68例椎基底动脉供血不足瞬目反射和脑干听觉诱发电位与经颅多普勒的相关性

目的 探讨椎基动脉供血不足（ＶＢＩ）脑干功能与经颅多普勒（ＴＣＤ）的相关性。方法 对６８例临床诊断ＶＢＩ的患者及３０例非ＶＢＩ患者进行ＢＲ、ＢＡＥＰ和ＴＣＤ检测。结果 ＶＢＩ组脑干功能损害８４．６％，ＴＣＤ异常率为８３．１％，χ＾２检验差异不显著；非ＶＢＩ组脑干功能损害８．３％，ＴＣＤ异率为４６．６％，χ＾２检验差异显著。ＶＢＩ组脑干功能损害及ＴＣＤ异常者为９８／１３６，皆正常者为２４／１３６，两

Correlation of blink reflex,brainstem auditory evoked potentials and transcranial doppler in 68 cases of vertebrobasilar ischemia

Objective To study the correlation between brainstem function and transcrainal doppler (TCD) examination on the vertebrobasilar ischemia (VBI). Methods Sixty eight cases with VBI and 30 cases without it but with vertigo were studied with blink reflex (BR), brainstem auditory evoked potentials (BAEP) and TCD on the right and left sides. Results The incidence of brainstem function injuries was 84.6%, and abnormal TCD 83.1% in VBI group, there being no significant difference in Chi square test; While in non VBI group brainstem function injuries were 8.3%, abnormal TCD 46.6% . Both brainstem function injuries and TCD abnormal were 98/136 of patients with VBI, but normal in 24 sides. While in non VBI it was 5/60 in abnormal and 32/60 in normal. Conclusion The study indicates that clinical signs combined with BR, BAEP and TCD may give a more reliable diagnosis of VBI. While TCD alone is not a relable basis for the diagnosis of VBI.
