Vein Duplex Ultrasound of the lower extremity

What is a Vein Duplex Ultrasound of the lower extremity?

A venous Doppler ultrasound is a diagnostic test used to check the circulation in the large veins in the legs (or sometimes the arms). This exam shows any blockage in the veins by a blood clot or “thrombus” formation. It can also tell us if you have veins in your legs that are “leaky” and can cause swelling.

What can I expect the day of my test?

You will be lying on the exam table on your back with your hands at your sides. The technologist will apply a warm gel to your legs and a transducer or a small microphone will be used to examine your veins. You will hear the sound of moving blood during the exam. Do not be alarmed; it is harmless. Your exam will take approximately 15 to 30 minutes.
