Department of Radiology, University of South Alabama, Mobile, Alabama A patient with a right-sided aortic arch giving origin to an aberrant left subclavian artery with circumferential ostial stenosis is reported. This asymptomatic anomaly was discov ered serendipitously during cerebral arteriography for subarachnoid hemorrhage. The embryologic origin of this anatomic variant is discussed, as are some practical implica tions relating to the angiographic technique of selective catheterization of branches of the aortic arch.
