椎基底动脉供血不足的脑电图与经颅多谱勒研究

Electroencephalogram and transcranial Doppler analysis of vertebrobasila ischemia

目的探讨脑电图(EEG)、转颈试验及经颅多谱勒(TCD)三相检查联合应用对椎基底动脉供血不足(VBI)的诊断价值。方法对35例VBI患者在眩晕发作间歇期作EEG时做转颈试验,同时做TCD检查。结果常规EEG、转颈试验的阳性率为8.6%、31.4%,二者相比差异有显著性,TCD阳性率为77.1%。结论转颈试验可提高EEG的阳性率。EEG与TCD检查从不同角度反映了VBI的病理生理基础,对VBI的诊断有参考意义。

Objective To explore the dignostic value of EEG, Neck rotation and TCD in patients with Vertebrobasilar insufficieney（VBI）. Methods EEG, neck rotation and TCD were performed in 35 patients with VBI in the interietall period. Results The abnormality rate of conventional EEG, neck rotation test were 8. 696 and 31. 496. A significant difference was noted between them. The abnormality rate of TCD was 77. 1%. Conclusion Neck rotation test might increase the positivity rate of EEG. EEG and TCD reflected the pathology and physiology basic of VBI from different point of view and might be of some significance for the diagnosis of VBI.
