What is an Arterial Ultrasound?
An arterial ultrasound is a non-invasive test that examines the arteries carrying blood from the heart to the extremities. It can detect any buildup of plaque in the arteries, which can cause narrowings or blockages that restrict blood flow, a condition known as peripheral arterial disease. Symptoms of peripheral arterial disease include reproducible cramping pain in the legs or buttocks after walking a certain distance, as well as numbness in the feet which is most severe at night when lying down. The test can help diagnose and monitor this condition.
Is there a difference between a Lower Arterial Ultrasound and an Upper Arterial Ultrasound?
A lower arterial ultrasound examines the blood flow in the arteries of the legs and feet, while an upper arterial ultrasound evaluates the arteries in the arms and neck. The procedures are similar, but the specific areas being examined are different, as the blood flow patterns and potential issues can vary between the upper and lower extremities.
How do you prepare for an Arterial Ultrasound?
While no specific preparation is required for an arterial ultrasound, you may be asked to change into a gown to expose the area being examined. If your lower extremities are being examined, you will need to remove your shoes, socks, and pants. The procedure itself is non-invasive and painless.
