Preoperative Embolization of Skull Base Meningiomas: Safety and Efficacy

Preoperative embolization of skull base meningioma prior to resection is a technique employed by some to reduce intraoperative blood loss and aid in ease of resection. Risks of preoperative embolization include neurological deficit, ischemia, and hemorrhage. We present a retrospective analysis of patients undergoing resection of skull base meningiomas between January 2020 and August 2022. We compare patients undergoing preoperative embolization with those that did not, evaluating complications from embolization and surgery as well as blood loss and transfusion requirement.
