Materials and Methods : Twenty-one patients (median age, 70 years) with spinal tumors underwent preoperative embolization. We injected embolus through a microcatheter placed proximally in the segmental arteries supplying the tumors. Surgical decompression was performed within 24 hours after embolization. We recorded tumor vascularity (classified into mild or increased), embolic agents used, complications related to the embolization, and intraoperative blood loss. Results : We successfully performed embolization with the particles for 63 of 69 (91%) segmental arteries supplying tumors. Complete embolization was achieved in 16 patients (76.2%). We injected lipiodol (median total dose, 1.5 ml) in 13 patients followed by gelatin sponge particles.  Twelve of the 13 patients had increased tumor vascularity. Median blood loss was 532 ml in the 14 patients with increased vascularity of tumor and 238 ml in the 7 with mild vascularity. One patient experienced transient sensory disturbance after embolization. Conclusion : This study revealed that efficacy of particle injection from the proximal portion of the segmental artery and feasibility of using lipiodol for embolization in hypervascular tumors.}, pages = {97--103}, title = {PREOPERATIVE EMBOLIZATION FOR SPINAL TUMORS USING GELATIN SPONGE PARTICLES WITH OR WITHOUT LIPIODOL}, volume = {47}, year = {2021} }
