OBJECT Intraoperative stimulation mapping of subcortical white matter tracts during the resection of gliomas has become a valuable surgical adjunct that is used to reduce morbidity associated with tumor removal. The purpose of this retrospective analysis was to assess the morbidity and functional outcome associated with this method, thus allowing the surgeon to predict the likelihood of causing a temporary or permanent motor deficit. METHODS In this study, the authors report their experience…

Subcortical stimulation mapping of descending motor pathways for perirolandic gliomas: assessment of morbidity and functional outcome in 702 cases.

Stimulation mapping allows surgeons to identify the descending motor pathways during resection of tumors in perirolandic regions and to attain an acceptable rate of morbidity in these high-risk cases.

Intraoperative mapping during repeat awake craniotomy reveals the functional plasticity of adult cortex.

The adult central nervous system reorganizes motor and language areas in patients with glioma through neural circuit reorganization or activation of latent functional pathways, suggesting that adult neural plasticity may help to preserve motor andlanguage function in the presence of evolving structural lesions.

Asleep triple motor mapping is safe and resulted in a low rate of deficits without compromising the extent of resection in patients with new or worsened postoperative motor deficits.

Intraoperative cortical mapping of visuospatial functions in parietal low-grade tumors: changing perspectives of neurophysiological mapping.

Evidence in the present study reveals that areas for visuospatial functions cannot be assessed with the same criteria used for language functions, since essential areas located in the tumor can be safely removed.

Multimodal Surgical Management of Cerebral Lesions in Motor-Eloquent Areas Combining Intraoperative 3D Ultrasound with Neurophysiological Mapping.

The integrated use of intraoperative neuromonitoring to identify motor areas and iUS to identify tumor-tissue interface could help increase the rate of radical resection respecting the eloquent areas.

Intraoperative monopolar mapping during 5-ALA-guided resections of glioblastomas adjacent to motor eloquent areas: evaluation of resection rates and neurological outcome.

Continuous dynamic mapping was found to be a very ergonomic technique that localizes the motor tissue early and reliably and can be achieved in glioblastomas in motor eloquent areas via a combination of 5-ALA for tumor identification and intraoperative mapping.

INTRAOPERATIVE SUBCORTICAL LANGUAGETRACT MAPPING GUIDES SURGICAL REMOVALOF GLIOMAS INVOLVING SPEECH AREAS

This study supports the routine use of subcortical stimulation for language tract identification as a reliable tool for guiding surgical removal of gliomas in or in close proximity to language areas or pathways.

Intraoperative DTI and brain mapping for surgery of neoplasm of the motor cortex and the corticospinal tract: our protocol and series in BrainSUITE

The preliminary series of patients treated for lesions involving the motor cortex and the corticospinal tract in BrainSuite, with intraoperative MRI, tractography and “neuronavigated” electrophysiological cortical and subcortical mapping highlights the good integration and the high compatibility between BrainSUITE with 1.5 T intraoperative magnetic field and neurophysiological monitoring.

The authors successfully used intraoperative electrical stimulations to perform subcortical language pathway mapping in order to avoid postoperative definitive deficit, and correlated these functional findings with the anatomical location of the eloquent bundles detected using postoperative MRI.

Somatotopy of the Supplementary Motor Area: Evidence from Correlation of the Extent of Surgical Resection with the Clinical Patterns of Deficit

Correlation between clinical patterns of deficit and the extent of SMA resection, guided by means of pre- and intraoperative functional methods, provides strong arguments in favor of somatotopy in this area.

Usefulness of Motor Functional MRI Correlated to Cortical Mapping in Rolandic Low-Grade Astrocytomas

When surgical resection of low grade astrocytoma in the motor areas is considered, FMRI used with intra-operative cortical mapping can help the surgeon to spare functional areas during tumour removal.

Awake craniotomy with brain mapping as the routine surgical approach to treating patients with supratentorial intraaxial tumors: a prospective trial of 200 cases.

Awake craniotomy is a practical and effective standard surgical approach to supratentorial intraaxial tumors with a low complication rate, and provides an excellent alternative to craniotom performed with the patient in the state of general anesthesia because it allows the opportunity for brain mapping and avoids general anesthesia.

Intra-operative direct electrical stimulations of the central nervous system constitute a reliable, precise and safe method, allowing the realization of a functional mapping useful for all operations of lesions located in eloquent areas.

Absence of movement disorders after surgical resection of glioma invading the right striatum.

It is shown that the nondominant striatum can be removed in cases of glioma invasion without inducing even transitory movement disorders, and this phenomenon could be explained by the combined resection of the two classes of striatal neurons, an associated pallidal and thalamocortical resection, or a compensated recruitment of parallel networks.
