Abstract

Objective: To evaluate the clinical effect of endovenous laser treatment (EVLT) for patients with varicose veins. Subjects and methods: Prospective study from July 2023 to September 2024. 51 legs of 39 patients were treated with 1470nm Laser. Patients were clinically classified by CEAP classification, clinical severity was assessed by VCSS scale. Ultrasound assessed the degree of venous insufficiency before intervention and monitored the effectiveness after intervention at 1 and 3 months. Results: Immediately after intervention, 100% of saphenous veins (including great saphenous veins and small saphenous veins) were completely occluded, with similar results after 1 and 3 months. CEAP classification improved significantly.  The clinical venous severity score (VCSS) decreased from 6.6 points before the intervention to 2.8 points and 0.33 points at 1 and 3 months (p<0.001). Only mild complications such as bruising and numbness along the treated veins occurred at a rate of 9.43% and 11.32%. There were no serious complications such as deep vein thrombosis, pulmonary embolism or skin necrosis. Conclusion: Endovenous LASER using 1470nm wavelength is a minimally invasive, safe intervention with many advantages such as fast return to daily activities, aesthetics and avoiding the risk of surgery.
