Sclerotherapy is a procedure used to eliminate varicose veins and spider veins of the legs. The procedure involves injection of a solution directly into superficial veins. The solutions cause irritation and damage to the lining of the blood vessels, causing them to collapse and ultimately fade from view.
There are basically 3 possible solutions that are widely used in the United States. These include hypertonic saline (a concentrated salt solution), sodium tetradecyl sulfate (Sotradecol®), and polidocanol (Asclera®).
