watershed infarction


wa·ter·shed in·farc·tion

infarction in a region of the cerebral cortex, the spinal cord, or a peripheral nerve where the distributions of nutrient arteries meet, or overlap; in these areas, tissue perfusion is most compromised when blood flow is decreased.
Infarction of a region that is peripheral to 2 arteries and susceptible to ischaemia. Watershed infarcts are often haemorrhagic, as restoration of the circulation allows blood to flow into damaged capillaries and ‘leak’ into the ischaemic tissue
