Laser Ablation

Laser ablation for varicose veins (EVLA)

Endovenous ablation of varicose veins uses energy to cauterise (burn) and close varicose veins. It is used to help ease symptoms such as pain, swelling, and irritation. Laser energy is used to heat the vein in order to destroy it. EVLA is safe, less invasive than surgery, and leaves virtually no scars.  

A fine tube (catheter) is passed through the skin near the knee and then threaded up the diseased long saphenous vein. The catheter is attached to a laser that heats the end of the catheter. The heat seals the walls of the vein so that no blood can flow through it. The operation can be done under general or local anaesthetic. We normally use local anaesthetic, since this allows a more rapid recovery after treatment.

How is EVLA different to surgery treatment?

Varicoe vein surgery usually requires a cut in the groin to tie off the vein, after which it is removed by a stripping device. This can cause significant bruising. EVLA avoids the need for a cut in the groin and there is minimal bruising, so people who have EVLA can usually return to normal activity sooner than those who have standard treatment.

Is EVLA better than surgery?

The main advantage of EVLA is, that after the operation there is very little discomfort and bruising compared to conventional surgery. In the long-term an excellent cosmetic outcome can be expected from either technique. There is a similar risk of recurrence following either procedure.

Is everyone with varicose veins able to have EVLA?

No. Some people have large, winding veins, that are not suitable. Recurrent varicose veins after previous surgery are often unsuitable for EVLA. We will be happy to arrange a consultation to discuss whether your veins are suitable for EVLA. About 70% of people with varicose veins can be treated with EVLA.

Is EVLA all I need for my veins?

EVLA will remove the major superficial veins, including the LSV and anterior thigh veins. It is, however, usually necessary to have the bulging veins around the calf removed. We usually treat these veins with foam injections at the same time as the EVLA treatment.
