A tangled collection of emergency blood vessels where there is an emergency communication between the arterial and venous systems. The afferents flow directly into the venous efferents without the normal resistance of an intervening capillary bed. They are mostly congenital. If big satis, they may manufacture a shunt of sufficient magnitude to raise the cardiac output. Common sites include; skin, liver, brain, brainstem and spinal cord, where they may reason headaches, seizures or bleeding (subarachnoid haemorrhage). See: arteriovenous fistula, cerebral arteriovenous malformations. Synonym: haemangioma
