Arterial duplex examination uses high frequency sound waves(ultrasound) that evaluates the flow of blood through the arteries of the arms or legs.
Reason for procedure:
To investigate the cause of the following symptoms:
Claudication (pain, fatigue, cramping or tingling in the leg(s) and/or arms brought on by exercise that goes away when resting)
Numbness of the legs and/or feet at rest
Cold legs and/or feet
Loss of hair on leg and/or feet
Paleness or blueness of the legs and/or arms
Weak or absent pulse in the leg or arm
Sores, injury, or infection of the feet and legs that heal slowly
Preparation:
None
What is done during the procedure?
A brief history will be obtained. You may be asked to change into a hospital gown. You will be asked to lie on a table. Gel will be placed on the skin of your arm or leg, over the arteries being tested. You may hear noises during the exam. This is the blood flowing through the arteries.
How long will it take?
The length of the test varies, depending on your particular situation. However, in most cases, it will take between 15-30 minutes.
Will it hurt?
When the blood pressure cuffs are inflated you will feel pressure. The sonographer works quickly to obtain the pressures to reduce the amount of discomfort.
