• In a pilot study to evaluate the diagnostic potential of ultrasound scanning relative to peripheral arterial aneurysms, 34 selected patients were included. Normal femoral and popliteal artery size was determined by ultrasound scanning in young, healthy controls, confirmed in atherosclerotic individuals, and substantiated in patients with abdominal aortic aneurysms. Thirteen peripheral aneurysms were included in the study. Ultrasound scanning was found to be more accurate in peripheral aneurysmal evaluation than physical examination or arteriography, and was entirely acceptable to patients. The diagnostic potential of ultrasound scanning in peripheral aneurysms deserves continued and further investigation. It is apparent that it is an accurate, noninvasive, and painless method of gaining valuable information.
