What is the purpose of arterial testing?

Arterial testing is used to evaluate both the aorta and peripheral arteries in the arms, hands, legs and feet. The ultrasound evaluation of the aorta is the main screening test to detect abdominal aortic aneurysms (AAA) and also is the main test to follow these aneurysms after detection. Vascular laboratory arterial testing also is used for the evaluation of atherosclerosis and other vascular diseases in the extremities, which may produce pain in the extremity or threaten the limb. Arterial testing utilizes blood pressure measurements in conjunction with duplex ultrasound to provide physicians with a complete picture of upper and lower extremity circulation.
