Radiofrequency Ablation (RFA)

Radiofrequency Ablation, or RFA, is a minimally invasive treatment that closes a refluxing vein using controlled radiofrequency heat. It treats the underlying source of venous reflux rather than only the visible surface veins.

When a refluxing vein is closed, blood is redirected through healthier veins. This can reduce pressure in the varicose vein network and may improve symptoms related to venous reflux.

• Saphenous vein reflux
• Varicose veins related to venous reflux
• Bulging veins fed by refluxing source veins
• Leg heaviness, aching, swelling, fatigue, or throbbing caused by reflux
• Chronic venous insufficiency patterns confirmed by ultrasound

A catheter is placed into the target vein under ultrasound guidance. Local anesthesia is applied. The catheter delivers controlled radiofrequency energy to the vein wall, causing the vein to collapse and seal closed.

RFA is performed in the office. Most patients walk soon afterward. Compression, walking, and follow-up ultrasound may be recommended.

Mild soreness, tightness, bruising, or tenderness can occur. Patients are usually encouraged to stay active with walking and avoid prolonged sitting or standing early in recovery.

RFA is often covered when symptoms and ultrasound findings meet insurance criteria. Coverage varies by plan.
