CT引导下奇神经节脉冲射频热凝术治疗肛门会阴部疼痛的临床观察

Treatment of anus perineal pain with pulsed radiofrequency thermocoagulation of ganglion impar

目的 评估在CT定位下奇神经节脉冲模式射频热凝术治疗肛门会阴部疼痛的疗效.方法 肛门会阴部疼痛的患者26例,在CT引导下行奇神经节穿刺,采用射频疼痛治疗系统行脉冲模式射频热凝治疗,射频温度定位42℃,持续120 s,连续3次.观察并记录术前、术后VAS评分.结果 与射频热凝术前VAS评分（5.92±1.38）相比,患者于治疗后1 h VAS评分（2.86±1.75）明显降低（P〈0.05）,术后第1日VAS评分（3.58.±1.63）和第3日VAS评分（3.21±1.28）均明显降低（P〈0.05）.结论 奇神经节脉冲射频热凝术治疗肛门会阴部疼痛安全有效.

Objective To evaluate the therapeutic effect of pulsed radiofrequency therrnocoagu- lation to the ganglion irnpar on the anus perineal pain. Methods The ganglion irnpar in 26 patients was therrnocoagulated by pulsed radiofrequeney with 42℃, 120s repeated 3 times in succession. VAS was evaluated before and after the treatment. Results Compared with pretreatment （5.92± 1.38）, VASin 1 hour （2.86t 1.75）, 1 day （3.58±1.63）, 3 clays （3.21± 1.28） （P±0.05） after pulsed radiofrequency therrnocoagulation were significantly decreased. Conclusion The pulsed radiofrequency thermocoagulation to ganglion irnpar is a good method with safety and effectiveness in the treat- ment of anus perineal pain.
