The availability of the less invasive techniques such as CT, MRI, and digital angiography require reexamination of the indications for conventional screen-film aortography. Because of poor image quality, IV digital subtraction angiography should be limited to congenital aortic disease and follow-up cases. Intraarterial digital angiography can be used as a supplement to or as a replacement for conventional aortography in most cases. Care should be used in substituting intraarterial digital angiography for conventional studies in aortic dissection and aortic rupture; continuing problems with digital subtraction artifacts may introduce error in cases with subtle abnormalities. In aortic aneurysm, CT is usually sufficient for diagnosis and surgical planning with angiography used for inconclusive examinations or more accurate determination of branch involvement. CT is the primary diagnostic examination in suspected chronic or subacute dissection and is the method of choice in sequential studies of patients following medical or surgical therapy for dissection. In acute aortic dissection, either angiography or CT may be used and are equally diagnostic. Angiography is most helpful in aortic dissection with suspected brachiocephalic vessel involvement, coexistant coronary artery disease, or in cases of indeterminate CT. In blunt chest trauma, aortography remains the examination of choice in the diagnosis of aortic transection. CT may play a role in excluding aortic damage in stable patients with a low clinical suspicion of aortic transection.
