Bilateral intracranial arteriograms of 123 right-handed patients and 38 left-handed patients were evaluated for: (1) the angulation of the branches of the right and left middle cerebral arteries as they leave the Sylvian fissure, (2) the position of the posterior saggital sinus with respect to the anatomic saggital midline, and (3) the dominant right-sided and left-sided superficial cortical venous drainage (Labbé, Trolard, and Sylvian). Arteriographic evaluations of these points may prove useful in assessing cerebral dominance.
