Interhemispheric Paracallosal Approach for an Arteriovenous Malformation of the Atrium: A Novel Technique

Background: Intraventricular lesions present a surgical challenge because of the complexity of the ventricular anatomy, various perforating arteries, and eloquent brain areas surrounding the system. The ventricular atrium is particularly challenging because of the cingulate gyrus, corpus callosum, optic pathways, and significant vascular structures. We present the case of a patient for whom we used a new surgical approach to reach a lesion in the ventricular atrium
