目的探讨小儿典型失神发作(TAS)、额叶癫发作(FLES)及婴儿痉挛(IS)的临床表现、发作间期及发作时脑电图的特点。方法对经电视录像脑电图(Video-EEG)监测后诊断为TAS、FLES及IS患儿的临床和脑电图资料进行回顾性分析。结果①TAS32例发作87次,其中复杂性失神28例。发作时脑电图为双侧对称同步的3Hz棘慢波。发作间期睡眠时棘慢波发放不规则。②FLES18例43次,15例具有2种或2种以上发作形式。14例发作间期睡眠时有额区棘(慢)/尖(慢)波,16例发作时额区出现癫性放电。③IS17例22次,发作间期清醒时均为高峰节律紊乱,睡眠期各导棘慢波趋向同步化。发作时为全导弥漫性单个高幅慢波及波幅低平等。结论TAS、FLES及IS的临床表现、发作时和发作间脑电图各有特点,在诊断时要综合分析。Video-EEG有助于上述发作频繁的小儿癫发作的准确诊断。
Objective To investigate the clinical manifestations, interictal seizures and characteristics of EEG at onset in children with typical absence seizures (TAS), frontal epilepsy (FLES) and infantile spasms (IS). Methods The clinical and EEG data of TAS, FLES and IS patients monitored by Video-EEG were retrospectively analyzed. Results ①TAS 32 cases were attacked 87 times, including 28 cases of absence of complexity. EEG attack at the onset of symmetrical bilateral 3Hz spikes and waves. Intermittent spikes and waves during sleep irregularities. ② FLES 18 cases 43 times, 15 cases with two or more than two seizures. There were 14 spikes (slow) / sharp (slow) waves in the 14 seizures, and epileptiform discharge in the frontal area in 16 seizures. ③IS17 cases 22 times, when the interictal awakening are peak rhythm disorders, sleep during the various spines and slow waves tend to synchronize. All-cause diffuse single high amplitude slow wave and low volatility equal. Conclusion TAS, FLES and IS clinical manifestations, seizures and episodes of EEG have their own characteristics, at the time of diagnosis to be a comprehensive analysis. Video-EEG helps to accurately diagnose the above episodes of infantile seizures.
