What is sclerotherapy and what is it used for?
This is the injection of a solution into an abnormal vein through a small needle. The solution that is injected destroys the vein wall, with the vein then scarring and shutting down. As opposed to laser treatment, which is termed thermal ablation, sclerotherapy is a form of chemical ablation. Sclerotherapy is typically performed on the smaller varicose vein branches, reticular veins, and spider veins.
