Preoperative Embolization in Surgical Treatment of Spinal Metastases: Single-Blind, Randomized Controlled Clinical Trial of Efficacy in Decreasing Intraoperative Blood Loss

Preoperative embolization in patients with symptomatic spinal metastasis independent of primary tumor diagnosis did not reduce intraoperative blood loss and allogeneic RBC transfusion significantly but did reduce the surgery time. A small reduction of intraoperative blood loss was shown in hypervascular metastases.
