Duplex Ultrasound

ALSO CALLED: Doppler Test, Vascular Lab Test, Duplex Exam, Duplex Scan, Ultrasound, or Ultrasound Exam

What is it?

Duplex ultrasound is a non-invasive evaluation of blood flow through your arteries and veins. Many arteries and the veins can be studied by ultrasound, including the carotid, arm and leg arteries as well as the abdominal aorta. Veins are also tested to help detect a clot or reflux. This test provides information to help your vascular surgeon make a sound diagnosis and outline a treatment plan. Accuracy is critical, so ultrasound testing should ALWAYS be performed by a credentialed sonographer in an accredited vascular laboratory. Ultrasound examinations are painless and easy for the patient.

What to expect during the test?

The vascular laboratory will contain a bed and just two or three pieces of equipment. The examination can be done in comfortable clothing; disposable shorts or gowns may be provided. It usually takes about 30 minutes.

Are there any risks or side effects?

There are typically no side effects or complications associated with duplex ultrasound examinations.

What should I do to prepare?

There is little preparation required for duplex ultrasound. Occasionally, patients may need to fast before an abdominal exam. 

What can I expect after the test?

There should be no side effects following a duplex ultrasound. The results of your study will be made available to your doctor, and any necessary follow up visits or treatment will be scheduled accordingly.
