This study evaluated the feasibility, efficacy and safety of CT-guided percutaneous radiofrequency ablation in patients with spinal osteoid osteoma.
Two patients suffered spinal osteoid osteoma were treated with CT-guided percutaneous radiofrequency ablation under local anesthesia. Lesions located in sacral vertebrae and cervical vertebrae, which were adjacent to nerve root and spinal canal respectively. Tumors were treated under 90°C radiofrequency temperature lasting 4 minutes by an electrode placement. Visual analog scale was used to evaluate the pain improvement.
No complications were observed pre- and post-operation. Patients recovered to normal activities immediately and achieved complete pain relief in 24 hours. No symptoms were recurrent in 5 months and 4 months follow up. Mild scoliosis has been recovered in case 2.
CT-guided percutaneous radiofrequency ablation of spinal osteoid osteoma is safe, effective and has more clinical benefits. The long-term outcome needs further observation.
本研究评估了 CT 引导下经皮射频消融术治疗脊柱骨样骨瘤的可行性、疗效和安全性。
在局部麻醉下,2 例脊柱骨样骨瘤患者接受 CT 引导下经皮射频消融术治疗。病变位于骶骨和颈椎,分别邻近神经根和椎管。电极放置后,肿瘤在 90°C 射频温度下治疗 4 分钟。采用视觉模拟评分法评估疼痛改善情况。
术前、术后均未见并发症。患者术后即刻恢复正常活动,24 小时内完全缓解疼痛。5 个月和 4 个月随访时均无症状复发。第 2 例患者的轻度脊柱侧凸已恢复。
CT 引导下经皮射频消融术治疗脊柱骨样骨瘤安全、有效,具有更多的临床获益。远期疗效需要进一步观察。
