Sclerotherapy is a technique, which involves the injection of a very small amount of solution into the veins. This causes the walls of the veins to stick together, empty of blood and ultimately disappear. Sclerotherapy is by far the most successful way of removing thread veins on the legs. The needles used are very fine and most people are unaware that the treatment is being performed.
What are the side effects of treatment?
Minor side effects do occur in some people. Slight swelling and redness around the vein may appear soon after the injection has been given. This disappears over two to three days. The veins themselves darken as they are shrivelling and can take anything from two to eight weeks to clear. Sometimes small bruises are apparent just under the skin at injection sites. In some people a brown pigmentation mark may develop either at the site of the bruise or the original vein. This staining can in some instances take several months to completely disappear.
