Varicose Veins

These are bulging veins that lie just beneath the skin (superficial veins). They occur when the walls of a vein are weak or damaged or if the valves in the vein that normally stop the blood from flowing backwards are impaired, resulting in pooling of the blood and stretched veins. Besides being unattractive, varicose veins can be painful and cause inflammation or ulceration.

The following different types of treatments are available for varicose veins:

RFA/EVLA - Radio Frequency Ablation or Endovenous Laser Ablation

Radio Frequency Ablation or Endovenous Laser Ablation is a technique for destroying the larger faulty veins. This procedure was developed in 1999 and worldwide, hundreds of thousands of patients have been treated with RFA/EVLA. The procedure is performed under local anaesthetic thus avoiding the unnecessary risk of a general anaesthetic. It is “Walk in, Walk out” technique and you can return to work the same day if you wish.

UGS – Ultrasound Guided Sclerotherapy

Ultrasound Guided Sclerotherapy (UGS), also commonly known as injection treatment, is a non-surgical treatment for varicose veins that are not suitable for Endovenous Ablation. The treatment involves injecting a special solution into the veins, using ultrasound guidance that causes the vein wall to become irritated and collapse. The veins dissolve and disappear over three to six months as the body absorbs them. Ultrasound Guided Sclerotherapy (UGS) is particularly effective for recurrent varicose veins.  Good results have been achieved with closure rates close to 90% at one year.


Sclerotherapy is a non-surgical way to shrink away those unsightly spider veins, preventing them from causing you any discomfort or embarrassment. Sclerotherapy treats spider veins by injecting a special sclerosant solution into the veins, damaging, shrinking, collapsing and dissolving them, helping to ease your mind from the stress that spider veins can bring and improve the cosmetic appearance of your legs.
