The anatomic, clinical, and radiologic findings of aberrant subclavian arteries (ASAs) are well known. Acquired diseases such as aneurysms, dissections, or stenosis can complicate these anomalies. We propose that these complications are a result of atherosclerosis caused by abnormal turbulence around the ASA. Comparisons of computed tomographic and angiographic measurements of subclavian arteries in adults with and without arch anomalies and angiographic measurements of ASAs in children show that ASAs dilate in older patients. We describe six patients with acquired diseases of ASAs or the aorta adjacent to the ASA. Aneurysms, aortic dissections, and stenosis were each found in two patients. Problems in the radiologic diagnosis and clinical management of these diseases are emphasized. Radiologists should be cognizant of the significance of ASAs in patients with aortic aneurysms and dissections.
