What is EVLA?
Endovenous laser ablation (EVLA) is a minimally invasive varicose vein treatment. Laser energy heats the inner surface of the vein and closes it, redirecting blood to healthy veins. It is mainly used for widened, non-functioning main veins such as the great saphenous vein.
How is it done?
The procedure is performed under ultrasound guidance and local anaesthesia; the area is numbed so it cannot be felt.
- The vein to be treated is identified with Doppler ultrasound
- A thin catheter is inserted into the vein through the skin
- A laser fibre advanced through the catheter closes the vein from inside
- A compression stocking is applied afterwards
Who is it for?
It is considered for patients with symptoms and reflux in a main vein on Doppler ultrasound. Suitability depends on vein diameter, course and general health.
Recovery and possible side effects
Patients usually go home the same day; return to daily activities varies. Tenderness, bruising and tightness along the treated vein may occur. As with any procedure, side effects such as infection, bleeding, hardening under the skin or nerve irritation can rarely occur.
- Wear the compression stocking for the recommended period
- Walk regularly
- Attend the follow-up Doppler examination

Frequently asked questions
How long does EVLA take?
It depends on the number of veins treated; it is usually completed within an hour.
Is general anaesthesia needed?
No; it is usually performed under local anaesthesia.
What is the difference between EVLA and radiofrequency?
Both close the vein from inside with heat; the energy source differs. Which is suitable is decided at the examination.
