婴儿痉挛患儿临床与视频脑电图分析

Clinical and video EEG analyses of infantile spasms

目的探讨监测录像中婴儿痉挛发作的临床表现和发作期脑电图特征。方法对50例首诊婴儿痉挛患儿的视频脑电图及临床资料进行回顾性分析。结果本组患儿产时产后的脑损伤是导致婴儿痉挛的主要原因之一；发作形式为屈曲型28例，伸展型10例，混合型12例；发作期脑电图表现为高一极高波幅慢波、尖-慢、棘-慢复合波，发作间歇期脑电图表现以典型的高度节律为主。结论大多数婴儿痉挛患儿脑电图呈高度失律型的特征，但不一定都出现高度失律。

Objective To explore the clinical manifestations and ictal EEG fea- tures of infantile spasms monitoring video recording. Methods Video EEG and clinical data of 50 infants with first-diagnosis of infantile spasms were retrospec- Intra- and post-partum brain injury were one of the main causes resulting in in-fantile spasms; 28 infants were flexing type sei- zure, 10 extended, and 12 mixed; ictal EEG mani-festations were high sharp-slow and spike-slow complex wave, intermittent EEG manifestations were char- acterized by typical high rhythm. Conclusion EEGs of most infantile spasms show hypsarrhythmia fea- tures, hut hypsarrhythmia doesn＇t emerge necessarily.
