螺旋CT引导半月节脉冲射频治疗三叉神经痛的远期疗效观察

Prospective Efficacy of Pulsed Radiofrequency Guided with Spiral CT on Trigeminal Neuralgia: Long-term Observation

目的观察螺旋CT引导下半月节穿刺脉冲射频治疗三叉神经痛的远期疗效。方法 100例原发性三叉神经痛患者分为研究组(脉冲射频组,n=44)和对照组(射频热凝组,n=56)。比较治疗前,治疗后0.5年、1年、2年时的疼痛数字模拟评分(NRS)及临床疗效。结果治疗后1年内两组NRS无显著性差异,但2年后研究组复发率明显高于对照组(P<0.01)。结论半月节脉冲射频治疗三叉神经痛安全有效,但远期疗效欠佳。

Objective To investigate the prostecdtive therapeutic efficacy of pulsed radiofrenquency and radiofrequency thermocoagulation of the Gasserian ganglion guided with spiral CT on trigeminal neuralgia.Methods 100 patients with idiopathic trigeminal neuralgia were treated with pulsed radiofrenquency or radiofrequency thermocoagulation of gasserian ganglion.The numeric rating scales（NRS） of pain were recorded before and 0.5 year,1 year,and 2 years after treatment.Results There was no difference in NRS within 1 year,but the recurrence rate was high in the paitents accepted pulsed radiofrenquency 2 years later（P0.01）.Conclusion Pulsed radiofrenquency of the gasserian ganglion is safe and effective on trigeminal neuralgia,but poor in long-term outcome.
