Article Synopsis
  • Awake microsurgery is a way to treat brain aneurysms while the patient is awake, allowing doctors to monitor their brain activity during the surgery.
  • In a study analyzing 75 patients, the procedure had very few complications, with no permanent issues reported, and it was successful in repairing aneurysms in all cases.
  • More research is needed to confirm that this method is safer and better than current surgical options, but it shows promise for helping patients recover more easily.

Introduction: The combined use of intraoperative MRI and awake surgery is a tailored microsurgical resection to respect functional neural networks (mainly the language and motor ones). Intraoperative MRI has been classically considered to increase the extent of resection for gliomas, thereby reducing neurological deficits. Herein, we evaluated the combined technique of awake microsurgical resection and intraoperative MRI for primary brain tumours (gliomas, metastasis) and epilepsy (cortical dysplasia, non-lesional, cavernomas).

Background: Intraoperative neurophysiological monitoring (IONM) is utilized for both the localization of critical structures and for real time detection and prevention of intraoperative neurological injury. Use of IONM to monitor the hypoglossal nerve is performed during neurosurgical, otolaryngological, and vascular procedures to improve surgical outcomes. There is a paucity of literature describing potential complications of IONM of the hypoglossal nerve, especially with respect to airway compromise.

Article Synopsis
  • - The text discusses a case of a 27-year-old male patient who underwent awake surgery for a cavernous malformation in a sensitive brain area that caused hemorrhage and epilepsy, using advanced imaging techniques.
  • - The surgery involved a combination of preoperative diffusion tensor imaging, neuronavigation, and intraoperative MRI to successfully remove the malformation, despite patient movement during the procedure.
  • - Post-surgery, the patient experienced a single seizure but showed no significant complications, and follow-up imaging confirmed complete removal of the malformation with normal cognitive function reported in neuropsychological tests.

Objective: Arteriovenous malformations (AVMs) located in eloquent brain regions are historically associated with a poor prognosis. Awake craniotomy (AC) with the adjunct of brain mapping has the potential of identifying non-eloquent gyri to maximize resection, thereby theoretically decreasing the risk of neurologic deficits. With limited evidence regarding the efficacy of AC in treatment of eloquent AVMs, this review aims to investigate its surgical outcomes.
