半月节立体定向毁损治疗三叉神经痛(附124例报告)

目的 探讨CRW立体定向导航系统以及三维CT在三叉神经半月节射频热凝术中的应用价值.方法 广东省第二人民医院自2007年7月至2009年12月共收治124例原发性三叉神经痛患者,均采用CRW立体定向系统辅助下经皮穿刺卵圆孔,再在三维CT辅助下进针到达半月节切迹,方波刺激及预毁损确认穿刺到位后,采取逐渐加温的方式进行毁损.结果 124例患者均穿刺成功,无穿刺副损伤所致并发症.一次穿刺成功89例(71.8%),二次穿刺成功33例(26.6%),2例(1.6%)因颅底骨质结构有变异,经多次穿刺成功.术后即刻总体有效率为98.4%.术后出现患侧面部麻木感即浅感觉减退87例(70.2%),1例患者出现角膜炎(0.8%),未出现复视、咀嚼无力、张口困难等并发症.所有患者随访3月～2年,复发7例(5.6%).结论 采用立体定向导航系统及三维CT重建可以大大提高穿刺卵圆孔的准确性,减少并发症:个体化穿刺策略的制定可以进一步确保疗效,提高治愈率.

Stereotactic and three -dimensional -CT assisted percutaneous radio -frequency thermocoagulation for 124 cases of primary trigeminal neuralgia

Objective To investigate the value of CRW stereotactic navigation system and three-dimensional-CT in the radiofrequency thermocoagulation for primary trigeminal neuralgia.Methods One hundred and twenty-four patients with primary trigeminal neuralgia were treated with percutaneous radio-frequency thermocoagulation with the aid of CRW stereotactic system and three-dimensional CT. Results All of 124 patients were punctured successfully without any complications. Eighty-nine patients (71.8%) were punctured successfully at nce,33 patients(26.6%)were punctured successfully at twice. Because of the variation of the skull bottom, 2 patients (1.6%) were punctured successfully at many times. The effective rate of thermocoagulation is 98.4%. Eighty-seven patients (70.2%) appeared facial sensory decline and 1 (0.8%) appeared keratitis after operation; no such complications as diplopia, masticatory atonia and difficulty in opening mouth appeared. Seven patients (5.6%) relapsed after follow-up for 3 months to 2 years. Conclusion A stereotactic and CT reconstruction can greatly improve the accuracy of puncturing on the foramen ovale, reduce the complications and help to adopt an individualized puncture strategy, which can ensure the effectiveness and increase the cure rate.
