Ischemic stroke results from interruption of blood flow to the brain and accounts for 80% to 85% of all strokes.The interruption can be the result of a thrombotic or embolic event.Thrombosis can form in large vessels (large-vessel thrombotic strokes)or small vessels (small-vessel thrombotic strokes).Embolic sources include the heart (cardioembolic strokes)and atherosclerotic plaques in larger vessels (atheroembolic strokes).In 30% of the cases,the underlying cause of the stroke is unknown (cryptogenic strokes).Strokes are classified as ischemic and hemorrhagic.Hemorrhagic strokes can be further categorized as subarachnoid hemorrhages and intracerebral hemorrhages.
