Carotid disease without stroke or TIA (Transient Ischemic Attack) is usually completely without symptoms (asymptomatic). It may be discovered by your doctor hearing whooshing noises (sometimes called a “bruit”) over the arteries in your neck, but otherwise may produce no other symptoms you would notice. Carotid disease is usually discovered and confirmed by a test called duplex ultrasound. Other tests may include CT scans or MRI. Screening ultrasounds discovers some carotid disease.  Find out if a screening ultrasound makes sense for you.
