Tangled
The tangled intersection of arteries (red) and veins (blue) is an arteriovenous malformation (AVM), the anatomical abnormality that led to Dr. Taylor’s stroke. An AVM is essentially a clump of blood vessels that results when there are no capillaries linking arteries to veins. Sometimes the vessels of an AVM burst under pressure, allowing blood to pool in the brain; this is called a hemorrhagic stroke (American Stroke Association, 2012; National Institute of Neurological Disorders and Stroke, 2015).
