Depth Electrode Monitoring after Traumatic Brain Injury

Official title: Depth Electrode Cortical Reverberation Monitoring After Traumatic Brain Injury

Run by Hennepin Healthcare Research Institute · NCT07842458 · Data updated 2026-11-12

This study tests adding a depth electrode with continuous brain monitoring during external ventricular drain placement in adults with traumatic brain injury to see if cortical reverberation signals can be tracked safely.

Is this trial a fit for you?

Likely a good fit

Adults 18 years or older who are recommended for EVD placement after TBI and can provide English consent.

Probably not a fit

Patients without reliable access to the electrode or with exclusion criteria (e.g., infection, coagulopathy, non-English speakers) may not benefit.

What this trial studies

This is a small feasibility study in adults with TBI who need an external ventricular drain. A multi-contact depth electrode will be placed adjacent to the EVD catheter during standard care, with ongoing cortical stimulation and recording to detect patterns related to cortical reverberation and seizures. Recordings are reviewed daily by a neurosurgeon or epileptologist to identify electrographic seizure activity and other signals of interest. The goal is to determine whether this monitoring approach can be implemented safely and provide meaningful information about brain activity after injury.

Why it matters

Potential benefit: If feasible, this approach could provide real-time brain activity data that might help guide treatment to reduce secondary brain injury.

How similar studies have gone: Prior observational work suggests that monitoring brain activity after TBI can reveal patterns linked to worse outcomes; this study tests a novel, feasibility approach.
