Lower Extremity Venous Ultrasound

Lower extremity venous ultrasound is a safe and painless way of visualizing the veins of the legs. It can detect the presence of deep vein thrombosis (DVT) and/or venous insufficiency (venous reflux disease). It uses a small hand-held device called a transducer to transmit and receive sound waves. Special equipment changes the sound waves into images that are seen on a monitor. This is the same technology used to image babies in utero (sonogram). During the study, the technologist may ask you to tighten your abdominal muscles while certain images are recorded. This is to assess for leakage in the valves that typically prevent back flow of blood into the legs.  

A lower extremity venous imaging needs no special patient preparation.  Plan on 30 to 90 minutes for the exam.
