三维CT导向卵圆孔精确定位射频热凝治疗三叉神经痛研究

目的:探讨三维CT引导卵圆孔定位在三叉神经痛射频热凝治疗中的应用。方法:对20例三叉神经痛病人,取仰卧位,采用Hartel前入路穿刺法,应用三维CT引导以明确卵圆孔位置,并调整穿刺针的方向和深度,穿刺卵圆孔定位成功后,行温控射频热凝治疗。结果:穿刺针均位于卵圆孔内,治疗后疼痛即刻缓解,无严重并发症发生。结论:三维CT引导卵圆孔定位,提高了卵圆孔穿刺的成功率和精确性,弥补了徒手穿刺的缺陷,增加了操作的安全性,降低并发症发生,可供临床推广应用。

A STUDY OF 3D-CT GUIDED OVAL FORAMEN LOCATIONS IN RADIOFREQUENCY THERMOCOAGULATION FOR TRIGEMINAL NEURALGIA

Objective: To observe the clinical effects of 3D-CT guided oval foramen locations in radiofrequency thermocoagulation for trigeminal neuralgia. Methods: 3D-CT guided oval foramen locations was performed in 20 patients via dorsal position using Hartel' s technique, so that the direction and position could be defined for trigeminal neuralgia. Results: All needles located in oval foramen. Pain was alleviated immediately with no serious complication occurred in all of the patients. Conclusion: 3D-CT guided oval foramen locations can increase the successful rate of puncture, enhance the safety and reduce the incidence rate of complication, can be popularized in the future.
