Microsclerotherapy is a technique used to treat spider veins or thread veins of the legs. It is a relatively straightforward procedure which involves injecting a liquid into the veins.
It is suitable for use on thread veins on the legs or body. Small thread veins on the face are better treated with Electro Surgery, or laser. Microsclerotherapy is the most preferable treatment for thread veins in your leg.

Minimally invasive treatment for spider veins and varicose veins

For varicose veins of the legs the traditional treatment was surgery, which is still carried out. The problem with surgery is that it’s quite an extensive operation; there are side effects and risks associated with it. The biggest problem is that there is a good chance of recurrence, that these veins will come back again. Personally I would not want my varicose veins to be treated surgically.

Newer non-surgical techniques have been developed over the last decade. The commonest of these is Endovenous Laser Ablation (EVLA/EVLT). Instead of stripping the veins physically out of the body which happens in surgery, Endovenous Laser Ablation destroys the veins where they actually are.
