The quality of intravenous digital subtraction angiograms was sufficient for diagnostic evaluation in 90%. The accuracy of the method was 90% for the internal carotid artery. 40% of the internal carotid arteries showed stenoses, whereas the common and external carotid arteries were not narrowed in 90%. On behalf of these data the authors consider that i.v. DSA of the carotid vessels is a suitable screening method for carotid arterial occlusive disease.
