摘要
目的:探讨皮层电图(ECoG)监测对切除癫痫病灶的应用价值及适应症。方法:对104例难治性癫痫患者使用盘状电极行ECoG监测下切除癫痫灶进行研究。结果:术前脑电图(EEG)检查86例异常(827%)。皮层电图102例异常(98%)。术后随访3个月至4年,有88例(846%)临床发作已控制,16例发作次数明显减少。复查常规EEG有痫样放电6例,慢波局限性改变5例,其余EEG均为正常。术前术后EEG阳性率相差显著。
Objective: To explore
the application value and the indication ofepileptic focus removal under surveillance of
electrocorticography(ECoG). Methods: One hundred and four patients with intractable epilepsy
were studied by means of removing epileptic focus under ECoG surveillance by disc-shaped
electrodes. Results:WT5BZAbnormal EEGs were observed in 86 patients(abnormality rate was
82.7%),and abnormal ECoG in 102 patients before operation.Following up of 3 months to four
years after operation the clinical attack was controlled completely in 88 patients(84.6%),the
times of clinical attack was decreased significantly in 16 patients.EEG recording showed
epileptiform discharges in 6 patients ,and focal slow waves in 5.The others were normal.There
was a significant difference between the positivity rates of pre-operative and post-operative
EEG. Conclusions: Removal of epileptic focus under ECoG surveillance might be of certain
clinical value.
