Radiofrequency ablation (RFA) is a minimally invasive option for treating certain varicose veins and problems involving abnormal venous blood flow. During treatment, a catheter delivers radiofrequency energy to the targeted vein, causing it to close so blood can redirect through healthier veins. USA Vein Clinics offers personalized vein evaluations to help determine whether RFA may be appropriate for an individual patient. Specialists consider symptoms, medical history, and diagnostic results when developing a treatment plan.
