Radiofrequency Ablation (RFA) is a minimally invasive treatment designed to address varicose veins and venous insufficiency by using controlled radiofrequency energy to close off problematic veins. During the RFA vein ablation, a thin catheter is guided into the affected vein under ultrasound guidance. The device delivers uniform heat, which causes the vein walls to contract, collapse, and seal shut. After treatment, blood is redirected to healthier veins, improving circulation and relieving symptoms such as swelling, aching, and visible bulging. https://www.usaveinclinics.com/treatments/varicose-vein-treatment/radiofrequency-ablation-rfa-treatment/
