目的探讨数字血管减影机(DSA机)引导下半月神经节射频温控热凝术治疗三叉神经痛的疗效和安全性。方法66例患者DSA机引导下准确定位后,在异丙酚全身麻醉下行射频温控热凝治疗,目标温度设定85℃,持续时间均为120s。结果66例患者穿刺成功率100%,术后疼痛即刻消失率100%,随访5个月～3年3例复发;并发角膜炎2例,头痛5例,并发症发生率0.11%。结论DSA机引导下半月神经节射频温控热凝术治疗三叉神经痛安全、准确、客观、有效,易于普及。
Objective To investigate the efficacy and safety of digital angiographic subtraction (DSA) -based guided radiofrequency thermocoagulation in the treatment of trigeminal neuralgia in the second half of the ganglion. Methods 66 cases of patients under the guidance of DSA accurate positioning, under the general anesthesia of propofol underwent radiofrequency thermocoagulation treatment, the target temperature set 85 ℃, the duration of both 120s. Results 66 cases of patients with successful puncture rate of 100%, 100% immediately after the disappearance of pain, followed up for 5 months to 3 years 3 cases of recurrence; 2 cases of keratitis, headache in 5 cases, the incidence of complications was 0.11%. Conclusion DSA machine guided the second half of the ganglion radiofrequency thermocoagulation for trigeminal neuralgia safe, accurate, objective, effective, easy to popularize.
