Endovenous Laser Treatment, also known as endovenous laser ablation, endovenous laser therapy, or EVLT, is a minimally invasive, office-based treatment for varicose veins. It uses ultrasound guidance to direct laser energy into diseased, malfunctioning veins. Endovenous Laser Treatment can alleviate painful, uncomfortable, and visible vein symptoms like leg swelling, cramping, aching, itching, and skin discoloration. At USA Vein Clinics, we specialize in performing Endovenous Laser Treatment and a range of other non-surgical vein treatments. Once laser energy is delivered, the targeted veins collapse and seal closed. Afterward, blood flow is redirected to healthy, surrounding veins.
