摘要
目的探讨视频脑电图及磁共振扫描对颞叶癫痫术前定位的准确性。方法回顾分析146例颞叶癫痫病例,术前均行长程视频脑电图(V/EEG)监测及磁共振扫描(MRI),发作时V/EEG所示的痫样放电部位与MRI检查所发现的病变同侧时,将此侧颞叶作为癫痫灶颞叶;MRI未见异常,则根据三次以上发作时V/EEG定侧。所有患者经术中皮层脑电图和深部脑电监测后,行前颞叶切除术。结果术中皮层脑电图及深部脑电监测均发现有痫样放电,与术前V/EEG监测吻合。术后102例(70%)癫痫发作完全消失,显著改善35例(24%),良好6例(4%),无改善3例(2%)。结论V/EEG结合MRI对颞叶癫痫术前能进行准确定位。
Objective To evaluate the accuracy of preoperative location of the epileptogenic zone in the temporal lobe epilepsy through vedio-- electroeneephalography combined with MRI scan. Methods 146 patients diagnosed temporal lobe epilepsy were analyzed retrospectively. V/EEG and MRI were applied for all cases preoperatively. When the epileptiform discharge recorded by V/EEG and positive finding by MRI originate from the same side, the temporal lobe of this side is regarded as epileptogenetic lesion. If no positive finding by MRI, at least triple V/EEGs arenended to indentify epileptogenic focus. The anterior temporal lobectomy was performed for all patients under the electrocorticogram and depth electroencephalography monitering during operation. Results Electrocorticogram and depth electroencephalography show epileptiform discharge in all cases consistent with preoperative V/EEG.. In the follow--up period, epileptic seizure disappeared in 102 cases(70%),improved significantly in 35 cases(24%), improved in 6 eases(4%) and not improved in 3 cases(2%). Conclusion Vedio--EEG combined with MRI can locate the epileptogenic zone accuratly before operation in the temporal lobe epilepsy.
