CT引导下神经根周围阻滞配合胶原酶溶核治疗腰椎间盘突出症

目的探讨CT引导下神经根周围阻滞对胶原酶溶核治疗腰椎间盘突出症所致近期疼痛加重的预防效果.材料和方法对21例腰椎间盘突出症的患者采取CT引导下胶原酶溶核治疗的同时加神经根周围阻滞术,观察患者1个月内腰腿痛的变化情况.结果疼痛减轻率76.2%(16/21),14.3%(3/21)无明显变化,9.5%(2/21)出现疼痛加重,加重者经口服止痛药均能忍受疼痛.结论CT引导下神经根周围阻滞能有效预防由胶原酶溶核治疗腰椎间盘突出症所致的近期疼痛加重,操作简便、安全.

CT-guided Collagenase Chemonucleolysis of Lumbar Disc Herma tion Combming with Perineural Root Block

Purpose:To explore the precaution efficiency of early stage aggravated pain induced by collagenase chemonucleolysis via using perineural root block. Materials and Methods:21 cases of lumbar disc herniation were treated by the therapy of collagenase chemonucleolysis combing with perineural root block, the changes of lumbago and leg pain were observed within one month. Results:Pain was relieved in 75.7% (16/21), unchanged in 14.3% (3/21), aggravated in 9.5% (2/21)who tolerated the pain only need of taking some ordinary analgesic drugs. Conclusion:Perineural Root Block shows satisfactory precaution effects of early stage aggravated pain induced by collagenase chemonucleolysis, easy manipulation and safety.
