Invasive monitoring with intracranial electrodes continues to play a critical role in the presurgical evaluation of patients with medically intractable epilepsy. Intracranial monitoring helps in localizing the epileptogenic zone and can be used to delineate eloquent cortical areas adjacent to this zone. In this review we analyzed surgical successes and failures of invasive video-electroencephalography (EEG) monitoring. ⋯ Intraparenchymal hematomas are even less frequent and are typically associated with the placement of depth electrodes. In 47-98% of cases, invasive video-EEG monitoring results into resective surgery. Invasive video-EEG monitoring is a reasonably safe and effective method to help delineate the epileptogenic zone and its relation to eloquent cortex.
