Carotid Artery Disease

Dr. Hart given medical report

The carotid arteries are the blood vessels located on both sides of your neck that carry blood to the head and brain. Carotid artery disease is the buildup of plaque in these arteries, causing a narrowing, or blockage, of the artery. Carotid artery disease can lead to a stroke or transient ischemic attacks (also called TIAs or mini-strokes).

Most often, carotid artery disease is silent and unsuspected. Occasionally, the narrowed arteries produce a noise that can be heard with a stethoscope over the neck. If your healthcare provider suspects that you have carotid artery disease, he or she will ask you specific questions, examine you, and may order a diagnostic test such as carotid duplex imaging, computed axial tomography (CAT scan), magnetic resonance angiography (MRA), or an angiogram.

The treatment for carotid artery disease depends on the severity, the symptoms you have experienced, and your overall state of health. Mild or moderate stenosis may be treated with medication and by reducing as many risk factors as possible to slow the growth of the stenosis. Your healthcare provider will discuss the importance of reducing your risk factors and regular medical follow-up. More severe carotid artery stenosis may sometimes be treated with an operation know as carotid endarterectomy. This is a surgical procedure in which the plaque and inner lining of the artery is removed. An incision is made, the carotid arteries are located; clamps are placed above and below the surgical site; the carotid artery is opened; and the plaque is carefully removed. The artery is then closed with a patch of a vein or an artificial/synthetic material; sutures or staples are applied to the skin and the area is covered with a dressing. In certain instances, it may be possible to treat carotid stenosis through catheters inserted in the groin with stents placed in the carotid artery to improve the flow through the region. This approach is very new and the devices have only recently been approved for use by the FDA. As the technology develops, more and more patients will be candidates for this procedure.

The best treatment for carotid artery disease depends on a number of factors, including the size and location of the stenosis, whether or not it is causing symptoms, and the age and general health of the patient. You should discuss all of these factors and any other questions you have with your primary care physician.
