Interhemispheric Craniotomy for Resection of Thalamic Arteriovenous Malformation: 2-Dimensional Operative Video.

Arteriovenous malformations (AVMs) that occupy the deep brain structures are a formidable challenge during neurosurgical intervention. The heightened hemorrhage risk associated with these lesions necessitates intervention that often requires multimodal management. This patient presented following a large intraventricular hemorrhage and finding of a left thalamic AVM. The patient then underwent preoperative embolization and a frontal interhemispheric transcallosal approach for resection. The AVM was disconnected through standard sequential coagulation of feeding arteries and draining veins, followed by nidus excision. Postoperative angiography confirmed complete AVM resection, and the patient tolerated the procedure well. The patient gave informed consent for surgery and video recording. Institutional review board approval was deemed unnecessary. Used with permission from Barrow Neurological Institute, Phoenix, Arizona.
