrobasilar insufficiency, the abnormal blood flow velocity was the main measure, accounting for 73.3% as the main discussion object. Conclusion TCD examination with accurate, safe, non-invasive, good reproducibility and so on. To judge the degree of cerebral ischemia, to determine the pathological diagnosis of vascular disease and have important value, as the ideal non-invasive diagnosis of vertebrobasilar insufficiency method.
