A thin catheter delivers radiofrequency energy inside the vein, heating the wall and collapsing it. Blood is rerouted to healthy veins.
Radiofrequency Ablation
Radiofrequency Ablation is a catheter-based procedure that treats varicose veins by using heat energy to seal off malfunctioning veins, improving circulation and appearance.
Area(s)
Large superficial veins (e.g., great or small saphenous vein).
Duration
Procedure time is around 90 minutes.
Frequency
Once.
What to Expect
How We Do It
- Vein is numbed with local anesthetic.
- RFA catheter is inserted under ultrasound guidance.
- Heat is applied gradually as catheter is withdrawn.
Side Effects
Mild bruising, tightness, or skin tenderness. Rare risk of numbness or inflammation.
Time to Full Effect
Most patients see vein closure within 1–2 weeks, and symptom relief in 3–6 weeks.
Questions? We’ve got answers.
Is RFA safe?
Yes — it’s FDA-approved and widely used for varicose vein treatment.
What’s the recovery like?
Most patients return to normal activities within 24 hours.
Does it hurt?
There may be some pressure or warmth, but local anesthesia keeps it comfortable.
Will I need time off work?
Not usually — many patients go back to work the next day.
How long do results last?
The treated vein is permanently closed. Lifestyle changes help prevent new ones.
- Avoid lotion or oils on the legs.
- Wear loose clothing.
- Bring compression stockings to the appointment.
- Stop blood thinners if advised.
- Wear compression stockings for 1–2 weeks.
- Avoid prolonged sitting or standing.
- Light walking daily is encouraged.
- No heavy lifting for 5–7 days.
