射频热凝联合臭氧消融术治疗腰椎间盘突出症疗效观察

Clinical Observation of Radio Frequency Thermal Coagulation Combined with Ozone Ablation for Lumber Disc Herniation Treatment Directed by CT

目的观察CT引导下经皮射频热凝联合臭氧消融术治疗腰椎间盘突出症患者的疗效。方法回顾分析我院2009~2012年收治的腰椎间盘突出症患者46例,男34例,女12例,手术时年龄35~70岁,平均45.3岁,均在CT引导下进行腰椎间盘射频热凝联合臭氧消融术,采用疼痛视觉类比评分（VAS）和止痛药使用评分评估术后疗效。结果所有患者均顺利完成手术,手术平均时间（50±10）min,每个患者均为一个节段的病变,节段位于L4-5／L5-S1,纤维环破裂者34例,未破裂者12例,随访6个月~2年,术前VAS评分平均（8±0.2）分,术后2d降低到（2±0.8）分,末次随访时为（2.5±0.8）分。各指标术后2d及末次随访时与术前比较均有显著性差异（P〈0.01）。影像学复查示术后突出物明显缩小。结论 CT引导下经皮射频热凝联合臭氧消融术治疗腰椎间盘突出症是一种安全、有效、远期疗效确切的脊柱外科治疗技术。

Objective This study aimed to investigate clinical effects of RFTC（radio frequency thermal coagulation）combined with OA（ozone ablation）for LDH（lumber disc herniation）treatment directed by CT.MethodsFourty-six LDH patients（34male,12female）registered in Aosidi hospital were treated with RFTC combined with OA directed by CT from 2009 to 2012,and were followed up retrospectively,meanwhile the curative effect were recored through Visual Analog Scale（VAS）and Painkiller Taking Scale（PTS）.Results Surgery for All patients were successful,average surgery time was 50±10min.All patients had a diseased disc,the location at L4-5／L5-S1,34 of them had annular disruption,the other 12 had not.The followed-up period varied from 6months to 24 months.Tthe VAS was decreased from（average 8±0.2）pre-operation to（2±0.8）at 2days after operation with a significant difference（P〈0.01）.The reduction of protrusion was significant by iconology examination.Conclusion RFTC combined with OA directed by CT for LDH is a safe,effective,long-term positive therapy for spinal surgery.
