摘要：More than 60% of spinal metastases are hypervascular tumors. Intraoperative bleeding often occurred in the surgery for spinal metastases in the past. Therefore, it is necessary to take some preoperative interventions to reduce intraoperative bleeding. Preoperative embolization may be considered in order to decrease the risk of hemorrhage and improve the outcomes. Embolization in the patients with spinal metastases can be performed through the angiographic catheter. When such embolization is performed carefully, the complication rate becomes low. Preoperative transarterial embolization for hypervascular spinal tumors has been extensively used at present, and is considered to be a highly effective adjuvant technique in reducing intraoperative blood loss. Meanwhile, the feasibility and safety of the surgical procedure can be increased and better surgical outcomes can be achieved. Adequate embolization of tumor nutritious blood vessels and early surgery after embolization ( in hours ) seem to determine the curative results of the procedure. Hypervascular spinal tumors are major indications of arterial embolization. One of the main contraindications of preoperative embolization for spinal metastases is a shared vascular pedicle between the anterior spinal artery and the quasi embolism. In general, embolization should be carried out within 72 hours before the surgery. The sooner the excision is performed, the less the blood loss is. After 72 hours, hemorrhage control is decreased due to arterial recanalization, arteriectasia or establishment of collateral circulation. In this paper, the indications and contraindications of preoperative transarterial embolization, the choice of emboliaztion agents, operation time, operation method, curative results and complications are reviewed.
