Clinical assessment of endovenous thermal ablation combined with concomitant phlebectomy for the treatment of lower limb varicose veins with or without poor glycemic control

This study aimed to investigate the clinical results of endovenous thermal ablation combined with stab phlebectomy for unilateral varicose veins based on diabetic management.The study reviewed 501 patients who underwent endovenous thermal ablation combined with stab phlebectomy for unilateral varicose veins, including 337 nondiabetics (control group) and 164 diabetics. Diabetics with hemoglobin A1c ≥7% were classified as the poor glycemic control group, and hemoglobin A1c <7% as the good glycemic control group. Surgical outcomes were assessed by Venous Clinical Severity Score. The Chronic Venous disease quality of life Questionnaire was used to assess the quality of life.Lower limb varicose veins can be treated successfully with endovenous thermal ablation combined with stab phlebectomy in patients with or without poor glycemic control, accompanied by a significant improvement in health status. For patients with initial varicose veins (preoperative Venous Clinical Severity Score <10), the results revealed satisfactory improvements in Venous Clinical Severity Score and quality of life among the control, poor glycemic control, and good glycemic control groups. Patients with advanced varicose veins (preoperative Venous Clinical Severity Score ≥10) also showed an obvious amelioration concerning venous symptoms and quality of life. However, the extent of improvement varied among the 3 groups. Patients subjected to advanced varicose veins with the condition of poor glycemic control exhibited a less desirable improvement in postoperative health conditions compared with the control and good glycemic control groups, especially in edema relief and ulcer healing.Endovenous thermal ablation combined with stab phlebectomy is safe and effective in the treatment of varicose veins with or without poor glycemic control. Clinical attempts at hemoglobin A1c management may contribute to improved clinical outcomes in patients with advanced varicose veins.
