Venous Duplex Scan

Venous duplex scans use high-frequency sound waves to visualize the vessels and evaluate blood flow throughout the veins in the legs. Using a specialized Doppler technique, we can also measure the movement of blood within the vessels. This provides detailed pictures of these blood vessels to help physicians determine the extent and cause of restricted blood flow.

Common Questions

  • Why would my physician recommend Venous Duplex Scan?

    Your physician may recommend a venous duplex scan to search for blood clots, especially in the veins of the leg. It may also be performed to determine the cause of leg swelling, for pre-surgical vein mapping, or to examine a blood vessel graft used for dialysis.

  • What do I need to do before my procedure?

    You will be given detailed instructions by our staff before your procedure. Be sure to bring your insurance card, photo ID, list of current medications (dose and frequency) and any diagnostic testing results.

  • What should I expect during a Venous Duplex Scan?

    You will lay face-up on a moveable exam table and you may be turned to either side. Warm gel is placed over the area to be tested (typically from the groin / upper thigh to the lower calf) and a probe is gently passed back and forth on your skin over the area to create and pick up sound waves, which are converted into an image on a screen. During the exam, you will hear the ultrasound machine reproduce your pulse as detected through the Doppler component of the exam.

  • What should I expect after a Venous Duplex Scan?

    When the imaging is complete, the clear gel will be wiped off your skin. After the procedure, you may resume your normal activities immediately.

Because of a chronic problem I had with edema in my legs over the years, this was my fourth Doppler. I would like to especially highlight what a positive experience this particular time was. My technician was exceptional. From the moment I met her, she made it clear that my comfort and my safety were the foremost concern in the process. She was able to eliminate most of the concerns created by my former experiences. From the front desk to the final procedure I was impressed and felt good about it. My kudos to you and your leadership as well.
