超声联合C臂对比CT引导胸椎背根节脉冲射频治疗带状疱疹后神经痛的回顾研究

Retrospective clinical study of ultrasound combined with C-arm versus CT-guided thoracic dorsal root ganglion pulsed radiofrequency in the treatment of herpetic neuralgia

摘要:

目的：比较超声结合C臂和CT引导胸椎背根节脉冲射频治疗带状疱疹后神经痛(PHN)的作用。方法：采用回顾性分析,将94例PHN接受胸椎背根节脉冲射频治疗患者,按穿刺影像引导方式分为超声联合C臂组和CT引导组,每组47例。两组于治疗前、治疗后1天、3月及6月进行疼痛视觉模拟评分法 (VAS) 评分的并进行镇痛有效率的对比,并比较两组在穿刺时间、穿刺次数、射线次数及经济成本方面的差异。结果：两组病人的VAS评分及镇痛有效率在各个时间点比较差异均无统计学意义(P>0.05)。CT组在穿刺时间、射线次数及经济成本等方面明显高于超声组(P < 0.05)。结论：与CT引导比较,超声结合C臂用于胸椎背根节射频治疗PHN,具有更快捷、低辐射及低经济成本的优势。

Abstract:

Objective: To compare the effects of ultrasound combined with C-arm and CT-guided thoracic dorsal root ganglion pulsed radiofrequency in the treatment of Post Herpetic Neuralgia (PHN). Methods: By retrospective analysis, 47 patients with PHN who received thoracic dorsal root ganglion pulsed radiofrequency treatment were divided into ultrasound combined C-arm group and CT-guided group according to the image-guided method, with 47 cases in each group. Before treatment, 1 day, 3 months and 6 months after treatment, the pain was scored by visual analogue scale (VAS) and the analgesic efficiency was compared between the two groups. Differences in the times of punctures, times of radiation and economic costs. Results: There was no significant difference in the VAS score and analgesic efficiency between the two groups at each time point (P>0.05). The CT group was significantly higher than the ultrasound group in terms of puncture time, times of rays and economic cost (P < 0.05). Conclusion: Compared with CT guidance, ultrasound combined with C-arm for radiofrequency treatment of PHN in the thoracic dorsal root ganglion has the advantages of faster, lower radiation and lower economic cost.
