Whether or not it is important to have a strong echogenic plaque in the carotid artery should be determined on a case-by-case basis. If the size of the plaque is small and the patient does not have the corresponding symptoms, it is usually sufficient to review the plaque on time; if the plaque is large or the patient develops the corresponding symptoms of cerebral insufficiency of blood supply, timely medical treatment should be sought. Carotid ultrasonography shows plaque, usually suggests the existence of atherosclerosis. Atherosclerotic plaque is categorized into hypoechoic plaque and strong echogenic plaque. Hypoechoic plaque is relatively less stable and prone to plaque detachment and activity, while strong echogenic plaque is relatively more stable and less likely to be detached. If the plaque volume is small and the patient does not have corresponding symptoms, it is usually sufficient to review the examination on time and observe the patient’s symptoms. If the carotid ultrasound examination shows hypoechoic plaque, large volume of strong echo plaque, or incomplete plaque outer membrane, it belongs to unstable plaque, which may lead to plaque rupture, bleeding, dislodgement, etc., causing cerebral artery embolism, which can cause cerebral infarction in severe cases. It is recommended that the patient should seek medical treatment in time and under the guidance of the doctor. Carotid artery suggests strong echoes, should consult the doctor in time, the doctor according to the individual situation to determine whether it is important, if necessary, for treatment.
