Overview
Preliminary evaluation of depth electrode recording and novel algorithms to determine Cortical Spreading Depolarization's (CSD) following traumatic brain injury (TBI) requiring neurosurgical intervention.
Description
During the standard of care External Ventricular Drain (EVD) placement, a depth electrode with minimal modification to the standard surgical procedure will be placed. This will allow electrocorticogram (ECoG) recordings. An ECoG will be reviewed by a study Neurosurgeon to understand the association between cortical spreading depression and pathological findings on imaging. The recordings help create a novel algorithm in order to detect CSD's. This may ultimately provide significant benefit to society through the diagnosis and treatment of secondary injury associated with traumatic brain injury.
