The embolization of hypervascular spinal tumors preoperatively has shown to be a worthwhile adjunctive procedure to minimize the elevated risks associated with surgical resection, such as intraoperative blood loss and its associated complications. Resection of these hypervascular tumors is necessary for local tumor control, reduction in patient-reported pain, improved neurological functioning, and spinal stability. This adjunctive procedure has been associated with improved surgical outcomes and easier facilitation of surgical resection. As such, we provide a review of the current literature examining the employment of this technique. Specifically, this article (a) reviews the techniques of embolization, with anatomical considerations of the arterial framework of the spinal network; (b) relativizes and outlines the post-embolization management of spinal tumor resection; (c) provides a critical outlook on the reported benefit of preoperative embolization before surgical resection with support from clinical studies in the literature; and (d) discusses the efficacy and reliability of provocative testing and post-procedural management and follow-up. Ultimately, a thorough and updated review of preoperative spinal tumor embolization and its clinical benefits will summarize the current fund of knowledge and encourage future research toward continued improvements in patient outcomes for those needing to undergo surgical resection of spinal lesions.
