Microsurgical Resection of Tumor of the Lateral Ventricle:
The surgical management of tumors of the lateral ventricles (LV) and the third ventricle (TV) remains a distinct challenge for neurosurgeons due to the deep and difficult-to-reach location and frequent involvement of adjacent critical neurovascular structures. An appropriate surgical approach should provide adequate operative working space with minimal brain retraction or brain transgression. To accomplish these goals, neurosurgeons may choose an approach that necessitates a longer distance to reach the tumor if it minimizes the amount of brain tissue that is resected or placed at risk by the approach. Furthermore, selection of the optimal approach to ventricular tumors depends on multiple other factors including the size of the ventricles and the tumor, the location of the arterial supply, pathological features of the tumor, and the surgeon’s experience. This video provides an overview of the open surgical operative corridors to the lateral tumors, highlighting the key surgical principles.
