视频脑电图监测对癫痫的临床应用价值

目的:探讨视频脑电图(Video-EEG)对癫痫的临床应用价值。方法:对975例发作性疾病患者进行连续90 min~24 h监测,其中包括清醒、睡眠期,分析临床发作和异常放电的关系。异常放电出现的时相,癫痫分型与异常放电的关系,临床发作前脑电图的改变,以及临床发作间期和发作期异常脑电图的不同表现。结果:975例监测到临床发作568例,期中同时伴异常放电者为443例,975例检出异常放电741例,确诊的443例中403例明确了发作类型,其中125例修正了发作类型,55例更换了药物治疗,16例适时停用了药物,76例难治性癫痫监测到发作前脑电图的异常改变,确定了致痫灶的位置,进行了手术治疗。结论:视频脑电图监测可提高痫样放电的检出率,有助于癫痫的诊断及分型,指导临床用药及术前致痫灶的定位。

Clinical Application Value of Video-EEG Monitoring in Epilepsy

Objective To explore the clinical application value of Video-EEG monitoring in epilepsy.Methods Video-EEG monitoring under state of awaking and sleeping were performed continuously in 975 patients with paroxysmal events.We analysed the relation between seizures and abnormal discharge,the phase when abnormal discharge appeared,and relation between classification of epilepsy and abnormal discharge.We also observed EEG changes before seizures and different EEG findings in both ictal and interictal period.Results The characteristic events were captured in 568 of the 975 patients and out of the 568 patients,443 had clinical events accompanying epileptiform discharge.Seizure types were defined in 403 of 443 patients with epilepsy seizure,and 125 seizure types were amended.The antiepileptic drugs were changed in 55 cases.With drawled in 16 cases,76 refractory epilepsy patients whose EEG were abnormal change before seizure were performed operations.Conclusion VEEG can record much more epileptiform discharge.It is an effective method in both diagnosis and classification of epilepsy.To guide medical therapy and preoperative localization of epilepeogenic zone.
