Clinical Efficacy of Endovenous Radiofrequency Ablation (RFA) for Superficial Varicose Veins of the Lower Extremities

Abstract

Objective. To investigate the clinical efficacy of intravenous radiofrequency ablation (RFA) in the treatment of patients with superficial varicose veins of lower extremities. Methods. From January 1, 2021, to January 1, 2022, 62 patients with superficial lower extremity varicose veins were selected and divided into two groups according to the treatment plan. 31 patients underwent high saphenous vein ligation and dissection as control. Thirty-one patients received RFA treatment as the experimental group. The operation-related indicators, clinical efficacy, and postoperative complications were compared. Results. The intraoperative blood loss in the experimental group was significantly less than that in the control group. The clinical efficacy of the experimental group was significantly better than that of the control group. The incidence of postoperative complications in the experimental group was lower than that in the control group. Conclusion. RFA has a good clinical effect in the treatment of patients with superficial lower extremity varicose veins, with less postoperative complications, and has a high therapeutic value.
