Venous Doppler

Venous Doppler Examination is a non-invasive exam using Ultrasound and Doppler to create a two-dimensional picture of your veins to evaluate the venous blood flow in the deep venous system of your upper or lower extremities. This test is helpful in diagnosing a blood clot or a DVT (Deep Vein Thrombosis.)

Q: What can I expect during a Venous Doppler?

A: You will be asked to remove clothing from the waist up or waist down depending on whether you have scheduled an upper or lower extremity Venous Doppler. You will be given a gown and sheet to wear during the examination. The technologist will perform the procedure with you lying on your back. A clear gel will be applied to your arms or legs. When the transducer or Ultrasound probe is placed over the arm or leg an image will appear on the monitor. When evaluating the blood flow you will hear a noise emitted from the Ultrasound unit as the technologist manually squeezes your arm or leg. The technologist will use the transducer to compress the veins. You may experience a slight discomfort during this maneuver. The examination will take approximately 45 minutes.

Q: What are the risks involved in a Venous Doppler?

A:  Since the examination is non-invasive, there are no dyes or x-rays used, there is no pain or risk involved.

Q: Is there preparation involved?

A: You may eat, drink and take daily medications as usual.
