watershed stroke causes
Watershed Stroke. Watershed strokes. are usually the result of poor blood flow to the brain from occlusion of the arteries in the neck (from atherosclerosis) or periods of poor cardiac function, such as during a heart attack.
Indeed, hypotension may result in low flow or so-called watershed infarctions, and more significantly, it may augment injury from other causes. Due to the limitation of retrospective design, the study did not review the link between postoperative hypotension and the occurrence of stroke.
