Abstract：Objective To compare the clinical efficacy between radiofrequency ablation(RFA)and endovenous la-ser treatment(EVLT)combined with high ligation in the treatment of lower extremity varicose veins.Methods Totally 137 patients with lower extremity varicose veins were divided into RFA group(47 cases)and EVLT group(90 cases)ac-cording to different surgical methods.Patients in the RFA group received RFA treatment,while patients of the EVLT group received EVLT combined with high ligation.Intraoperative bleeding volume,perioperative hemodynamic indexes and length of hospital stay were compared between the two groups.The pain degree of the patients was evaluated by numeri-cal rating scale(NRS)at 24 h after surgery.The clinical efficacy was evaluated by venous clinical severity score(VCSS)and Kistner classification of deep venous valve function before and 6 months after surgery,respectively.Meanwhile,the occurrence of complications(such as saphenous nerve injury,subcutaneous hemorrhage and incision infection)within 6 months after surgery were observed.Results There were no statistically significant differences in intraoperative bleeding volume,perioperative hemodynamic indexes,postoperative 24-hour NRS,and length of hospital stay between the two groups(all P>0.05).However,VCSSs in both groups decreased at 6 months after surgery as compared with those before surgery(all P<0.05);compared with EVLT group,the VCSS was lower in the RFA group at 6 months after surgery.At the same time,there were no statistically significant differences in the Kistner classification or incidence of postoperative complications between the two groups before and 6 months after surgery(all P>0.05).Conclusion Compared with EV-LT combined with high ligation,RFA has a better clinical effect in the treatment of lower limb varicose veins and can effec-tively improve the degree of lower limb varicose veins.
