In China, when it comes to any disease, doctors tend to start with internal medicine to see if conservative medical treatment can work, and only as a last resort do they go for surgery. This is the case for many patients with carotid stenosis, and there are few patients who hope too much for conservative treatment and do not seek medical attention in time. Is conservative treatment of carotid stenosis really safe? How to choose the right treatment for you? When patients experience dizziness, nausea, numbness in the limbs, weakness, speech disorders, etc., if medication is taken and the effect is not satisfactory, it is recommended to go to a hospital for examination and then take surgical treatment. For people whose carotid artery has been stenosed before, or who have cerebral infarction but do not have any symptoms, these people are often at high risk, and they can first be treated by medication to stop intimal hyperplasia, stabilize the plaque and control the condition, and then be observed regularly. Cerebral infarction appears, the plaque is dislodged, and the lumen is severely narrowed. At this time, if surgical treatment is not yet taken, the cerebral infarction may recur. For the time when the plaque is more stable and the stenosis is not very serious, it can be prevented by conservative treatment. Surgical procedures, one is traditional stent intervention, which can make the narrowed lumen smooth, with a high chance of secondary stenosis. Another is carotid endarterectomy, which was once widely used in Europe and the United States. The main purpose of the procedure is to remove the plaque with the advantage of a microscope.
