Objective To compare the current therapeutic effects between endovenous radiofrequency treatment and conventional surgery for lower limb chronic venous insufficiency (CVI) ,and summarize operative skills and clinical value of endovenous radiofreq uency treatment on CVI .Methods Data of 45 limbs of 41 patients treated by endovenous radiofrequency treatment (endovenous ra-diofrequencytreatmentgroup)and20limbsof20patientsbytraditionalsurgery(traditionalsurgerygroup)wereanalyzedandcom-pared in terms of operation time ,postoperative pain ,postoperative hospitalized duration ,complications ,and one-year recurrence rate .Results Endovenous radiofrequency treatment group had less postoperative pain and shorter postoperarive hospitalized dura-tion than traditional surgery group(P<0 .05) .The operation time had no significant differences between two groups (P>0 .05) . The two groups had few complications and had no recurrence in one year .Conclusion As a minimally invasive treatment for vari-cose veins ,endovenous radiofrequency treatment has less trauma ,rapid recovery ,safe and effective ,and it is worthy to be recommen-ded .%目的：比较静脉腔内射频和传统手术治疗下肢慢性静脉功能不全（CVI）的近期疗效，总结下肢CVI射频腔内闭合技术的操作技巧及临床应用价值。方法对41例45条患肢行静脉腔内射频治疗（静脉腔内射频治疗组）和20例20条患肢行传统高位结扎剥脱手术（传统手术组）的临床资料进行统计分析，比较两组的手术时间、术后疼痛、术后住院时间、并发症、1年复发率共5项指标的情况。结果静脉腔内射频治疗组在术后疼痛、术后住院时间方面明显优于传统手术组（P＜0．05）；而手术时间与传统手术组比较差异无统计学意义（P＞0．05）；两组术后并发症少，术后1年随访均无复发病例。结论静脉腔内射频治疗是一种创伤小、术后恢复快、安全有效的微创治疗CVI的方法，有重要的临床应用价值。
