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.
术前直接经皮栓塞术在治疗血供丰富的转移性脊柱肿瘤中很少应用，以减少手术中的出血量。本文报道了 1 例因肾细胞癌引起的单发脊柱转移患者，该患者接受了两阶段的脊柱切除术。在第一阶段和第二阶段手术前，分别采用经动脉肿瘤栓塞术（聚乙烯醇[PVA]颗粒和液体线圈放置）和经皮肿瘤栓塞术（PVA 颗粒）。
