Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | Eighty-eight patients suffering from temporal lobe epilepsy (TLE) underwent epilepsy-related
surgery monitored by preoperative long-term video EEG (VEEG) and intraoperative ECoG.
The patterns, location, and spatial distribution of epileptiform discharges recorded by VEEG
and ECoG were analyzed and compared. In 56 patients, frequent focal epileptiform discharges
were recorded by VEEG at one side of the temporal lobe and identified in the temporal lobe
and interior frontal gyrus by ECoG. Epileptiform discharges were recorded by VEEG at both
sides of the temporal lobe in 20 patients and by all recording electrodes at one side of the
temporal lobe in 12 patients. In these patients, epileptiform discharges were identified by
ECoG in the left sylvian gyrus of the temporal lobe and in the inferior and middle frontal
gyri. Spatial distributions of epileptiform discharges were adequately identified by ECoG in
52 (59%) patients, with a consistency of > 80% in 24 (27%) patients, and with a consistency
of 60-80% in 12 (14%) patients, compared with that estimated by VEEG. Patients remained
seizure-free in 72 (81.8%) cases; their state was improved significantly in 12 (13.6%) cases
and remained unimproved in 4 (4.5%) cases. Our data suggest that ECoG possesses certain
advantages over VEEG in accurate localization of the epileptogenic foci and, thus, is important
for surgical treatment of TLE. |
