Abstract
Since many aortic arch lesions are amenable to surgical treatment, aortography has assumed greater importance. Retrograde aortography should not be used if dissecting hematoma (aneurysm) is a possibility. An area of arteriosclerotic stenosis of one of the vessels arising from the aortic arch is not necessarily an indication for surgery. “Pseudocoarctation” only confirms the presence of severe atherosclerosis but is occasionally mistaken for a tumor or an aneurysm.
