Sclerotherapy is a microinjection procedure to treat spider veins. The procedure involves injection of a sterile solution (called a sclerosing solution) into the small veins using a very fine, thin needle. This solution irritates the vein lining causing it to undergo fibrosis and eventually disappear. Multiple veins can be injected at each session. The sclerosing solution used include either sotradecol, polidocanol or Sclerodex.
