We all probably know someone who's suffered a stroke and the dramatic changes to their lives as a result of that stroke. We at the vascular Institute of the Rockies are committed to the prevention of stroke with our diagnostic efforts and surgical treatment options.
Fortunately, the diagnosis of carotid artery narrowing can usually be done painlessly with an ultrasound. Our vascular lab performs these studies and is nationally certified. Carotid artery narrowing may occur without symptoms until you have a stroke. Your physician may hear an abnormal sound when they are listening to your neck with a stethoscope. This is called a bruit (brew-ee). If you have had an episode where you briefly lost vision in one eye, had weakness on one side of your body, had slurred speech or weren’t able to get your words out, your doctor will likely order an ultrasound. Your physician may also order an ultrasound if you have risk factors for stroke such as tobacco smoking, heart disease, hypertension, aneurysm, or prior vascular bypass.
Mild carotid narrowing without any symptoms can be followed by ultrasounds every 6 to 12 months. Controlling the risk factors for atherosclerosis and stroke can sometimes slow or stop the progression of atherosclerosis. This includes stopping smoking, regular exercise, control blood pressure, control diabetes, treat elevated cholesterol, and maintain a normal weight. Your physician will likely recommend an aspirin a day or another antiplatelet medication.
More severe narrowing, or patients with symptoms felt to be due to narrowing, will be evaluated for an operation called carotid endarterectomy. In this operation, an incision will be made on the side of the neck. The artery is opened and the plaque removed. The opening in the artery is then stitched closed. The operation takes about 2 hours and most patients go home the next day.
