Sclerotherapy is a minimally invasive procedure administered by your healthcare provider to treat uncomplicated spider veins and uncomplicated reticular veins. The treatment involves the injection of a solution (Asclera) into affected veins.
Spider veins are very small, fine, red or blue veins that are less than 1 mm in diameter. They lie closer to the surface of the skin than varicose veins and may resemble a thin red line, tree branches, or spider patterns. Spider veins can be found on the legs and may cover a small or large area.
Asclera is a sclerosing agent that is injected into the vein. It works by damaging the endothelium, the inside lining of blood vessels. This causes blood platelets and cellular debris to attach to the lining of the vessels. Eventually, cellular debris and platelets cause the blood vessel to clot. Over time, the clotted vein will be replaced with tissue.
