Vein Ultrasound

A vein ultrasound is a noninvasive test that uses sound waves to look at blood flow through the veins. The test can help detect blood clots, identify venous reflux, examine varicose veins, and map veins before treatment. Duplex ultrasound is commonly used to evaluate both deep and superficial veins because it shows the structure of the vein and how blood is moving through it.

What Is a Vein Ultrasound?

Vein ultrasound may be recommended if you have leg swelling, aching, heaviness, tenderness, painful varicose veins, or symptoms that raise concern for a blood clot. A deep vein thrombosis leg ultrasound can help confirm or rule out DVT, while a reflux study can show whether damaged vein valves are allowing blood to flow backward.

Why Is A Vein Ultrasound Performed

Why Is a Vein Ultrasound Performed?

A vein ultrasound can provide information about blood flow and the condition of the veins beneath the skin. Your provider may recommend one when symptoms suggest a circulation problem or when more information is needed before treatment.

The test can be used to evaluate:

  • Varicose veins and venous reflux
  • Leg swelling, aching, heaviness, or tenderness
  • Deep vein thrombosis and other blood clots
  • Painful or inflamed veins
  • Vein anatomy before a procedure
  • Blood flow after certain vein treatments


Duplex ultrasound is the recommended diagnostic test for evaluating venous reflux in chronic venous disease.

Vein ultrasound allows your doctor to see inside your body. Your doctor will use ultrasound to see if the vein is open, which direction the blood is flowing, and if there is any vein issue causing your symptoms.

Deep Vein Thrombosis Leg Ultrasound

When DVT is suspected, duplex ultrasound is commonly used to look for a blood clot in the deeper veins of the leg. During the study, the veins are examined for blood flow and compressibility. A vein containing an acute clot may not compress normally.

Symptoms that can lead to a DVT ultrasound include sudden swelling in one leg, calf or thigh pain, warmth, tenderness, or changes in skin color.

How Is a Vein Ultrasound Performed?

During the test, gel is placed on the skin, and a handheld device called a transducer is moved over the area being examined. Sound waves are used to create images of the veins and blood flow on a monitor.

A vein ultrasound does not involve radiation, needles, or an incision. Most vascular ultrasound exams require little preparation and are generally painless.

Depending on the type of study, you may be asked to lie down, sit, or stand while different veins are examined. Reflux studies are often performed while standing when possible because this can provide a better assessment of how the vein valves function.

How Does a Vein Ultrasound Help Diagnose Vein Problems?

Ultrasound Vein Finder vs. Diagnostic Vein Ultrasound

An ultrasound vein finder is generally used to help locate a vein for an IV, injection, or blood draw.

A diagnostic vein ultrasound serves a different purpose. Rather than simply locating a vein, a duplex study evaluates blood flow, valve function, blockages, and possible blood clots.

If you have any symptoms such as swelling, pain, varicose veins, and others related to your circulation, a diagnostic vein ultrasound will provide all required data on your problem.
