Watershed Infarct Secondary to Severe Carotid Stenosis

A watershed stroke or watershed infarct is defined as a brain ischemia that is localized to the vulnerable border zones between the tissues supplied by the anterior, posterior and middle cerebral arteries. The actual blood stream blockage/restriction site can be located far away from the infarcts.

Severe reduction of perfusion secondary to severe left carotid stenosis was responsible in this case.
