Venous Duplex (Reflux/DVT)

Venous duplex is a non-invasive diagnostic test used to evaluate blood flow in the veins of the legs and arms. It is often requested to pinpoint the cause of pain or swelling in the extremities, or to diagnose a wide range of venous abnormalities and conditions, including venous reflux and deep vein thrombosis (DVT). Venous duplex is one of the many diagnostic tools used at Northwest Vascular & Vein.

 

How does it Work?

Duplex ultrasound combines two types of technology that uses sound waves to create pictures of your veins. Conventional ultrasound provides imaging of the structure of the vein, while Doppler ultrasound actually records blood movement through the vein. This test can be used to locate blood clots in the case of DVT or determine whether blood is pooling in a vein due to faulty valves.

A warm gel is applied to the skin and then a handheld device, known as a transducer, is run across the surface. Images of the vein appear on a screen and the technician performing the examination can take measurements and collect other data for the physician. A venous duplex examination usually takes 30 minutes or less to complete and patients may return to work and regular activities as soon as the examination is over.

Venous duplex is a non-invasive way to diagnose a host of venous disorders to that proper treatment can be recommended. To learn more about venous duplex or other diagnostic tools available to detect vascular conditions, contact Northwest Vascular & Vein.
