How can sclerotherapy help with treating varicose and spider veins?

ANSWER

Spider veins cannot be removed through surgery. Sometimes, they disappear when the larger varicose veins feeding the spider veins are removed. Remaining spider veins also can be treated with sclerotherapy. Sclerotherapy uses a fine needle to inject a solution directly into the vein. This solution irritates the lining of the vein, causing it to swell and the blood to clot. The vein turns into scar tissue that fades from view. Some doctors treat both varicose and spider veins with sclerotherapy. Today, the substances most commonly used in the U.S. are hypertonic saline, sodium tetradecyl sulfate (Sotradecol) and aethoxysklerol/Asclera (Polidocanol).
