摘　　要：目的:探讨64导长程视频脑电图(VEEG)对症状性癫痫的定位价值。方法:回顾性分析2015年6月至2019年12月于昆明医科大学第一附属医院行病灶及癫痫灶切除的患者50例,所有患者术前均行常规脑电图(REEG)及64导长程VEEG检查,术中皮层脑电图(ECoG)监测验证64导长程VEEG定位的准确性。结果:50例患者64导长程VEEG监测发作间期及发作期痫样放电检出率为90%(45/50例),REEG为46%(23/50例),差异具有统计学意义(x^2=14.13,P<0.01)。64导长程VEEG与ECoG的定位吻合率为90%。结论:64导长程VEEG对症状性癫痫患者致痫区的检出率和定位率高,有助于癫痫灶的术前无创定位。Objective:To explore the value of 64-lead long-term video-EEG(VEEG)in the localization of symptomatic epilepsy.Methods:Fifty patients who underwent focal and epileptogenic foci resection in the First Affiliated Hospital of Kunming Medical University from June 2015 to December 2019 were analyzed retrospectively.The routine EEG(REEG)and 64-lead long-term VEEG were performed in all patients before operation.The accuracy of long-term VEEG localization was verified by intraoperative electrocorticography(ECoG)monitoring.Results:The detection rate of epileptiform discharge was 90%(45/50 cases)by 64-lead long-term VEEG,46%(23/50 cases)by REEG,with statistical differences(X2=14.13,P<0.01).The location coincidence rate of 64-lead long-range VEEG and ECoG was 90%.Conclusion:The detection rate and localization rate of 64 lead long-term VEEG in epileptogenic area of patients with symptomatic epilepsy is high,which is helpful for the noninvasive localization of epileptic focus before the operation.
