We assessed the utility of a Doppler ultrasonographic examination of the
vertebral artery, limited to the intertransverse segment, in diagnosis of
disease at any level of vertebrobasilar circulation. The vertebral artery
was identified in all the patients, with a successful evaluation of the
presence of disease in 112 of 116 (96.5%) vertebral arteries. All of the
occlusions and subclavian steal syndromes were diagnosed. All of the
vertebral arteries with abnormal Doppler findings had a pathologic
angiographic study. In conclusion, Doppler ultrasonography of the
intertransverse segment of the vertebral artery is useful owing to its
applicability and accuracy.
