目的:探讨在CT引导下经小关节内侧缘穿刺,应用造影剂观察药物分布,准确行靶位注射胶原酶[1]治疗术后复发的腰椎间盘突出症的疗效。方法:10例经临床确诊为腰椎间盘突出症术后复发的患者,在CT引导下经小关节内侧缘入路将穿刺针直接刺入突出物内,注射欧乃派0.5 ml,观察药物分布情况后,注入胶原酶600 u。临床观察患者术后6~12个月的治疗效果,用改良的Macnab方法评价疗效。结果:10例患者穿刺针均顺利准确刺入突出物,造影剂均匀分布在突出物及盘内。治疗优、良率为100%,无严重并发症。结论: CT引导下穿刺造影,观察造影剂的扩散后,再行靶位注射胶原酶对于术后复发的腰椎间盘突出症,可以进一步提高治疗效果,减少并发症的发生。
