Sclerotherapy was developed over 75 years ago and is at present one of the most prevalent treatments for spider and varicose veins. During treatment, a sclerosing agent is injected into the vein through a tiny needle. Upon injection, the solution replaces the blood in the vein generating irritation and ultimately corrosion to the vessel walls. The body then starts a natural healing process and the vein begins to decompose, shrink, and eventually disappear. Depending on the number of veins being treated in any given session, treatment can last anywhere from 15 to 45 minutes.
