Peripheral Doppler

Ultrasound is used to record blood velocities through the main arteries of the leg. Velocities can indicate the presence of arterial stenosis.

Peripheral arterial disease (PAD), also called peripheral vascular disease (PVD), is inadequate blood circulation in the legs, most likely due to plaque buildup in the arteries. Risk factors include hypertension, diabetes, smoking, and obesity. Pain or cramping while walking, called claudication, is a common symptom. More advanced cases of peripheral arterial disease may include signs such as absent pulses in the feet, abnormally-colored skin, shiny skin on the legs and feet, cold legs and feet, thick toenails, and open sores. Ultrasound is used for peripheral arterial disease screening.
