Radiofrequency Ablation (RFA) is a minimally invasive procedure used to treat varicose veins. At USA Vein Clinics, RFA involves inserting a catheter into the affected vein, where radiofrequency energy is applied to heat and collapse the vein walls. This process seals the vein, redirecting blood flow to healthier vessels. The RFA varicose veins procedure is performed under local anesthesia, typically takes less than an hour, and allows patients to resume normal activities shortly after. RFA offers a high success rate with minimal downtime, making it a preferred option for varicose vein treatment. https://www.usaveinclinics.com/treatments/varicose-vein-treatment/radiofrequency-ablation-rfa-treatment/
