长程视频同步脑电监测在儿童癫痫诊断和分类中的价值

【目的】 评价长程视频脑电图监测(video-EEG monitoring,video-EEG)在儿童癫痫的临床诊断和分型中的应用价值。 【方法】 对98例临床拟诊为癫痫的患儿进行连续12~18 h的包括清醒及睡眠的长程video-EEG监测。 【结果】 98例患儿中,发现痫样放电比例为91.8%(90/98),44例癫痫样放电与临床发作同步出现(44.9%),长程Video EEG监测前根据临床表现诊断全面性发作占53.1%(52/98),局限性发作占43.9%(43/98)。不能分类的发作有3例,占3.0%(3/98);长程video-EEG监测后全面性发作共32例,占32.7%,局限性发作共有 60 例,占61.2%,不能分类的发作2例,占2%。监测前后发作类型一致的有58例,不一致的有40例。 【结论】 长程视频同步脑电图监测对于儿童癫痫的临床诊断和分类有重要的价值。

Diagnostic value of video-electroencephalogram in classifying seizure types of children with epileptic seizure

【Objective】 To explore the value of video-electroencephalogram(long-term video-VEEG)in diagnosis of epilepsy in childhood.【Method】 98 children diagnosed or suspected to be epilepsy were monitored with video-EEG instrument for 12~18 hours under the state of awaking and sleeping.【Results】 The positive rate of epileptiform discharges in patients with epilepsy was 91.8%(90/98),44 seizures(44.9%,44/98) were recorded.52 of them were diagnosed as generalized seizures(53.1%,52/98),43 of them were partial seizures(43.9%,43/98) and 3 of them were non-classified(3.0%,3/98) seizures according to clinical symptomatology before long-term video-EEG monitoring.However,32 of them were diagnosed as generalized seizures(32.7%,32/98),31 of them were partial seizures(61.2%,60/98) and 4 of them were non-classified(2.0%,2/98) seizures according to ictal or interictal VEEG monitoring.58 of their epileptic seizure types were consistent and 40 were inconsistent after VEEG monitoring.【Conclusion】 Clinical episodes with epileptiform discharge of long-term video-EEG monitoring have significant diagnostic value in classifying seizure types of children with epileptic seizure.
