Radiofrequency Ablation (RFA) for Varicose Veins
Varicose veins that cause leg pain, heaviness, or swelling respond to radiofrequency ablation at Vein Center Doctor. Our board-certified specialists perform RFA as a minimally invasive outpatient procedure at 12 locations across New York and New Jersey.
RFA closes damaged veins from the inside using controlled thermal energy. The treatment takes approximately 45 minutes, requires only local anesthesia, and allows same-day return to normal activities.
What Is Radiofrequency Ablation?
Radiofrequency ablation is an endovenous procedure that uses radiofrequency energy to generate targeted heat inside a damaged vein. A thin catheter delivers thermal energy to the vein wall, causing it to collapse and seal shut. The body redirects blood flow through healthy veins, eliminating reflux that causes varicose veins.
Vein Center Doctor uses the ClosureFast catheter system to perform RFA. This system delivers consistent thermal energy in 20-second cycles, sealing each vein segment precisely. Clinical studies demonstrate a 93-percent closure rate at five years following the procedure.
The sealed vein is gradually reabsorbed by surrounding tissue. No surgical incision is required, and the single catheter entry point needs only a small adhesive bandage after treatment.
What a Radiofrequency Ablation Session Looks Like
An RFA appointment at Vein Center Doctor begins with duplex ultrasound mapping so your specialist can visualize the target vein in real time. Local anesthesia numbs the skin near the catheter entry point, typically just below the knee, and a thin ClosureFast catheter is guided into the damaged vein.
The catheter delivers radiofrequency energy in 20-second cycles that heat and seal each segment of the vein wall. The full procedure takes about 45 minutes, uses only local anesthesia, and most patients describe the sensation as mild pressure rather than pain. A compression stocking is applied at the end and you return to normal activities the same day.
The RFA Treatment Process at Vein Center Doctor
Ultrasound-Guided Preparation
Your specialist uses duplex ultrasound to visualize the target vein in real time. Local anesthesia numbs the treatment area around the catheter insertion site.
Catheter Insertion and Positioning
A thin radiofrequency catheter enters the vein through a small puncture, typically near the knee. Ultrasound guidance positions the catheter tip at the precise treatment start point within the saphenous vein.
Thermal Energy Delivery
The catheter delivers controlled radiofrequency energy in 20-second cycles. Each cycle heats a segment of the vein wall to the temperature needed for permanent closure. The specialist withdraws the catheter segment by segment until the entire affected length is sealed.
Post-Treatment Assessment
Vein Center Doctor performs an immediate ultrasound to confirm the treated vein is closed. A compression stocking is applied, and your specialist reviews recovery instructions before you leave the office.
Benefits of Radiofrequency Ablation
Outpatient Procedure with No Downtime
RFA eliminates varicose veins without hospital admission. Vein Center Doctor performs the entire procedure in-office, and most patients return to work and daily routines the same day.
Minimal Discomfort During Treatment
Local anesthesia at the catheter site is the only numbing needed for RFA. Patients describe the sensation as mild pressure rather than pain. The thermal energy delivery itself is typically not felt.
High Long-Term Success Rate
Clinical evidence supports RFA's durability, with published closure rates exceeding 93 percent at five years. Vein Center Doctor has completed more than 10,000 successful vein procedures using this and other minimally invasive techniques.
Cosmetic and Symptomatic Relief
RFA addresses both the appearance of varicose veins and the underlying cause of symptoms. Leg heaviness, swelling, and skin changes improve as blood flow normalizes through healthy vessels.

Frequently Asked Questions About RFA
Is radiofrequency ablation covered by insurance?
Most insurance plans cover RFA when it is medically necessary. Vein Center Doctor verifies your benefits during your free vein screening and explains coverage before treatment begins.
How long does an RFA procedure take?
A single RFA session at Vein Center Doctor takes approximately 45 minutes. Patients spend an additional 15 to 30 minutes for pre-procedure preparation and post-procedure assessment.
Does RFA leave scars?
RFA uses a single catheter puncture that typically heals without a visible mark. No surgical incisions are made during the procedure.
Can RFA treat spider veins?
RFA targets larger varicose veins caused by venous reflux. Spider veins are treated with sclerotherapy, which Vein Center Doctor also offers at all locations.
What happens to the treated vein after RFA?
The sealed vein is gradually reabsorbed by the body over several weeks. Blood automatically reroutes through healthy veins, restoring normal circulation.
