Endovenous laser therapy (EVLT)

  • Endovenous laser treatment of veins

Endovenous laser therapy (EVLT) is a technique for treating varicose veins which has the great advantage that it can be done under local anaesthetic without admission to hospital.

What is Endovenous laser therapy (EVLT)?

The laser probe is passed into the abnormal vein at the knee then passed under ultrasound guidance to the faulty valve in the groin which is the root of the problem.  The laser is then used to destroy the vein internally, without any incisions and only minor bruising.  The varicose veins themselves are then removed through a series of tiny cuts around 2 mm long, or else injected at a later stage.


If treatment is to be entirely under local anaesthetic, it is usual practice to spread the treatment over 1-4 sessions, depending on how extensive the veins are.  Alternatively the same result can be achieved in one sitting under a short general anaesthetic with discharge home the same day.

Are there any risks I should be aware of?

There is likely to be some bruising and a very low risk of infection or deep vein thrombosis. The chance of problem veins recurring is about 4%.
