Overview

Vascular malformation is a blood vessel abnormality. There are many types, but the most common is arteriovenous malformation. Clinical behavior and growth cycles vary widely and it may cause clinical and aesthetic problems. International Society for the Study of Vascular Anomalies (ISSVA) has classified vascular malformation into simple malformation, combined malformation, those of major named vessels, and those associated with other anomalies. Simple malformation have been divided further into capillary malformation, venous malformation and lymphatic malformation.
