Radiofrequency ablation (RFA) is a minimally invasive, FDA-approved treatment that effectively targets the root cause of varicose veins—not just the symptoms. Using controlled heat delivered through a thin catheter, RFA closes off damaged veins, rerouting blood flow to healthier vessels. The procedure requires no hospitalization, and most patients can resume normal activities immediately afterward. At USA Vein Clinics, our expert vein specialists use RFA to provide long-lasting relief from leg pain, swelling, heaviness, and other discomfort caused by vein disease.
