Video Summary

In this video transcript, a neurosurgeon from Shanghai Huashan Hospital presents their work on brain mapping and tumor resection. They emphasize the importance of maximally resecting tumors while minimizing neurological deficits. They discuss the use of pre-operative multimodal brain imaging, such as functional magnetic resonance imaging (fMRI), to help guide the extent of tumor resection while preserving critical brain areas. They also mention the limitations of fMRI, particularly for language mapping, and propose the use of diffusion tensor imaging (DTI) tractography to delineate functional white matter tracts. The surgeon discusses the use of intraoperative neurophysiological monitoring techniques, such as somatosensory evoked potentials and motor evoke potentials, to locate and preserve critical brain areas during surgery. They also describe their sedation awake approach for awake craniotomy, using continuous remifentanil infusion for anesthesia. The surgeon highlights the importance of awake craniotomy for language mapping and the use of their Brain Mapping Interactive Stimulation System (BRAINMISS) for intraoperative tasks and paradigm display. They demonstrate a video of a surgery using their system to perform cortical and subcortical mapping, followed by tumor resection. The surgeon emphasizes the benefits of various techniques in improving outcomes for patients undergoing surgery for eloquent area gliomas, and expresses gratitude to their team and the audience.
