OBJECT Mapping and monitoring are believed to provide an early warning sign to determine when to stop tumor removal to avoid mechanical damage to the corticospinal tract (CST). The objective of this study was to systematically compare subcortical monopolar stimulation thresholds (1-20 mA) with direct cortical stimulation (DCS)-motor evoked potential (MEP) monitoring signal abnormalities and to correlate both with new postoperative motor deficits. The authors sought to define a mapping threshold…

The authors postulate a mapping MT of 1 mA or less where irreversible DCS-MEP changes and motor deficits regularly occur and recommend stopping tumor resection at an MT of 2 mA at the latest.

Intraoperative subcortical motor evoked potential stimulation: how close is the corticospinal tract?

Subcortical MEP mapping is an excellent intraoperative method to determine the distance to the CST during resection of motor-eloquent lesions and is highly capable of further reducing the risk of a new neurological deficit.

Transcranial versus direct electrical stimulation for intraoperative motor-evoked potential monitoring: Prognostic value comparison in asleep brain tumor surgery

Data support the use of mapping and combined monitoring via TES and DCS, and the sole TES monitoring is reliable in most procedures but not in parietal tumors or those requiring lateral positioning.

Continuous dynamic mapping of the corticospinal tract during surgery of motor eloquent brain tumors: evaluation of a new method.

Continuous dynamic mapping was found to be a feasible and ergonomic technique for localizing the exact site of the CST and distance to the motor fibers and may increase the safety of motor eloquent tumor surgery.

Mapping and Monitoring of the Corticospinal Tract by Direct Brainstem Stimulation

The relationship between stimulation intensity and DS-to-T in brainstem surgery could help surgeon's better estimate the safe edge intraoperatively and further supports the paradigm for continuous CST monitoring and mapping through direct brainstem stimulation.

Continuous Dynamic Mapping to Identify the Corticospinal Tract in Motor Eloquent Brain Tumors: An Update.

Continuous dynamic mapping was found to be a feasible and ergonomic technique for localizing the exact site of the CST and distance to the motor fibers and may improve the safety of motor eloquent tumor surgery.

Low-threshold monopolar motor mapping for resection of lesions in motor eloquent areas in children and adolescents.

High-frequency train-of-five with a minimal threshold of 1-3 mA is a feasible and safe procedure for resection in pediatric patients with lesions located within the precentral gyrus and close to the CST, and may be regarded as a functional navigational tool.

The Minimal Subcortical Electronic Threshold Predicts the Motor Deficit and Survivals in Non-Awake Surgery for Gliomas Involving the Motor Pathway

This study showed strong cause–effect relation between MSCMT and postoperative motor deficit and prognoses and power model has the best fitness for paired monopolar and bipolar high-frequency thresholds.

The preoperative nTMS-based risk assessment can help to interpret ambiguous IOM phenomena (such as irreversible MEP amplitude decrease ≤50%) and adjustment of SCS stimulation intensity.



Low-Threshold Monopolar Motor Mapping for Resection of Primary Motor Cortex Tumors

Preliminary data demonstrate that a monopolar HF-TOF threshold > 3 mA was not associated with a significant new motor deficit, indicating close proximity of motor neurons.

Significance of intraoperative motor function monitoring using transcranial electrical motor evoked potentials (MEP) in patients with spinal and cranial lesions near the motor pathways

Intraoperative motor evoked potential monitoring in patients with spinal and cranial lesions is thought to be a valuable tool for prevention of postoperative motor deficits and its diagnostic value in a spinal and a cranial patient group was investigated.

Predictive value and safety of intraoperative neurophysiological monitoring with motor evoked potentials in glioma surgery.

Continuous MEP monitoring provides reliable monitoring of the motor system, influences the course of operation in some cases, and has to be regarded as the standard for IOM of theMotor system.

The investigators found that diffusion tensor imaging-based tractography is a reliable way to map the white matter connections in the entire brain in clinical and basic neuroscience applications and could contribute to elucidating the neural networks of the human brain and shed light on higher brain functions.

Intraoperative mapping and monitoring of the corticospinal tracts with neurophysiological assessment and 3-dimensional ultrasonography-based navigation. Clinical article.

Combining elaborate neurophysiological assessment, tractography-based neuronavigation, and updated IOUS images provided accurate localization of the corticospinal tracts and enabled the safe resection of tumors approximating these tracts and provided an intraoperative technique to better preserve motor function.

The monopolar probe can be safely implemented in an i MR imaging environment both for navigation and stimulation purposes during the resection of intrinsic brain tumors and can be used in the iMR imaging environment as a surgical adjunct to minimize adverse neurological outcomes.

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

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.

Intraoperative preservation of corticospinal function in the brainstem

MEP monitoring—as opposed to SEPs—is a valid indicator of corticospinal function in brainstem-related surgery, independent from the type of lesion operated on, and may help to prevent permanent new paresis.

Intraoperative Motor Evoked Potential Alteration in Intracranial Tumor Surgery and Its Relation to Signal Alteration in Postoperative Magnetic Resonance Imaging

MEP loss bears a higher risk than MEP deterioration for postoperative motor deficit resulting from subcortical postoperative MR changes in the corticospinal tract, and even MEP deterioration should be considered a warning sign if surgery close to the motor cortex is performed.
