What is radiofrequency ablation?
Radiofrequency ablation (RFA) is a minimally invasive varicose vein treatment. Heat produced by high-frequency radio waves is delivered to the inner surface of the vein; the vein closes and is gradually absorbed by the body.
How is it done?
- The patient is assessed and local anaesthesia is applied
- A thin catheter is placed in the varicose vein under ultrasound
- Radiofrequency energy is delivered to the inner vein wall through the catheter
- A compression stocking is applied and walking is advised
Who is it for?
It is considered for patients with widened, visible varicose veins and reflux in a main vein on Doppler ultrasound. The doctor decides the suitable method for each patient.
Recovery
Patients can usually get up after the procedure and return to daily activities soon. Mild swelling and bruising may occur and usually fade over time.
- Keep your legs raised when resting
- Wear the compression stocking for the recommended period
- Attend the follow-up examination
