Arteriovenous malformation (avm) is a vascular malformation (abnormal network of blood vessels) where arteries shunt directly into veins instead of going through a bed of capillaries this disfigurement of blood vessels lead to more blood flowing through, placing larger strains on the walls of the blood vessels the walls of.

An arteriovenous malformation is a tangled mass of abnormal blood vessels that connect arteries directly to veins in the brain or spinal cord normally, those systems are separated – the arteries carry blood from the heart through the brain tissue, and the veins then move it back to the heart under low pressure blood flows. An arteriovenous malformation, or avm, is an abnormal tangle of vessels in the brain or spinal cord in which one or more arteries are directly connected to one or more veins arteries carry blood from the heart to the tissues and veins take blood back from the tissues to the heart in an avm, the direct connection between.

An arteriovenous malformation is a localized or diffuse vascular lesion consisting of direct connections between arteries and veins, with the absence of the intervening capillary bed (network of tiny capillaries) this results in the abnormal flow of blood from the arteries (high flow) directly into veins (low flow) localized.
