What causes AVMs?
AVMs are present at birth (congenital) and appear to result from incomplete blood vessel development early in fetal life. Rarely, AVMs can run in families, so researchers suspect a genetic link is at work. Physicians do not attribute AVMs to environmental influences during pregnancy.
