Arterial Venous Malformations
AVM’s are a rare condition that occur from maldevelopment of blood vessels.
They can occur anywhere on the body and are very variable in behavior depending on which type of blood vessels they originate from and where they are located.
It needs to be determined if the malformation is of venous, arterial, capillary, lymphatic or mixed origin. It then needs be determined if the lesion has high flow blood or low flow blood. One needs to assess symptoms and how dangerous they are - i.e. whether they are pressing on a vital organ or could compromise a vital organ and what their risk of growth, bleeding or blockage is.
AVM’s are typically very hard to treat. They require multiple treatments and are seldom curable. However, with a multidisciplinary team approach good outcomes can be achieved.
In depth imaging is mandatory to plan management and a radiologist, vascular surgeon and plastic surgeon are the key players in the team.
