Understanding Arteriovenous Malformations (AVMs)

Arteriovenous malformations (AVMs) are abnormal tangles of blood vessels that pose significant health risks, potentially leading to strokes or hemorrhages. Typically, blood flows through the arteries and capillaries before returning through the veins, but in the case of AVMs, high-pressure blood can bypass capillaries and flow directly into fragile veins. This condition was highlighted through the experiences of veterans who developed AVMs after years of military service. These individuals provide a compelling narrative of the physical and psychological toll of living with such a condition.
