Implementation of ORBEYE-Exoscope in the Operative Treatment of Spinal Dural Arteriovenous Fistula.

Spinal dural arteriovenous fistulas (sDAVFs) are rather uncommon lesions of the spine. In sDAVFs, which represent the most frequent form of vascular malformations of the spine, operative treatment remains the most common treatment modality. In operative surgery, visualization and pathology detection have a key impact on the results of the neurosurgical treatment of an sDAVF.

Department of Neurosurgery, Radboud University Medical Center, Nijmegen, the Netherlands.
Research Question: The goal of this study was to assess the diagnostic accuracy of spinal time-resolved contrast-enhanced MR angiography (4D-MRA) for the detection and localization of spinal dural arteriovenous fistulas (SDAVF) in our institution.
Material And Methods: Single center retrospective cohort study of patients with the clinical suspicion of a SDAVF. Patients were included who had undergone spinal 4D-MRA in the period January 2010-February 2021.
Brain mapping during resection of high-grade brain arteriovenous malformation.

Eloquent brain creates a challenge when resecting brain arteriovenous malformations (bAVMs). Here the authors present their technique of using subcortical motor mapping as an adjunct to increase safety during resection of a high-grade bAVM involving somatosensory cortex as well as cortical spinal tracts and visual tracts. After a bilateral craniotomy, they use direct cortical stimulation of the left motor cortex and subcortical stimulation using a suction stimulator to dynamically map motor tracts during the resection.

Department of Neurological Surgery, Thomas Jefferson University Hospital, Philadelphia, Pennsylvania, USA.
Study Design: Systematic Review and Meta-analysis.
Objective: This study aims to compare the efficacy and safety of surgical and endovascular treatments for SDAVFs.
Summary Of Background Data: Spinal dural arteriovenous fistulas (SDAVFs) result from an abnormal connection between the radiculomeningeal artery and the radicular vein, leading to venous hypertension and potential neurological damage.
Triple spinal dural arteriovenous fistula.
BMJ Case Rep
January 2025
Neurosurgery, ASST Grande Ospedale Metropolitano Niguarda, Milano, Italy.
Spinal dural arteriovenous fistulas (SDAVFs) are the most common type of spinal vascular malformations. Multiple SDAVFs are unusual and can occur either synchronously or metachronously, as reported in the literature. We report on the unusual case of a woman with three separate SDAVFs, which were surgically treated within the same setting; the postoperative course was characterised by unexplained repeated haematoma formation within the surgical sites.
