An injection is made into the spider vein area using a certain compound that causes the vein lining to collapse and become non-functional. This compound is called Aethoxysclerol and is available in two solutions of different strength, 0.5% or 1% depending on the size of the spider vein which of these solutions is used. Sometimes a foam-like substance is made out of the solution by mixing it with air. The vein continues to exist after the treatment but there is no blood running through the vein any longer. Frequently the skin around the area and the treated vein looks like it is embossed following this and it may take weeks or even months to see the final result. Patience is important in this connection. The treatment causes very little pain and takes about 20 minutes. Sometimes it is not enough to have a single treatment and the treatment will then have to be repeated after a number of months. Spider veins are sometimes treated at the commencement of the operation or when the individual returns after 6 months.
