Intracranial electroencephalographic and evoked-potential recording from intravascular guide wires.
We describe a technique for recording electroencephalographic and evoked-potential information directly from the cerebral hemispheres and brain stem, via an endovascular approach. Recordings were performed with polytef-insulated guide wires in the course of interventional angiographies in 23 patients. All registrations were compared with simultaneous recordings from extracranial electrodes. This preliminary study raises the possibility that this technique may help to explore the electric activity of deep cerebral structures otherwise accessible only by stereotactic puncture or electrode insertion.
