Arteriovenous malformations

Dr Bita Abbasi and Dr Donna D'Souza et al.

An arteriovenous malformation (AVM) are characterized by an abnormal leash of vessels allowing for arteriovenous shunting. They can occur anywhere in the body but have a predilection towards the head and neck.  There is a direct arteriovenous communication with no intervening capillary bed. They can be congenital or acquired.
