视频脑电图监测对癫癎的诊断价值

目的探讨视频脑电图(VEEG)在小儿癫诊断中的应用价值。方法对癫组166例、可疑癫组患儿49例,应用美国PI VEEG400-C型视频脑电图仪进行3~4 h的动态监测,包括至少1个清醒-睡眠周期,完成各种诱发试验。结果癫组VEEG性放电124例(74.5%),监测到临床发作26例,其中癫发作20例,非癫发作6例;可疑癫组VEEG性放电13例(26.5%),监测到临床发作16例,其中癫发作3例,非癫发作13例。137例性放电的患儿中99例(72.3%)确定了发作类型,43例(30.6%)明确了癫综合征的诊断。结论视频脑电图监测在鉴别癫性发作性质、确定癫发作类型、评价脑电-临床关系方面提供了准确可靠的依据。

Diagnostic Value of Video-Electroencephalogram in Children with Epilepsy

Objective To explore the practicle value of video-electroencephalogram(VEEG)in diagnosis of epilepsy in childhood.Methods One hundred and sixty-six children diagnosed as epilepsy group and 49 children suspected to be epilepsy(suspicious epilepsy group) were monitored with VEEG instrument(PI VEEG 400-C) for 3-4 hours under the state of awaking and sleeping and with all kinds of evoked tests.Results Among 166 cases of epilepsy group,124(74.5%) patients were confirmed as epilepsy,clinical seizures were observed in 26 cases of suspicious epilepsy group,6(23.1%) cases were identified as non-epileptic attacks;Among 49 cases,13((26.5%)) patients were confired as epilepsy,clinical seizures were observed in 16 cases,13(81.3%) cases were identified as non-epileptic attacks.Seizure types were difined in 99 of 137(72.3%) children with epileptic discharges,and epileptic syndromes were defined in 43((30.6%)) of them.Conclusion VEEG can provide accurate and reliable information in diagnosis and classification of epilepsy.
