Motor Evoked Potential Monitoring during Cerebral Aneurysm Surgery: Technical Aspects and Comparison of Transcranial and Direct Cortical Stimulation

Abstract

The cogent comprehensive combination of transcranial and direct cortical electrical stimulation allows for the continuous mMEP monitoring of the cerebral vascular territory of interest in 99% of the patients with cerebral aneurysms. Unwarranted effects of electrode placement and stimulation are rare and without clinical consequences.
