Neuroendovascular Procedures for Skull Base Neoplasia

Abstract

Background and Purpose: Neuroendovascular procedures are performed in skull base neoplasia with the objective of achieving preoperative embolization to increase the safety of surgical procedures by limiting intraoperative hemorrhage, reduce the need for transfusion, increase visibility in the surgical field, and shortening hospitalization length. Embolization should typically be reserved for lesions with numerous, deep, surgically inaccessible tributaries, where a significant bleed is anticipated, or the tumor is surrounded by critical neurovascular structures.
