Sclerotherapy is a procedure which is used to treat blood vessels or blood vessel malformations (vascular malformations) and also, those of the lymphatic system. A medicine is injected into the vessels, to make them shrink. This procedure is for children and adults, with vascular or lymphatic malformations. In adults, it is often used to treat spider veins, smaller varicose veins and hemmoroids.
Sclerotherapy is often done under ultrasound guidance after venous abnormalities have been diagnosed with duplex ultrasound.
Injecting the unwanted veins with a sclerosing solution, causes the target vein to immediately shrink and then dissolve over a period of weeks, as the body naturally absorbs the treated vein. Sclerotherapy is a non-invasive procedure, taking only about 10 minutes to perform. The downtime is minimal, in comparison to an invasive varicose vein surgery.
Sclerotherapy is the “gold standard” and is preferred over laser for eliminating large spider veins and smaller varicose leg veins.
