Radiofrequency Ablation (RFA)
A gentle, catheter-based treatment that closes diseased leg veins with controlled heat — no surgery, no stitches, no downtime.
What Is Radiofrequency Ablation?
Radiofrequency ablation, or RFA, is one of the most established treatments for varicose veins and chronic venous insufficiency. Instead of surgically removing a diseased vein, RFA closes it from the inside.
A thin catheter is guided into the refluxing saphenous vein — the main superficial vein of the leg — under real-time ultrasound. Controlled radiofrequency energy gently heats the vein wall so it seals shut. Your blood simply reroutes through nearby healthy veins, and the closed vein is gradually absorbed by the body.
Published studies report closure rates well above 90% for RFA, which has largely replaced vein stripping surgery. At Avancé Vein Care, Dr. Tadepalli personally performs every RFA procedure in our Sparta office.
Who It's For — and Who It's Not For
RFA is designed for patients whose duplex ultrasound shows reflux — blood flowing backward — in a saphenous vein. If you have aching, heaviness, swelling, cramping, or visible varicose veins traced back to a refluxing saphenous vein, RFA is often an excellent option. It is usually covered by insurance when medically necessary, and we verify your coverage before treatment.
RFA is generally not the right choice when:
- The diseased vein is very twisted or close to the skin, where a heat-free option such as Varithena® may be safer and more practical.
- Your concern is purely cosmetic spider veins, which are treated with sclerotherapy instead.
- You have an active deep vein clot or certain other conditions your evaluation would identify.
The only way to know is a proper ultrasound evaluation — which Dr. Tadepalli performs himself at every consultation.
What to Expect
Before
Your visit begins with a consultation and a duplex ultrasound that maps exactly where your veins are refluxing. If RFA is right for you, insurance is verified and pre-authorization handled before anything is scheduled. No referral needed, no surprise billing.
During
On treatment day, plan for a 45–90 minute visit. The skin is numbed, and the catheter enters the vein through a tiny opening — no incision, no stitches. Dr. Tadepalli then places tumescent local anesthesia, a dilute numbing solution, around the vein. This keeps you comfortable and protects the surrounding tissue while the radiofrequency energy seals the vein in short, controlled segments. You are awake and can talk with us the entire time.
After
A compression stocking is applied, and you walk out the same day — walking is encouraged. Most patients drive themselves home. Back to life the same afternoon.
Recovery
Recovery from RFA is typically brief. Most patients resume everyday activities the same day and return to work within a day or two, depending on the job. We generally recommend wearing a compression stocking for a short period, walking regularly, and avoiding heavy straining and long hot baths for the first several days.
Mild soreness, tightness, or a pulling sensation along the treated vein is common in the first week or two and usually settles on its own. A follow-up ultrasound confirms the vein has closed properly.
Risks & Considerations
RFA has a strong safety record, but no procedure is risk-free. Results vary from person to person. The most common effects are temporary: bruising, tenderness, tightness along the vein, and occasional skin pigmentation. Less common risks include numbness or nerve irritation near the treated segment (more relevant in the lower leg), superficial phlebitis, and — rarely — a deep vein clot (DVT) or heat-related injury. Careful ultrasound guidance and proper tumescent anesthesia are what keep these risks low, which is one reason every procedure here is physician-performed.
If your anatomy makes heat-based treatment less suitable, alternatives such as VenaSeal™ adhesive closure or ultrasound-guided sclerotherapy may be recommended instead. Choosing between RFA and laser ablation (EVLA) depends on your specific vein anatomy.
"RFA lets us close the vein that's actually causing the problem — gently, precisely, and in under an hour. My patients are often surprised at how uneventful it feels."— Dr. Satish Tadepalli, MD, MPH, DABVLM, RPVI
