Efficacy of Endovenous Laser Treatment Combined with Sclerosing Foam in Treating Varicose Veins of the Lower Extremities

Introduction This study aims to investigate the efficacy of incision-free endovenous laser treatment (EVLT) combined with sclerosing foam in treating varicose veins of the lower extremities. Methods A total of 140 patients (186 limbs) who underwent laser closure of the great saphenous vein + injection sclerotherapy were included in the present study. Preoperative information, intraoperative conditions, duration of the operation, and length of hospital stay were recorded in detail. During the 6-month follow-up, the closure of the trunk and branches of the great saphenous vein, postoperative pain, the recovery of ulcer and dermatitis, and postoperative complications were traced. Results All patients were treated with laser closure of the great saphenous vein and lauromacrogol injection. Twenty-six stage C6 limbs (lower extremity with ulcer) healed within 6 months, and the postoperative subjective pain disappeared after 1 month. In six patients, pigmentation in the surgical site did not completely disappear at 6 months after the operation. Saphenous nerve injury was found in five patients within 3 months after the operation, and all healed at 6 months after the operation. Conclusion EVLT combined with sclerosing foam is effective for treating varicose great saphenous veins.
