数字减影血管造影引导下半月神经节射频热凝术治疗三叉神经第Ⅰ支痛的疗效

目的评价数字减影血管造影（DSA）引导下，采取精确控温法行半月神经节射频热凝术治疗三叉神经第1支痛的疗效和安全性。方法三叉神经第1支痛患者83例，在DSA引导下采取精确控温法行三又神经半月神经节射频热凝术，总结临床疗效及并发症，并记录随访2年的复发情况。结果优69例（83．1％），良11例（13．3％），一般2例（2．4％），无效i例（1．2％），优良率96．4％（80／83例），未见严重并发症发生。随访2年，1年内复发5例（6．0％），2年内复发13例（15．7％）。结论DSA引导下精确控温半月神经节射频热凝术是一种治疗三叉神经第工支痛安全、有效的方法。

Effect of radiofrequency thermocoagulation in semilunar ganglion on patients with the first branch of trigeminal neuralgia under the guidance of DSA

Objective To evaluate the effect and safety of radiofrequency thermocoagulation in semilunar ganglion on patients with the first branch of trigeminal neuralgia under the guidance of DSA. Methods Eighty-three patients with the first branch of trigeminal neuralgia were treated by semilunar ganglion radiofrequency thermocoagulation with precise temperature control under the guidance of DSA. The clinical efficacy, complications and the recurrent rate of 2 years followed up were recorded. Results 69（83.1%）, 11（13.3%）, 2（2.4%）and 1（1.2%）patients were graded as excellent, good, poor and ineffective effects respectively after the operation immediately. No serious complications were observed. 5（6.0%）and 13（15.7%）patients recurred within 1 year and 2 years respectively. Conclusion Semilunar ganglion radiofrequency thermocoagulation with precise temper- ature control is a safe and effective method in the treatment of the first branch of trigeminal neuralgia under the guidance of DSA.
