AbstractArteriovenous malformations (AVMs) are complex vascular lesions that can pose significant risk for spontaneous hemorrhage, seizures, and symptoms related to ischemia and venous hypertension.1 Microsurgical management of AVMs requires a deep understanding of the surrounding anatomy and precise identification of the lesion characteristics. We demonstrate the use of augmented reality in the localization of arterial feeders and draining veins in relation to bordering normal structures (Video 1). A 66-year-old man presented with several episodes of severe right frontal headaches. Magnetic resonance imaging revealed an AVM along the right frontal pole. Subsequent computed tomography angiography demonstrated arterial supply from the right anterior cerebral artery with venous drainage to the superior sagittal sinus. Due to the size, noneloquent location, and superficial pattern of venous drainage, the patient elected to proceed with microsurgery. A virtual planning platform was used in preparation for surgery. Augmented reality integrated with neuronavigation was used during microsurgical resection. Postoperative angiography showed complete resection of the AVM. The patient was discharged home on postoperative day 3 with no complications. He remains neurologically well at 4 months of follow-up.Copyright © 2024. Published by Elsevier Inc.
