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. Trial registration: This study was registered at http://www.chictr.org.cn (registration number: ChiCTR1900021409).
