What is the purpose of venous duplex ultrasound?

What is the purpose of venous duplex ultrasound?

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 is a duplex scan of extremity veins?

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 an ultrasound of the lower extremities?

A lower extremity ultrasound is a diagnostic imaging test used to evaluate the blood flow through the legs’ major veins. A Doppler ultrasound will measure your blood flow and blood pressure by bouncing high-frequency sound waves off the red blood cells circulating in the legs.

How is a duplex ultrasound done?

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. The B-mode transducer (like a microphone) obtains an image of the vessel being studied.

What happens during a duplex scan?

A duplex scan means that the provider uses 2 transducers. The second one (Doppler) lets your provider hear the sound waves the transducer sends out. He or she can hear how fast blood is flowing through a blood vessel and in which direction it is flowing.

What will ultrasound of legs show?

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.

Can ultrasound detect blood clot in leg?

Ultrasound scanning gives a clear picture of soft tissues that do not show up well on x-ray images. 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 a lower limb venous duplex?

Venous duplex of extremities is a non-invasive, ultrasound (sound waves) test to determine if there is any narrowing or blockage in the veins of a patient’s upper or lower extremities. Your lower extremities (legs and ankles) could be experiencing symptoms, such as swelling or pain in legs or excessive varicose veins.

What is a bilateral venous duplex?

Venous duplex scan is a painless exam that uses high-frequency sound waves (ultrasound) to capture images of internal views of veins that return blood to the heart. During an upper extremity venous duplex scan, the veins in your neck, shoulders, arms and wrists are viewed.

What is a non vascular ultrasound?

Musculoskeletal or Extremity Non-Vascular Ultrasound is an exam that obtains images of the area of interest (examples could be arm, leg, knee, shoulder, foot).

What is the CPT code for a venous Doppler ultrasound?

Venous Doppler ultrasound procedures are billed using either CPT code 93970 or 93971, according to Radiology Today magazine.
