What is a duplex venous lower extremity?
A Venous Duplex Scan is a type of dedicated ultrasound to look at the venous system. The ultrasound uses sound waves to see the veins and evaluate blood flow within them. This exam is commonly used for veins in the legs and abdomen, but it can be applied to any other veins such as the neck or arms.
What is a venous duplex of bilateral lower extremities?

How is a duplex ultrasound performed?
A wand, called a transducer, is moved over the area being tested. This wand sends out the sound waves. A computer measures how the sound waves reflect back, and changes the sound waves into pictures. The Doppler creates a “swishing” sound, which is the sound of your blood moving through the arteries and veins.
What do you wear for a leg ultrasound?
You will need to wear blood pressure cuffs on your arms and legs for this test. For most ultrasound exams, you will be asked to lay on the exam table. A pair of shorts may be provided as the ultrasound gel may get on your clothing.
