Stroke Screenings and Carotid Artery Stenosis

The carotid arteries in your neck provide the main supply of blood to the brain. A buildup of plaque in these arteries, narrows the artery, or carotid artery stenosis (CAS), can increase possibility of a stroke.

If you have an increased risk for a stroke, carotid artery screening is a an easy noninvasive ultrasound procedure to detect abnormalities in the carotid arteries before other symptoms are present. However, carotid artery stenosis screening is only recommended for those with two or more common risk factors to a stroke. As a rare disease, it can be difficult to determine whether or not one is a good candidate for screening. Here are the signs that this procedure is right for you.

Symptoms & Risk Factors

Having mild symptoms of cardiac disease, such as high blood pressure, may not be enough to qualify you for carotid screening. According to the American Heart Association, the American Stroke Association and other healthcare organizations, carotid screening is recommended for those with two or more of the following risk factors:
● Smoking
● High blood pressure
● High cholesterol
● A first-degree relative with atherosclerosis that developed before age 60
● A family history of ischemic stroke

History of Artery Disease

For some patients, the existence of other common cardiac diseases may also be a reason to consider screening. A diagnosis or a family history of the following artery diseases may increase one’s risk of CAS:
● Peripheral Artery Disease (PAD)
● Coronary Artery Disease
● Aortic Aneurysm

Talking to Your Doctor About CAS

Carotid artery stenosis occurs in roughly 0.5-1% of the general population. Therefore, screening should only be taken into consideration if the previous requirements or symptoms of CAS are present. If you are concerned about your risk of a stroke, ask your doctor if CAS screening is right for you.

The Vascular Lab at Muskegon Surgical Associates offers select free screenings throughout the year. For more information on these dates, or to schedule your carotid or vascular screening, contact our office.
