We Compared Clinical and Arteriographic Features in 27 White and 24 Black Patients with Symptomatic Posterior Circulation Occlusive Disease. the Degree of Arterial Stenosis Was Measured Independently by Two Examiners at 12 Sites within the Vertebrobasilar Territory. Racial Comparisons Were Made based Upon the Distribution of Extra- and Intracranial Occlusive Lesions and Symptomatic Sites of the Lesions. White Patients Had Significantly More Angina Pectoris, More Lesions of the Origin of the Left Vertebral Artery and More High-Grade Lesions of the Extracranial Vertebral Arteries. Black Patients Had Significantly Higher Mean Diastolic Blood Pressure, More Diabetes Mellitus, More Lesions of the Distal Basilar Artery, More High-Grade Lesions of Intracranial Branch Vessels and More Symptomatic Intracranial Branch Disease. Race Was Found to Be the Only Factor Increasing the Risk of Intracranial Posterior Circulation Occlusive Disease. Knowledge of the Contribution of Race to the Distribution of Posterior Circulation Lesions Will Help Guide Evaluation and Treatment Strategies for Patients with Vertebrobasilar Occlusive Disease. © 1985 American Heart Association, Inc.
