摘　　要：目的：探讨视频脑电图（V-EEG）检查在婴儿痉挛诊断中的作用。方法：对2003年5月至2009年5月新诊断未经治疗的83例婴儿痉挛患儿进行V-EEG监测，分析监测录像中婴儿痉挛发作的临床表现和发作期以及发作间期的脑电图（EEG）特点。结果：83例共监测到78例112次临床发作，主要有3种类型典型发作，发作期EEG共7种形式。发作期EEG：患儿几乎都表现为高波幅慢波或单个高波幅尖慢波或棘慢波，随后出现弥漫性低电压，其它放电形式则少见。发作间期EEG以典型的高度节律失调（高度失律）和变异型的高度失律为主。结论：V-EEG能观察到婴儿痉挛的独特轴性发作形式，有时还能监测到合并其它形式发作，又能对发作期和发作间期EEG进行完整记录。发作间期EEG表现为高度失律失调及其变异型是大多数婴儿痉挛患儿的特征性EEG类型。V-EEG监测可为诊断和鉴别诊断婴儿痉挛症提供重要依据。Objective： To explore the the functions of video-EEG for the diagnosis of infantile spasms . Methods：The characteristics of clinical and video-EEG were analysed in interictal phase and ictal phase in 83 new patients with infantile spasms from May 2003 to May 2005. Results： 112 episodes of spasms were recorded,which were mainly three subtypes. There were 7 EEG patterns in ictal phase with the common patterns being single high voltage slow waves followed by electrodecremental pattern,sharp and slow wave complex（or only spike-slow wave） followed by electrodecremental pattern, the other pat- terns（rare）. EEGs were abnormal in interictal phases and typical hypsarrhythmia and its variants were predominant. Conclusion：Axial spasms in infants spasms can manifest multiple types and are accompanied by other seizure types. EEGs in ictal and interictal phases show various patterns. Hypsarrhythmia and its variants are interictal EEG characteristic patterns in most patients. Video-EEG can provide strong evi- dences for the diagnosis and differential diagnosis of infantile spasms.
