Carotid Duplex Ultrasound
A Carotid Ultrasound is a simple ultrasound scan used to detect and follow the progression of cerebrovascular disease ("CVD", or plaque build up in the carotid arteries). The carotid arteries carry oxygenated blood from the aorta, along both sides of the neck, and are the main supply of blood to the face and brain. Detecting and treating significant plaque build up is an important stroke prevention measure.
During the scan you will recline comfortably on an exam table, your neck will be draped, and your arteries will be imaged by a specially trained technologist using a small ultrasound probe. The test is not uncomfortable and the scan itself takes approximately 10 to 15 minutes on each side of your neck. The test is interpreted by a cardiovascular specialist.
Some common indications for this test include:
- Confusion, fainting or non-responsiveness
- Disturbances of vision or speach
- Numbness, weakness or paralysis; facial drooping
- History of previous stroke (CVA) or transient ischemic attack (TIA)
- Arterial disease in other parts of the body, such as coronary artery disease (CAD) or peripheral arterial disease (PAD)
- A "bruit" or slightly louder blood flow sound over the carotid artery when the doctor listens with a stethoscope
There is no special preparation for the test. Please bring your insurance card and co-pay (if any) to your appointment.
