An arteriovenous malformation (AVM) is a congenital disorder characterized by a complex, tangled web of arteries and veins. An AVM may occur in the brain, brainstem, or spinal cord and is caused by abnormal development of blood vessels. (Source: excerpt from NINDS Arteriovenous Malformation Information Page: NINDS)
Abnormal, tangled collections of dilated blood vessels that result from congenitally malformed vascular structures in which arterial afferents flow directly into venous efferents without the usual resistance of an intervening capillary bed. A common type is the congenital arteriovenous fistula (ARTERIOVENOUS FISTULA /congenital). For arteriovenous malformations in the brain, INTRACRANIAL ARTERIOVENOUS MALFORMATIONS is available.
