The localizing value of depth electroencephalography in 32 patients with refractory epilepsy

摘要: Clinical seizure manifestations, physical examination, radiological studies, neuropsychological tests, and scalp depth electroencephalographic (EEG) studies were done to localize foci in 32 patients, 23 of whom have undergone surgery with more than one year follow-up. Of 16 patients unlocalized EEGs, EEG detected a consistent focal onset 3. 15 localized revealed multiple 3 inaccurate localization the focus by 4. Therefore, was 10 31 patients. When this used determine surgical resection site, good excellent results obtained 12 13 additional origin, fair or poor all No other localizing criteria predicted success such accuracy. Furthermore, some criteria, including tests abnormalities, falsely at times. presently available appears be most accurate.
