Abstract
The state of the art in contemporary glioma surgery is the irremediable fight between anatomic, supramarginal and functional tumor resections. All our efforts are focused on increasing the ‘progression-free survival’ but not at any cost, as the neurological function preservation is nowadays considered as a must. Low grade glioma patients are now considered as long survivors, who should be able to continue with their normal lives after surgical treatments for a long time. Therefore, achieving supramarginal resections, by predicting, detecting and respecting the eloquent areas of the human brain represents the gold-standard on glioma surgery. In this sense, preserving the visual function is of extreme importance, especially in those patients whose daily routine requires a normal visual field. Visual pathways represent a complex anatomy not easily recognizable into the surgical field due to its depth and different directions followed into the periventricular areas. We present our protocol and results after implementing a novel method to detect the optic radiations based on preoperative MRI images and an original intraoperative campimetry implemented to the subcortical stimulation device. The use of this method has allowed us to maximize our resections, as well as to decide the safest surgical trajectory in certain cases.
