CiteScore measures average citations received per document grafo. The purpose of our paper has been to study the benefits of an original protocol developed for the microsurgical treatment of tumors located in eloquent motor areas where the navigation and electrical stimulation of baj subcortical pathways have been implemented.

The majority of spinal cord gliomas reporting metastasis were anaplastic astrocytomas or glioblastomas multiforme and relatively few were low-grade gliomas. El volumen tumoral medio era de There was a great correlation between anatomic and functional data, both cortically and subcortically.

Astrocitoma pilocítico

Pueden producirse en el cerebro y la columna. Extent of surgical resection is independently associated with survival in patients with hemispheric infiltrating low-grade gliomas.

Leptomeningeal dissemination through cerebrospinal fluid is unusual and occurs predominantly in medulloblastomas, ependymoblastomas, central neuroblastomas, ependymomas, germ cell tumors and high-grade gliomas.

Three-dimensional mapping at microscopic resolution, topography and intersubject variability. The location of all cortical and subcortical stimulated points with positive motor response was stored in the navigator and correlated with the cortical or subcortical motor functional structures defined preoperatively. The integration of preoperative and intraoperative anatomic and functional studies allows a astrocotoma functional resection of the brain tumors located in eloquent areas, compared to the tumoral resection based on anatomic imaging studies.
