Clinical impact of transcranial unilateral motor evoked potentials monitoring in cerebral aneurysm endovascular treatment.
A modified transcranial motor evoked potential montage avoided movement-related interruptions during endovascular coil embolization of cerebral aneurysms.
Clinical impact of transcranial unilateral motor evoked potentials monitoring in cerebral aneurysm endovascular treatment.
This study aimed to address these limitations by evaluating the feasibility of an optimized transcranial electrical stimulation motor evoked potential (TES-motor evoked potential) protocol designed to minimize body movement while preserving monitoring reliability.
We performed a retrospective review of 62 aneurysms treated with endovascular coil embolization for cerebral aneurysms under total intravenous anesthesia (total intravenous anesthesia).
MEPs were successfully obtained in all cases, with no procedures interrupted by patient movement.
Our modified montage facilitated stable monitoring, eliminating digital subtraction angiography (digital subtraction angiography) misregistration and the need for repeated imaging.
Intraoperative motor evoked potential amplitude reductions occurred in two patients, both linked to ischemic events and prompting timely intervention.
Our transcranial electrical stimulation MEP monitoring method is feasible and safe in neuroendovascular procedures.
By reducing procedure-disrupting movement while maintaining ischemia detection, the protocol improves workflow safety and holds meaningful potential to enhance patient outcomes.
Given its retrospective design, the study is subject to inherent limitations, and prospective studies are warranted to validate these findings and further refine stimulation protocols.
