Abstract: Objective：To compare the clinical effectiveness of radiofrequency ablation（RFA）combined with local point stripping and endovenous laser treatment（EVLT）combined with high saphenous vein ligation in the treatment of varicose veins of lower extremity.Methods：120 patients with varicose veins of lower extremity were treated with intravascular radiofrequency ablation combined with local point stripping（60 cases，group R）and EVLT combined with high saphenous vein ligation（60 cases，group E）.Duration of the operation，intraoperative blood loss，total hospitalization cost，length of hospital stay，and postoperative complications（pain，swelling，local hematoma，skin infection，Incidence of burn，saphenous nerve injury）of the patients were compared.Results：There was no significant difference in the operation time between the two groups.However，there were more bleeding in the group E than in the group R，longer hospital stay，higher cost of hospitalization，and higher postoperative complications.The difference was statistically significant（P<0.05）.Conclusion：Intracavitary radiofrequency ablation combined with local point stripping is superior to endovenous laser treatment combined with high saphenous vein ligation，and it is safe，with less intraoperative bleeding，quick recovery，and low treatment cost，the advantages of less postoperative complications.
