A vascular malformation is a type of congenial growth that is present at birth or a birthmark, which is made up of veins, capillaries, arteries or lymphatic vessels. There is many different types of vascular malformations, which have different medical names, according to which blood vessel is principally affected.

Vascular malformations are typically present at birth and grow at proportionality with the child. These malformations do not tend to involute spontaneously but may become more pronounced and apparent as the child grows.

What causes vascular malformations

Most vascular malformations tend to occur by chance. That said, these malformations can also be inherited, caused by an autosomal dominant gene. There is a 50/50 risk during each pregnancy that the gene will be passed from the parent to the child.

Venous malformations are a type of slow-flow vascular malformation, which are caused by abnormalities when the veins were developing. Venous malformations can occur anywhere on the body and face. They often appear as red or light-blue stains or swellings on the skin.

It is not uncommon for some patients with venous malformations to have blood clotting within the malformation. While some, more severe venous malformations can cause pain and discomfort due to the swelling, most venous malformations are not life-threatening.

Vascular malformation treatment

Treatment for vascular malformation depends on the type of malformation that requires treating. If a patient is seeking treatment for a capillary malformation or a stain on the skin, laser therapy can be an effective form of treatment.

Embolization, whereby the flow of blood into the malformation is blocked through the injection of material close to the lesion, is often used to treat arterial malformations.

Lymphatic and venous malformations are typically treated by the injection of a sclerosing mediation, which causes the channels to clot. Surgical options are also available with certain vascular malformations.
