The principle
In radiofrequency ablation (RFA) a thin catheter is placed in the varicose vein under ultrasound. Radiofrequency energy delivered through the catheter heats the inner surface; the vein closes and is gradually absorbed.
How it differs from laser
EVLA and RFA share the same principle: closing the vein from inside with heat. The main difference is the energy source. Which suits you is decided by examination and Doppler findings.
After the procedure
Patients can usually return to daily activities soon. Mild swelling and bruising may occur.
- Wear compression stockings for the recommended period
- Walk regularly
- Keep your legs raised when resting
