Sclerotherapy

Sclerotherapy is a procedure used to treat blood vessel malformations and also malformations of the lymphatic system. A medicine is injected into the vessels, which makes them shrink. It is used for children and young adults with vascular or lymphatic malformations. 

Sclerotherapy is the most common treatment for improving the appearance of varicose and spider veins on the legs. It is also performed to treat symptoms caused by these conditions, such as aching, swelling and burning. Sclerotherapy involves injecting a chemical solution directly into the varicose or spider vein.
