Abstract：Objective To explore the role of 128-channel long-term video electroencephalograph ( VEEG) in locating epileptogenic focus of drug-resistant epilepsy , selecting operational way and valuing efficiency of operation .Methods A total of 22 patients with drug-resistant epilepsy were analyzed with 128-channel long-term video EEG ( EEG9200K), and we compared the results with outcomes of magnetic resonance (MR) and PET.Results ①The results of scalp EEG, MR and PET fit epileptogenic foci in 9 cases well, they all underwent operation and were followed up for 3-36 months.Nine ca-ses were found that they had no seizures in three months after operation , and no seizures were found in follow-up.②Epi-leptic foci of 13 cases could not be located by scalp EEG , MR and PET, but conld be located by intracranial EEG (IEEG) with 128-channel long-term video EEG and 13 cases underwent operation .They were followed up for 3-32 months.Thirteen cases were found that they had no seizures in 3-6 months after operation .After operation for 6-36 months, 11 cases were found no seizures , and 2 cases suffered from seizures in 6 months after operation and seizure was stopped by the increased dose of AEDs .Conclusions Patients should be actively operated with fitting phase I assessment of epileptogenic foci by scalp EEG, MR and PET.Patients who couldn't be located on phase I assessment should undergo IEEG by using 128-chan-nel long-term video EEG and be operated after function orientation .IEEG can be used as gold standard for locating epilep-togenic focus and selecting the operation mode .
