Arteriovenous Malformations are abnormal structures arising from arteries and veins. These can be quite difficult to treat. They can also be found in association with other malformations or as part of a syndrome. They may first appear as a red patch but enlarge with time. They grow in proportion to the child’s growth and at puberty they may enlarge even further. The overlying tissue enlarges with time and if involving a limb, there will be an enlargemt of the whole limb.

Arteriovenous malformations are investigated by duplex ultrasound, angiography and MRI.

Larger symptomatic lesions are treated with embolisation.
