title: Pitfalls of digital angiography in the diagnosis of right aortic arch.
abstract: The authors describe the difficulties using intravenous digital subtraction angiography, in diagnosing on a left anterior oblique view a right aortic arch with aberrant left subclavian artery and left descending aorta. The proximal topography of the left common carotid artery ostium is a useful sign in the diagnosis of this kind of abnormality.
