Abstract

Rationale and Objectives

The aim of the current study was to evaluate the feasibility and effectiveness of CT-guided microwave ablation (MWA) in the treatment of osteoid osteomas (OO).

Materials and methods

Data from 59 consecutive patients who underwent percutaneous CT-MWA for OO treatment were examined in the current retrospective study. The period of this study spanned from January 2021 to May 2023 at a single institution. The study involved an evaluation of clinical and radiological characteristics, procedural data, Visual Analog Scale (VAS) pain scores, complication incidences, as well as clinical and technical success rates. Statistical analyses were performed by using the Wilcoxon test with Bonferroni correction, Friedman, Spearman, Mann–Whitney U test.

Results

59 patients with an average age of 17.31 ± 8.53 years underwent CT-guided MWA for the treatment of OO. The procedure demonstrated a high success rate, with 96.6% of cases achieving both technical and clinical success. However, recurrence was observed in two patients (3.4%) at the three-month follow-up. These cases were successfully managed with a second MWA procedure. The median VAS pain scores reported by the patients was significantly improved post-procedure: from 8.64 ± 1.14 before treatment to 0.63 ± 0.98 in the first month, 0.41 ± 1.02 in the third month, and 0.15 ± 0.45 in the sixth month. Only one patient (1.7%) experienced a minor complication; no major complications were recorded in this study.

Conclusion

CT-guided percutaneous MWA is a minimally invasive and a highly effective and safe approach for the treatment of OO.

经皮 CT 引导微波消融治疗骨样骨瘤：单中心经验。

依据和目的：本研究旨在评估CT引导下微波消融（MWA）治疗类骨瘤（OO）的可行性和有效性：本回顾性研究对59例连续接受经皮CT-MWA治疗OO患者的数据进行了检查。本研究的时间跨度为 2021 年 1 月至 2023 年 5 月，研究机构为一家。研究涉及临床和放射学特征、手术数据、视觉模拟量表（VAS）疼痛评分、并发症发生率以及临床和技术成功率的评估。统计分析采用带 Bonferroni 校正的 Wilcoxon 检验、Friedman 检验、Spearman 检验和 Mann-Whitney U 检验：59名平均年龄为（17.31±8.53）岁的患者在CT引导下接受了MWA治疗OO。手术成功率很高，96.6%的病例获得了技术和临床成功。然而，有两名患者（3.4%）在三个月的随访中出现复发。这些病例通过第二次 MWA 手术成功治愈。患者报告的 VAS 疼痛评分中位数在术后有了明显改善：从治疗前的 8.64 ± 1.14 降至第一个月的 0.63 ± 0.98、第三个月的 0.41 ± 1.02 和第六个月的 0.15 ± 0.45。只有一名患者（1.7%）出现了轻微并发症；本研究未记录到重大并发症：结论：CT引导下经皮MWA是治疗OO的一种微创、高效、安全的方法。
