epileptogenic foci
3.Results With the cortical EEG monitoring, 16 patients underwent surgical resection of the epileptogenic foci identified by intraoperative EEG, 7 had multiple subpial transection and 12 received stereotactic radiosurgery for the epileptogenic foci localized by PET. In most of the cases, the epileptogenic foci were located around the lesions of encephalomalacia.
4.Study on Mechanism of Action of Vagus Nerve Stimulation and Epileptogenic Foci Irradiation by X-knife on Eplieptic Rats
5.Conclusions:ECoG might be of importment value in the localization of epileptogenic foci in the operation of patients with brain tumour and secondary epilepsy.
6.The epileptogenic foci detected by PET were consistent well with EcoG in 18cases(85.7%), consistent approximately in 2 cases and not consistent in 1 cases .
7.Results The epileptogenic foci localization coincidence 100% between the pre-operative localization and ECoG. The epileptiform discharges were disappeared in 9 patients,and significantly improved in 5 after operation.
8.Results: In 19 out of 23 patients 82.6%, the localization of epileptogenic foci by VEEG was consistent with that by ECoG , while in 16 out of 23 patients the localization by MRI was consistend with that by ECoG.
9.Result:Epileptogenic foci ean be correctly localized in 21 of cases by semiological study,in 9 of 27 cases by neuropsychological assessment,30 of 40 cases by routine surface/sphenoid electroencephalography(EEG),30 of 37 cases by electrocorticography(EcoG),29 of 35 cases by depth EEG(DEEG),12 of 25 cases by CT scan 32 of 40 cases by MRI.
10.Methods The retrospective analysis of the clinical data was made in 26 patients with secondary temporal lobe epilepsy, who were operated on from January 1994 to December 2002. The resection of the foci and epileptogenic cortex surrouding them, anterior temporal lobectomy, and multiple subpial transection were performed under the intraoperative surveillance of ECoG.
