Cerebral Atherosclerosis in Japanese. 3. Predilection Site of Atherosclerotic Lesions
Four hundred twenty-three intracranial cerebral arteries (males and females) were obtained from the medicolegal autopsy cases. Special attention was given to the three sites and the circumferential distribution of lesions in order to investigate the effects of hydrodynamics on the development of cerebral atherosclerosis. The severest lesions were primarily found at the inner curvature at the terminal portion of the internal carotid artery, the medial portion at the origin of the anterior cerebral artery, and the posterior portion at the origin of the posterior cerebral artery. The present results obviously demonstrated the relationship between the predilection sites of atherosclerotic lesions and the shape of the cerebral arterial tree.
