Stereo-Encephalography Versus Subdural Electrodes for Seizure Localization

摘要

In today's practice, epileptologists and neurosurgeons have several options for seizure localization with intracranial electrodes during phase II evaluations. Traditionally, centers in North America have used subdural electrode grids (SDE or SDG) for intracranial seizure localization. However, improvements in technology led to the popularization of stereo-encephalography (SEEG) using depth electrodes. Epilepsy surgery centers highest in volume now offer both SDE and SEEG for seizure localization. This article provides a general guide for considering SEEG versus SDE for intracranial seizure localization based on our experience with both. Several paradigmatic cases are used to illustrate the advantages and disadvantages of the different approaches.
