Sclerotherapy for Spider Veins

A common form of treatment for spider veins is sclerotherapy. This is an in-office procedure where veins are injected with a sclerosing solution using small needles, which causes them to collapse and fade from view. The procedure typically improves not only the cosmetic appearance, but also the associated symptoms. During sclerotherapy, the affected leg is elevated to drain blood, and the sclerosing agent is injected into the spider vein. The procedure normally ranges from 15 to 30 minutes, depending on how many spider veins are treated. This form of spider vein treatment may cause minimal discomfort, and the chemical that is injected can cause a feeling of burning or cramping for a few minutes in the area of the injection site. Treatment may be extended over a few sessions to derive the maximum benefit, depending on the extent of the spider veins.​
