Doppler ultrasonography of an extremity

A normal result means the blood vessels show no signs of narrowing or closure, and the arteries have normal blood pressure.

Abnormal results may be due to:

• Blockage in an artery by a blood clot, piece of fat, or an air bubble
• Blood clot in an artery or vein
• Spastic arterial disease (arterial contractions brought on by cold or emotion)
• Venous occlusion (closing of vein)

Additional conditions under which this test may be performed include:

• Arteriosclerosis of the extremities
• Deep venous thrombosis
• Superficial thrombophlebitis
• Thromboangiitis obliterans
• Vascular tumors of the arms or legs
