Sclerotherapy is a procedure 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, which makes them shrink. It is used for children and young adults with vascular or lymphatic malformations. In adults, Sclerotherapy is often used to treat varicose veins and hemorrhoids.
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 30 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 (telangiectasiae) and smaller varicose leg veins.
