We report a case of awake resection of temporal low-grade glioma infiltrating the optic radiation (OR). The OR was localized by direct electrical stimulation (DES) and the tumor was delineated by navigated intraoperative 3D ultrasound. Ultrasound artifacts were eliminated by 3D-ultrasound data acquisition with a miniature probe inserted into the resection cavity. A total of 97 % resection was achieved, and small tumor portion involving OR was intentionally left in place. Functional result was partial quadrantanopia instead of more profound visual deficit, which would follow gross-total resection. To our knowledge, DES of OR was reported once; the aforementioned method of ultrasound artifact elimination has not been reported before.

Awake Craniotomy for Eloquent Brain Arteriovenous Malformations: A Systematic Review and Individual Patient Data Meta-Analysis.
World Neurosurg
December 2024
Department of Neurosurgery, University of São Paulo, São Paulo, Brazil.
Background: Arteriovenous Malformations (AVMs) pose a risk of neurologic deterioration, particularly when located in eloquent areas. While awake surgery is well-established for treating low-grade gliomas near eloquent areas, its efficacy for AVMs is less conclusively reported.
Methods: This study conducted a systematic review and individual patient data (IPD) meta-analysis following Cochrane Collaboration and PRISMA guidelines.

Objective: To provide an explanation for the intraoperative onset of severe naming deficits in the course of awake resection of left insular glioma.
Methods: We retrospectively reviewed a series of 14 patients operated on in awake conditions for a left insular IDH-mutated glioma. Preoperative MRI included high-resolution diffusion sequences, to which constrained spherical deconvolution pipeline was applied, to obtain a whole brain tractogram.
Level I and II deficits-A clinical survey on international practice of awake craniotomy and definitions of postoperative "major" and "minor" deficits.

Department of Neurological Surgery, University of California, San Francisco, California, USA.
Background: Awake craniotomy (AC) is a technique that balances maximum resection and minimal postoperative deficits in patients with intracranial tumors. To aid in the comparability of functional outcomes after awake surgery, this study investigated its international practice and aimed to define categories of postoperative deficits.
Methods: A survey was distributed via neurosurgical networks in Europe (European Association of Neurosurgical Societies, EANS), the Netherlands (Nederlandse Vereniging voor Neurochirurgie, NVVN), Belgium (Belgian Society of Neurosurgery, BSN), and the United States (Congress of Neurological Surgeons, CNS) between April 2022 and April 2023.

The authors report a rare case of a 58-year-old female with mild right-sided hemifacial spasms and eyelid myokymia and a concomitant high-grade glial mass. This report outlines the clinical presentation, diagnostic approach, and management of right hemifacial spasms and eyelid myokymia. The patient had a 5-month history of gradually worsening right hemifacial spams accompanied by mild right lower eyelid twitching.
