经颅多普勒超声联合脑电图对老年烟雾病的诊断价值

Transcranial Doppler and Electroencephalogram diagnostic value to gerontal patients with moyamoya disease

目的探讨经颅多普勒超声(TCD)联合脑电图(EEG)对老年烟雾病的诊断价值。方法对18例确诊为烟雾病患者的TCD及脑电图检查资料进行回顾性分析。结果 TCD示18例患者颅底大动脉均有不同程度的狭窄及闭塞性病变;脑电图示18例患者过度换气(HV)结束数分钟后均出现再次慢波增强现象。结论 TCD对颅底大动脉病变的高敏感性和高特异性,结合患者脑电图再次慢波增强这种特征性的改变,对老年烟雾病的诊断具有独特价值,可作为老年烟雾病的常规筛查手段。

Objective To analysis and verify the specificity for Transcranial Doppler(TCD)and Electroencephalogram(EEG)diagnostic value to gerontal patients with moyamoya disease.Methods We reviewed and analysised the TCD and EEG of eighteen moyamoya case.Results The different degrees stricture of Basilar artery of the eighteen case diagnosed by TCD could be detected by EEG,which shows Slow wave enhancement again after the end of hyperventilation(HV)a few minutes.Conclusion The susceptibility and specificity of TCD to Basilar artery and Slow wave enhancement again of EEG are of great diagnostic value to gerontal patients with moyamoya disease,TCD and EEG may serve as routine screening test to diagnose such a disease.
