The purpose of this study was to investigate the safety and efficacy of CT-guided percutaneous cryoablation for the treatment of osteoid osteoma in adults.
A retrospective case series over a 30-month period involved 10 consecutive adult patients (nine male and one female patients; mean age, 27.9 years; age range, 16-49 years) who underwent CT-guided percutaneous cryoablation for management of osteoid osteoma. Clinical and technical success was evaluated with postprocedure MRI at 4-5 weeks and with digital numeric pain scores taken before and immediately after the procedure, as well as at primary follow-up (4-10 weeks; average, 5 weeks) and secondary follow-up (23-29 weeks; average, 24 weeks).
Clinical and technical success rates were 100%. Average digital numeric pain scores were 7.4 before the procedure, 1.5 after procedure, 0.5 at the primary follow-up, and 0.3 at secondary follow-up. No minor or major complications were noted during the procedure, recovery period, primary follow-up, or secondary follow-up.
CT-guided percutaneous cryoablation is safe and effective in the treatment of osteoid osteoma in adults.
本研究旨在探讨 CT 引导下经皮冷冻消融治疗成人骨样骨瘤的安全性和疗效。
回顾性病例系列研究，共纳入 10 例连续成年患者（9 例男性和 1 例女性；平均年龄 27.9 岁；年龄范围 16-49 岁），均接受 CT 引导下经皮冷冻消融术治疗骨样骨瘤。术后 4-5 周行 MRI 评估临床和技术成功，术前、术后即刻、初次随访（4-10 周；平均 5 周）和二次随访（23-29 周；平均 24 周）时行数字疼痛评分。
临床和技术成功率均为 100%。术前数字疼痛评分为 7.4，术后即刻为 1.5，初次随访时为 0.5，二次随访时为 0.3。手术过程、恢复期、初次随访和二次随访期间均未发生轻微或严重并发症。
CT 引导下经皮冷冻消融术治疗成人骨样骨瘤安全有效。
