Redman concluded that "arteriography should be performed on all of these patients to confirm the presence of an aneurysm and also to determine its extent." It is our conviction that abdominal aortic aneurysms can nearly always be identified clinically and that aortography is rarely indicated to define their presence or extent.

A tortuous atherosclerotic aorta usually can be identified by physical examination alone. Similarly, careful examination can prevent one from being misled by extraneous vascular calcifications in other abdominal vessels. In a series
