This test helps to determine how the blood is flowing through your veins. Venous duplex scans can show blood clots in leg veins and evaluate for abnormal veins causing varicose veins.

What does a venous ultrasound show?
Venous ultrasound helps to detect blood clots in the veins of the legs before they become dislodged and pass to the lungs. It can also show the movement of blood within blood vessels.
What is venous duplex test?
A Venous Duplex Scan is a type of dedicated ultrasound to look at the venous system. This procedure is performed to evaluate symptoms including leg pain or swelling, leg heaviness, excessive varicose veins, leg discoloration, shortness of breath, or suspected blood clots in your legs and/or lungs.
What is a duplex scan for?
A duplex ultrasound is a test to see how blood moves through your arteries and veins.
What can ultrasound of leg detect?
A Doppler ultrasound may help diagnose many conditions, including: Blood clots. Poorly functioning valves in your leg veins, which can cause blood or other fluids to pool in your legs (venous insufficiency) Heart valve defects and congenital heart disease.
What is the difference between venous Doppler and venous duplex?
A Doppler ultrasound may also be performed to capture images of the movement of blood through your veins. This test helps to determine how the blood is flowing through your veins. Venous duplex scans can show blood clots in leg veins and evaluate for abnormal veins causing varicose veins.
How do you know if you have poor circulation in your legs?
Symptoms of Poor Blood Circulation
- Swollen veins and arteries (varicose or “spider” veins)
- Heaviness in legs and feet.
- Skin discoloration.
- Swollen legs and feet.
- Split, weeping skin.
- Ulcers.
- Pelvic pain or discomfort.
- Restless legs and feet.
Is duplex the same as Doppler?
Doppler is a kind of ultrasonography which is a medical non-invasive study of blood vessels and heart, includes high-frequency waves with ultrasound. On the other hand, Duplex is a type of ultrasonography that is also a medical non-invasive study combining Doppler ultrasonography and traditional ultrasonography.
What is a duplex scan of legs?
Ultrasound is a procedure that uses sound waves to “see” inside your body. An arterial duplex ultrasound uses sound waves to create a color map of the arteries in your legs to identify: Narrowing of your vessels that may be causing leg pain when walking. Resting leg pain.
Is a duplex scan an ultrasound?
Duplex ultrasound involves using high frequency sound waves to look at the speed of blood flow, and structure of the leg veins. The term “duplex” refers to the fact that two modes of ultrasound are used, Doppler and B-mode.
What causes venous insufficiency?
What causes chronic venous insufficiency?
- High blood pressure in the leg veins over time, due to sitting or standing for long periods.
- Lack of exercise.
- Smoking.
- A blood clot in a deep vein, often in the calf or thigh (deep vein thrombosis)
How long does a venous duplex ultrasound take?
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.
What kind of ultrasound will rule out a DVT?
Complete duplex ultrasound (CDUS) is the preferred venous ultrasound test for the diagnosis of acute DVT.
What are the warning signs of deep vein thrombosis?
DVT signs and symptoms can include:
- Swelling in the affected leg. Rarely, there’s swelling in both legs.
- Pain in your leg. The pain often starts in your calf and can feel like cramping or soreness.
- Red or discolored skin on the leg.
- A feeling of warmth in the affected leg.
What do red spots on an ultrasound mean?
By definition, flow towards the transducer is depicted in red while flow away from the transducer is shown in blue. Different shades of red and blue are used to display velocity. Lighter shades of color are assigned to higher velocities.
What do you wear for leg ultrasound?
You may want to wear shorts for this exam, and your feet should be bare during the test. If you are not wearing shorts, you may have to change into a hospital gown. If you have a history of surgery on your legs or arms (i.e., stents, grafts), you should inform the technologist.
