Peripheral Venous Evaluation

The Venous Duplex Ultrasound is a noninvasive test which utilizes ultrasound imaging to evaluate the blood flow possible blockage and in the veins of the legs or arms. It is most often used to make sure that no blood clots are present in the veins.

Before the Test

There is no special preparation required for this test, but if you are having your legs tested, you may choose to bring along a loose fitting pair of shorts to wear during the test.

During the Test

For this test, you will be asked to lie quietly while the technologist moves a small instrument called a transducer over your legs or arms. Moderate pressure will be applied with the probe at various points. Your legs, abdomen or arms will be periodically compressed by the technologist's hand to cause flow in the veins being evaluated. You will be able to hear the flow of your blood during the Doppler portion of the test. The resulting images will be recorded and stored in your records. The test lasts approximately 30 minutes to an hour depending upon what needs to be evaluated.

After the Test

After the procedure you may leave without restrictions. There are no known risks from the use of ultrasound for medical diagnosis.
