CT引导下臭氧消融术联合神经根阻滞治疗腰椎间盘突出症

目的 探讨CT引导下臭氧消融术联合神经根阻滞治疗腰椎间盘突出症的穿刺的准确性、治疗的安全性以及疗效.方法 选择200例腰椎问盘突出症患者,随机分为2组:A组100例,单纯行臭氧消融术,B组:100例,臭氧消融术联合神经阻滞治疗,治疗前1d、治疗后3d、3、6个月测定疼痛视觉模拟评分(VAS),治疗总有效率来评估治疗效果(比较常用的是MacNab法评价疗效).结果 两组患者治疗后3d、3、6个月VAS值较治疗前1 d明显降低(P<0.01或P<0.05),B组治疗后3d,3、6个月VAS值较A组明显降低(P<0.05),A组治疗后3d、3、6个月总有效率分别为90%、85%、79%,B组治疗后3d、3个月、6个月总有效率分别为100%、90%、85%,B组治疗后3d、3个月、6个月总有效率较A组提高.结论 CT引导下臭氧消融术联合神经根阻滞治疗腰椎间盘突出症,近期(3 d)总有效率100%,提高中远期(3、6个月)总有效率.

The therapeutic effect analysis of lumbar intervertebral disc protrusion using ozone ablation and selected nerve root block by CT

Objective To explore the clinical effect of ozone ablation and nerve root block in the treatment of lumbar intervertebral disc protrusion. Methods Two hundred patients with lumbar disc herniation were divided into two groups:100 patients in group A were treated with ozone ablation; 100 patients in group B were treated with ozone ablation combined with nerve root block. The therapeutic effect was evaluated by comparing the value of VAS and total effective rate of therapy at the first day before treatment, and at the 3rd day ,3rd month and 6th month after treatment. Results The values of VAS in two groups at the 3rd day,3rd month and 6th month after treatment were remarkably lower than those at the first day before treatment (P<0.05 or P<0.01). The values of VAS in B group at the 3rd day ,3rd month and 6th month after treatment were lower significantly than those in group A (P<0.05 or P<0.01). The total effective rate of therapy at the 3rd day,3rd month and 6th month after treatment was 90% ,85% and 79% in group A,and 100% ,90% and 85% in group B respectively. The total effective rate of therapy at the 3rd day ,3rd month and 6th month after treatment in group B was higher than in group A. Conclusion The total effective rate of therapy by ozone ablation combined with nerve root block treating lumbar intervertebral disc protrusion under CT at the 3rd day after treatment was 100% , and that at the 3rd month and 6th month after treatment was increased.
