摘要
目的:探讨注射臭氧治疗腰椎间盘突出症时臭氧在椎间盘内的分布类型对疗效的影响。材料和方法:CT引导下使用22G细针穿刺椎间盘,注入60μg/ml的臭氧(O3)10～20ml。根据CT表现,将O3在椎间盘内的分布分为5种类型。同时分析突出物局部有无O3分布。定期随访,分析O3在椎间盘内的分布类型对疗效的影响。结果:技术成功率100%,无并发症发生。随访3～12个月,总有效率为78.2%,O3在椎间盘内分布:Ⅰ型21.4%,Ⅱ型和Ⅲ型均为7.2%,Ⅳ型14.3%,Ⅴ型50%。有效组中,突出物局部有O3分布占80.3%。结论:椎间盘内注射O3是腰椎间盘突出症的简便、微创、有效治疗手段。O3在椎间盘内的分布类型对疗效有一定的影响,突出物局部有无O3分布是影响疗效的重要因素之一。
Purpose： To investigate the impact of the ozone distribution patterns intradiscally on the efficacy of the CT-guided percutaneous ozone injection for the treatment of lumbar disc herniation. Materials and Methods： All patients were lying prone on the CT scanning table. Under CT guiding, the 22G puncture needles were inserted into the intended disc. For each herniated disc, 10 -20ml ozone with a concentration of 60% was injected into the disc. According to the CT appearances, the distribution pattern of ozone within the disc were divided into five types. Meanwhile, whether ozone distributed within the bulge area was also analyzed. The ozone distribution pattern intradiscally in relation to the effectiveness were investigated contrastively. Results： The technical successful rate was 100%. No any severe complications occurred. The patients were followed up varied from 3 to 12 months. The total effective rate was 78.2%. The percentage of different ozone distribution pattern intradiscally was as follows ： 21.4% of type Ⅰ , 7.2% of type Ⅱ and type Ⅲ respectively, 14.3% of type Ⅳ, and 50% of type Ⅴ. In effective group, the ozone distributed within the extruded portion of the disc in 80.3%. Conclusions： （1） CT- guided percutaneous ozone injection intradiscally is a simple, mini-invasive, and effective method for the treatment of the lumbar disc herniation; （2） The effectiveness is, to some extent, influenced by the ozone distribution pattern intradiscally, however, whether the ozone distributed within the extruded portion of the disc is the key factors influencing the efficacy.
