Non-Invasive Carotid Evaluation: Carotid Artery Duplex

What is Carotid artery disease?

Carotid artery disease is one of the most common causes of stroke. Identifying potentially treatable causes of stroke, such as carotid artery disease, is a key step in stroke prevention.

What is a carotid artery duplex examination?

The carotid duplex is a type of noninvasive vascular ultrasound study done to assess for blockage or narrowing of the carotid arteries of the neck. The examination includes the assessment of the carotid arteries and its branches, vertebral arteries, and subclavian arteries on both sides.

What are the indications or symptoms for a Carotid Duplex?

  • Carotid Bruit - a sound or murmur heard in the neck when your doctor listens with a stethoscope
  • History of stroke
  • TIA (Transient Ischemic Attack) - symptoms that resolve within 24 hours, such as aphasia (the inability to speak), Dysphasia (impairment of speech), Parethesia (tingling and/or numbness on one side of the body)
  • Amaurosis fugax – transient monocular blindness in one eye
  • Known carotid stenosis
  • Follow up of carotid endartectomy
  • Symptoms of lightheadedness or dizziness
  • Syncope or “drop” attacks (vertebral basilar insufficiency)

What can I expect during the exam?

The examination takes approximately 30 minutes.  It is performed in a darkened room lying on an exam table.  A technologist will perform the exam by taking images of the arteries using the ultrasound equipment.  A transducer is placed on the neck with a small amount of water soluble ultrasound gel. 

Patient Instructions

  • Wear a shirt or blouse with a low and loose fitting collar (i.e. no turtlenecks).
  • No other special preparation is needed for this study.
