The Smaller Intracerebral Vessels

ANNA L. ELLINGTON M.D.¹

¹ University of Minnesota Medical School, Minneapolis, Minnesota

A pathological study of the smaller intracerebral arteries of 150 to 600µ was made in 336 cases, ranging in age from 1 day to 96 years. The changes involved the media and adventitia in contradistinction to the large cerebral vessels which showed predominantly intimal changes. The degree of change in the smaller intracerebral arteries was age related but not on a 1:1 basis. A comparison of the degree of change was also made with the large cerebral vessels of the circle of Willis, and although both were age related, they did not appear to be related to each other.

Key Words: cerebral arteriosclerosis • circle of Willis age and smaller intracerebral vessels
