The technician shows your doctor the images from your exam. If there isn't any stenosis in your carotid arteries, your test results are normal. If your carotid ultrasound exam reveals some stenosis in your arteries, your doctor may recommend taking some preventive measures to avoid a stroke, such as reducing serum cholesterol with diet and statin medications and taking aspirin daily.
If one of your carotid arteries is narrowed by 70 percent or more, your doctor may recommend surgery to remove the blockage. However, your doctor may still recommend surgery even if your blockage is less severe. One procedure your doctor may recommend is a carotid endarterectomy. In this procedure, your doctor makes a small cut in the side of your neck and removes the blockage from your artery.
It's possible your doctor may not be able to tell if your arteries are narrowed from the ultrasound alone. If this is the case, your doctor may order more tests, such as a CT scan, angiography, or magnetic resonance angiography.
