Primera experiencia en Cuba con la implantación crónica de electrodos subdurales en un paciente con epilepsia

Zusammenfassung

INTRODUCTION: The implementation of a protocol in Cuba for epilepsy presurgical evaluation was developed 10 years ago at the CIREN (International Center of Neurological Restoration). This protocol was implemented at the Institute of Neurology and Neurosurgery since May 2010. None of these institutions had performed an epilepsy surgery with chronic subdural electrode implantation. The purpose of this communication is to present for the first time the performance of this procedure in Cuba by the team of epilepsy surgery at the Institute of Neurology and Neurosurgery in La Habana (INN).CASE REPORT: 32–year old male patient with refractory extratemporal epilepsy caused by dysplasia of the fusiform gyrus. The patient had perictal schizophreniform psychosis. The presurgical evaluation carried out at the INN considered a concordant case in lateralization but not in localization. The symptomatogenic zone compromised the posterior third of the superior temporal gyrus, right angular gyrus, and subsequently both temporal lobes. The lesion area was located in the right fusiform gyrus. The functional deficit zone was both limbic cortices. The interictal epileptiform activity showed right parieto–temporal involvement and the ictal onset zone evaluated with video–EEG was found in the electrode P4. To accurately define the area to be resected a chronic subdural electrode implantation was performed.CONCLUSIONS: The first chronic subdural electrode implantation was performed without complications in Cuba.
