subject: In Search of Eternal Youth [print this page] Sclerotherapy for Varicose and Spider Veins: A medical procedure used to eliminate varicose and spider veins, a solution (usually a salt solution) is injected directly into the vein which aggravates the blood vessel lining, causing it to swell and stick together, and the blood to clot. The procedure takes about 15 to 30 minutes. In due time, the vessel becomes scar tissue which fades from view. Generally, response time for spider veins is three to six weeks and three to four months for larger veins.
