Treatment for vascular malformations depends on the type of the malformation. Each type of malformation is treated differently. Laser therapy is usually effective for capillary malformations or port wine stains, which tend to be flat, violet or red patches on the face. Arterial malformations are often treated by embolization (blood flow into malformation is blocked by injecting material near the lesion).
Venous malformations are usually treated by direct injection of a sclerosing (clotting) medication which causes clotting of the channels. Most often, a combination of these various treatments is used for effective management of the lesion.
