Sclerotherapy is a non-operational treatment for varicose veins, spider veins and vein extensions. Veins are injected with the sclerosing agent, which is given in liquid form, and for the large veins can be used form of foam. This leads to fibrosis and permanent vein atresia. Immediately after injection pressure dressing is assumed, and further healing process leads to total obliteration of the lumen of blood and its fibrosis.
The treatment is short (usually a few minutes), it is virtually painless and requires no limitation of physical or professional activity.
