Sclerotherapy is a treatment for removal of spider veins and smaller varicose veins. The veins are injected with a sterile chemical sclerosant such as Asclera. The sclerosant irritates the lining of the vessel which makes it become inflamed and eventually fade away. This procedure may require more than one treatment but is extremely effective. For best results, we recommend that patients wear support stockings for a few weeks after the treatment. For this reason, sclerotherapy is a popular fall and winter treatment in our climate.
