Arteriovenous Malformation (AVM) is not contagious and cannot be spread from person to person through contact, bodily fluids, or proximity. It is a structural abnormality in the circulatory system that develops during fetal development and carries no risk of transmission to family members, caregivers, or friends. What is the underlying cause of Arteriovenous Malformation (AVM)? An Arteriovenous Malformation (AVM) occurs when a tangle of abnormal blood vessels connects arteries and veins, bypassing the normal capillary system.

An Arteriovenous Malformation (AVM) occurs when a tangle of abnormal blood vessels connects arteries and veins, bypassing the normal capillary system. Medical research indicates that most cases are congenital, meaning they arise due to developmental errors during embryonic growth. While the exact trigger for this error is often unknown, it is not caused by viruses, bacteria, or any infectious agent. Currently, there is no evidence that environmental factors or lifestyle choices after birth cause an Arteriovenous Malformation (AVM) to form.
Because the term "malformation" can sound clinical or associated with systemic illness, some individuals may mistakenly fear that Arteriovenous Malformation (AVM) is an infectious or communicable condition. It is important to clarify that AVM is a localized vascular issue. There is absolutely no risk to those living with, touching, or caring for someone diagnosed with this condition. Stigma often arises from a lack of public awareness, but you should feel fully confident that Arteriovenous Malformation (AVM) poses no health threat to your community.
While the condition is not infectious, researchers have identified certain factors that may influence its presentation:
