Navigation-assisted transcortical transventricular approach for paraventricular cavernoma: A technical note and review of the literature

Abstract

The surgery of paraventricular cavernoma remains a challenge for the neurosurgeon. Few approaches have been specially described for paraventricular cavernoma in literature. We present a patient with a symptomatic paraventricular cavernoma in the dorsal portion of the right lateral ventricles roof causing ventricular hemorrhage, and review his surgical approaches. This patient underwent a navigation-assisted transcortical transventricular approach resulting in a complete resection without any neurologic deficits. The approach allows a safe and effective resection of paraventricular cavernomas. Keywords: Paraventricular, Neuronavigation, Cavernoma, Transcortical transventricular approach
