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 investigate the accuracy of video EEG and MRI in preoperative localization of temporal lobe epilepsy. Methods A total of 146 patients with temporal lobe epilepsy were retrospectively analyzed. Long-term video electroencephalography (EEG) and magnetic resonance imaging (MRI) were performed preoperatively. The epileptiform discharge sites indicated by V / EEG at the time of onset and the MRI findings Of the lesion ipsilateral, this temporal lobe as temporal lobe epileptic foci; MRI no abnormalities, then based on more than three episodes of V / EEG side. All patients underwent anterior temporal lobe resection after intraoperative cortical EEG and deep EEG monitoring. Results Intraoperative cortical EEG and deep EEG monitoring showed that epileptiform discharges were consistent with preoperative V / EEG monitoring. Seizures completely disappeared in 102 (70%) postoperative patients, with a significant improvement in 35 (24%), good in 6 (4%) and no improvement in 3 (2%). Conclusion V / EEG combined with MRI preoperative temporal lobe epilepsy can accurately locate.
