CT引导下神经根脉冲射频联合局部注射复方倍他米松治疗腰椎间盘突出症

目的探讨cT引导下神经根脉冲射频加神经根周围注射倍他米松治疗腰椎间盘突出症的疗效。方法2012年5月～2013年2月，对46例腰椎间盘突出症，在cT导引下精确定位神经根后，突出椎间盘节段神经根脉冲射频治疗，相应椎间孔内神经根周围注射倍他米松1ml＋生理盐水1ml。结果均顺利完成治疗，无并发症。术后6个月随访，按改良MaeNab标准：优28例，良12例，可4例，差2例，优良率87．O％（40／46），有效率95．7％（44／46）。结论神经根脉冲射频加神经根周围药物注射是腰椎间盘突出症的一种微创、有效、安全的治疗方法。

Treatment of Lumbar Intervertebral Disc Protrusion with CT-guided Transforaminal Pulsed Radiofrequency and Epidurai Injection of Betamethasone to the Nerve Root

Objective To observe the therapeutic effects of CT-guided transforaminal pulsed radiofrequency and epidural injection of betamethasone to the nerve root for the treatment of lumbar intervertebral disc protrusion. Methods From May 2012 to February 2013, 46 patients with lumbar intervertebral disc protrusion were treated. Under the CT guidance, the affected nerve roots were accurately positioned. Minimally invasive transforaminal pulsed radiofrequeney combined with epidural injection of 1 ml betamethasone and I ml normal saline were carried out. Results The procedure was completed smoothly in all the patients, without complications. Postoperative follow-up for 6 months showed, according to the modified MacNab standards, excellent results in 28 cases, good in 12 eases, fair in 4 eases, and poor in 2 cases, respectively, with an excellent-or-good rate of 87.0% （40/46） and an effective rate of 95.7% （44/46）. Conclusion CT-guided transforaminal pulsed radiofrequency and epidural injection with betamethasone to the nerve root appears to be an effective and relatively safe interventional technique for lumbar intervertebral disc protrusion.
