神经导航系统引导下卵圆孔定位穿刺在半月神经节射频热凝术治疗三叉神经痛中的作用

摘要

目的:分析在神经导航系统的引导下,通过卵圆孔定位穿刺,在半月神经节行射频热凝术治疗三叉神经痛的疗效.方法:原发性三叉神经痛26例纳入研究.所有患者术前均采用CT技术对其颅脑进行薄层扫描,通过工作站给予颅底重建,分析测定卵圆孔并选其为靶点,采用导航棒辅助,对其进行定位穿刺,行半月神经节射频热凝治疗.结果:本组26例患者穿刺均一次性即成功,术中平均阻抗500 Ω,其运动刺激平均值0.88 V,感觉刺激平均值0.53 V.本组患者视觉模拟评分(VAS)术前为(9.3±0.5)分,术后为(1.5±0.9)分,差异有统计学意义(P＜0.05).根据BNI评分,术后“疗效显著”19例,“有效”5例,“无效”2例.结论:半月神经节射频热凝治疗原发性三叉神经痛的过程中,借助神经导航对卵圆孔进行定位穿刺,有助于提高卵圆孔穿刺准确率,提高疗效.%Objective:To analyze the clinical effect of treatment for trigeminal neuralgia with radiofrequency catheter ablation guided by neuronavigation system.Methods:Twenty-six patients with trigeminal neuralgia were enrolled.LTC scanning was used to get the relevant brain imaging data to reconstruct the skull base and to locate the foramen ovale.Guided by the neuronavigation system,radiofrequency catheter ablation was used to treat trigeminal neuralgia.Results:All the puncture operations were succeed for the first time.The average impedance was 500 Ω,the average value of the motion stimulation was 0.88 V and the average value of sensory stimulation was 0.53 V.The visual analogue scale (VAS) was (9.3±0.5) before and (1.5±0.9) after operation (P＜ 0.05).After operation,19 out of 26 cases completely recovered.Conclusion:It is a good way to treat trigeminal neuralgia with radiofrequency catheter ablation guided by neuronavigation system.
