Sclerotherapy

Sclerotherapy is the non-surgical treatment of varicose and spider veins. Varicose veins are diseased veins that have become permanently dilated. They occur because valves within the lumen of certain veins become incompetent and as a result they allow the blood to flow backwards distending the vein, and in time, causes the vein to stretch and become dilated. The sclerotherapy is done by injecting a small amount of solution (called a sclerotic agent) into a varicose vein. The sclerosing solution irritates the lining of the vein and causes causes the vein to become inflamed and later on will dry up. The vein is replaced with a fibrous tissue that is reabsorbed by the body and disappears.
