ABSTRACT
Background: Anemic hypoxia is characterized by reduced hemoglobin content with normal arterial oxygen tension and saturation. Paients with severe atherosclerotic narrowing in brain lack the reserve capacity to preserve tissue oxygenation in reduced hemoglobin level. We evaluate the effect of anemia in severe atherosclerotic narrowing in cerebral vasculature. Case Report: We present five patients with severe atherosclerotic lesion who developed transient or permanent neurological deficits occurred during a severe anemia and recovered or improved after transfusion. Conclusions: Iron deficiency should be considered in the differential diagnosis of vascular events and treated as a preventive measure in reducing the risk of stroke in the severe atherosclerotic narrowing in cerebral vasculature.
