SP 297 OP 299 DO 10.1136/jnis.2010.003699 VO 3 IS 3 A1 Mario Ammirati A1 Konstantinos Spiliopoulos A1 Clara Raquel Epstein A1 Josue Gabriel A1 Eric C Bourekas YR 2011 UL http://jnis.bmj.com/content/3/3/297.abstract AB Preoperative direct percutaneous embolization has been very rarely used in hypervascular metastatic spinal tumors to decrease blood loss during the surgery. A patient is presented with solitary spinal metastasis due to renal cell carcinoma who underwent a two-stage spondylectomy. Transarterial tumor embolization with polyvinyl alcohol (PVA) particles and liquid coil placement, and percutaneous tumor embolization with PVA particles were used before the first and the second stage, respectively.
