Preoperative Embolization of Skull Base Meningiomas: Impact on surgical results

Meningiomas are considered the most common benign brain tumors.1 One of the most challenging anatomical locations are the skull base meningiomas. Special considerations are encountered, such as the rich blood supply, the nearby vital neurovascular structures and the narrow surgical corridor.2-4 Early devascularization of the lesion is considered the cornerstone step in meningioma surgery, aiming to facilitate tumor dissection from the surroundings and to minimize intraoperative blood loss.5,6
