Four patients with a solitary vertebral metastasis from a renal cell carcinoma presented with acute spinal cord or nerve root compression. Because of the markedly hypervascular nature of the metastases it was decided to palliate the lesions by transarterial catheter embolization. The embolization reduced the venous blood pool within the tumors, resulting in progressive neurological improvement often lasting for 12 weeks or more. With such palliation, surgical decompression may be obviated, postponed, or at least made manageable.
4例肾细胞癌孤立性椎体转移患者出现急性脊髓或神经根压迫。由于转移灶具有明显的高血管性，决定通过经动脉导管栓塞术缓解病变。栓塞减少了肿瘤内的静脉血池，使神经功能逐渐改善，通常持续12周或更长时间。通过这种缓解措施，可避免、推迟手术减压，或至少使其易于处理。
