Ultrasound – Carotid Artery Screening

Carotid artery disease occurs when plaque, a build-up of fat, cholesterol and other substances, collects and forms along the walls of the carotid arteries. This buildup of plaque and the injury it causes is called atherosclerosis. Over time, the walls of affected arteries thicken and become stiff and the blood vessel may also become narrowed, a condition called stenosis, limiting … Read More
