Long-term VEEG monitoring and intracranial electrode EEG monitoring in the surgical treatment of temporal lobe epilepsy

Abstract

To explore the effect of long-term video-electroencephalography (VEEG) monitoring and intracranial electrode EEG monitoring in the surgical treatment of temporal lobe epilepsy. We compared the preoperative long-term VEEG and intraoperative intracranial electrode EEG in 44 patients undergoing surgical treatment of temporal lobe epilepsy. The 44 patients were followed up for 1 to 5 years. The clinical attack was controlled completely in 36 patients (81.8%), the time of clinical attack was decreased significantly in 6 patients (13.6%), 2 patients (4.5%) still had epileptic seizure, but the degree was relieved and the seizure time shortened. The nerve psychological function was improved to different extent in 40 patients (90.9%). Preoperative long-term VEEG and intraoperative intracranial electrode EEG are accurate in the localization of the focus, which is important in the surgical treatment of temporal lobe epilepsy.
