When your doctor examines you, he or she may discover a warning sign of carotid artery disease through a very simple method: putting a stethoscope on your neck and listening. This is a diagnostic procedure that can sometimes detect a whooshing sound called a bruit. This sound indicates uneven blood flow through the carotid arteries, which can be caused by narrowing of those arteries. The carotid arteries are critical for life and good health because they carry blood to the brain. A bruit can be a starting point for a diagnosis but must be supplemented by other more accurate and specific tests.
