ABSTRACT

Objectives

To evaluate the effect of vertebroplasty (VP) alone or combined therapy of radiofrequency ablation (RFA) with vertebroplasty on pain relief with visual analog scale (VAS) and Oswestry Disability Index (ODI) scores in vertebral hemangiomas.

Methods

Forty-six patients with hemangiomas were evaluated retrospectively: 20 males and 26 females were included. In group 1 (n = 25) only VP was performed, while RFA+VP were performed in the same treatment session in group 2 (n = 21). Radiological diagnosis was performed with X-ray, CT-scan and MRI images in all patients. The intensity of pain was assessed with the VAS together with the assesment of life quality with the ODI. The assesments were performed before, at first day, at first month and 6 months after treatment.

Results

There was no significant difference between mean preprocedural VAS and ODI scores, but a significant decrease was seen in postprocedural VAS and ODI scores between group 1 and 2, when compared with the preprocedural values. Although lack of a statistically significant difference in long term results, mean VAS score was 3.7 for group 1, while it was 1.8 for group 2, and the mean ODI score was 38 for group 1, and 22.48 for group 2 at 6th month assesment.

Discussion

Although minimally invasive percutaneous techniques are indicated as other modalities are ineffective or contraindicated, combining RFA with vertebral augmentation provide prevention of mechanical loading pain, and prevention of somatic pain in patients with spinal hemangiomas.

射频消融可改善椎体成形术治疗椎体血管瘤的有益效果：46例患者分析

摘要

目标

评估单独椎体成形术 (VP) 或射频消融 (RFA) 与椎体成形术联合治疗对椎体血管瘤疼痛缓解的效果，并采用视觉模拟评分 (VAS) 和 Oswestry 残疾指数 (ODI) 评分。

方法

回顾性评价了46例血管瘤患者：男性20例，女性26例。在第 1 组 ( n = 25) 中仅进行了 VP，而在第 2 组 ( n = 21)的同一治疗期中进行了 RFA+VP 。所有患者均通过 X 线、CT 扫描和 MRI 图像进行放射诊断。疼痛强度用 VAS 评估，同时用 ODI 评估生活质量。评估在治疗前、第一天、第一个月和治疗后 6 个月进行。

结果

术前平均 VAS 和 ODI 评分之间没有显着差异，但与术前值相比，第 1 组和第 2 组的术后 VAS 和 ODI 评分显着下降。尽管长期结果没有统计学上的显着差异，但在第 6 个月评估时，第 1 组的平均 VAS 评分为 3.7，第 2 组为 1.8，第 1 组的平均 ODI 评分为 38，第 2 组为 22.48。

讨论

尽管微创经皮技术被认为是其他方式无效或禁忌的，但将 RFA 与椎体增强相结合可预防机械负荷疼痛，并预防脊柱血管瘤患者的躯体疼痛。
