Arterial Study of Limb (Single)

Your doctor may suggest a Doppler ultrasound scan if you show signs of decreased blood flow in the arteries or veins of your legs, arms, or neck. A reduced amount of blood flow may be due to a blockage in the artery, a blood clot inside a blood vessel, or an injury to a blood vessel.

Your doctor may order a Doppler ultrasound exam if you show signs of:

*deep vein thrombosis (DVT), a condition that occurs when a blood clot forms in a vein deep inside your body (usually in the leg or hip regions),
*superficial thrombophlebitis, an inflammation of the veins due to a blood clot in a vein just below the skin’s surface
*arteriosclerosis, a narrowing and hardening of the arteries that supply blood to the legs and feet
*thromboangiitis obliterans, a rare disease in which the blood vessels of the hands and feet become inflamed and swollen
*vascular tumors in your arms or legs
A Doppler ultrasound can help determine the blood pressure within your arteries. It can also show how much blood is currently flowing through your arteries and veins.
