摘要 目的 探讨椎基底动脉供血不足 (VBI)脑干功能与经颅多普勒 (TCD)的相关性。方法 对 6 8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% ,χ2 检验差异不显著 ;非VBI组脑干功能损害 8.3 % ,TCD异常率为 46 .6 % ,χ2 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 2 4/136 ,两者占 89.7% ;非VBI皆异常者为4/6 0 ,皆正常者为 32 /6 0 ,两者占 6 0 %。结论 根据临床表现 ,结合BR、BAEP及TCD检查结果可提高对VBI的诊断价值 。 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.
