A Venous Duplex Study is also known as a LEV (lower extremity venous) or UEV (upper extremity venous) study. This test may be ordered if there is leg pain, swelling or a history of blood clot.
This non-invasive test is performed by an ultrasound technologist who uses a hand-held transducer to emit sound wave to create pictures. The pictures will show the walls of the veins, blood flow through the veins and any clot formation in the veins. This will pinpoint the level and severity of blood clot, if any.
1. Allow 45 minutes for one arm or leg and 1 1/2 hour for both extremities.
2. Wear two-piece clothing.
3. Your physician will be notified of the results.
