Resumen:
Purpose : Stereo- electroencephalography (SEEG) is aprocedure performed for patients with intractable epilepsyin order to anatomically define the epileptogenic zone (EZ)and the possible related functional cortical areas. Electricalstimulation (ES) was developed to identify with precisioncortical structures essential to language and motorfunction, and to trigger seizures. The aim of this study is toanalyze electrical stimulation (ES) findings in our patientpopulation.Method : We analyzed 30 patients with drug resistant epilepsyfrom our Video- EEG Unit, who underwent a SEEG as part ofa surgical plan. Cognitive tasks performed during ES were:hand tapping, naming, automatic speech (counting), readingand verbal fluency.Results : From the 30 patients, we trigger theirs usualseizures in 25 (83.33%), 159 seizures: 25 (15.5%) weretrigger with hippocampus stimulation, 15 (9.4%) amygdala,30 (18.8%) other temporal areas, 50 (31.4%) frontal areas,15 (9.4%) parieto- occipital areas, and 24 seizures (15%)were obtained with the stimulation of two continues areas.In 14 (46.6%) patients we stimulate eloquent brain regions:8 (57%) language, 7 (50%) patients were evaluated themotor area, 2 (14.2%)sensitive areas, 4 (28.4%) visual and5 (28.4%)auditory sensations. We define EZ in all of thepatients, 8 (26.6%) mesial temporal lobe epilepsy, 2 (6.6%)other temporal areas, 13 (43.3%) frontal lobe epilepsy,5 (21.7%) parieto- occipital epilepsy, 2 (6.6%) insularepilepsy.Conclusion : ES is a procedure that allowed us the accuratelocation of the EZ, the temporal space dynamics of theepiletogenic network and the functional mapping, to plancortical resection without overlap and to improve postsurgicalprognosis.
