Carotid artery blockage is not clinically self-evacuating. The progress of the disease can be slowed down by treating the underlying disease, medication and surgery. 1. Treatment of underlying diseases: patients with carotid artery blockage need to quit smoking and drinking, and at the same time, reduce the intake of sugary and fatty foods, and patients with high blood pressure need to limit the intake of salt and eat more vegetables. 2. Medication: Patients with mild carotid artery blockage need to use statin drugs such as atorvastatin calcium or Rosuvastatin calcium tablets under the guidance of a doctor. Patients with high risk of stroke can add antiplatelet drugs, such as aspirin or clopidogrel, to prevent cerebral infarction under the guidance of a doctor. 3. Surgical treatment: For patients with severe carotid artery blockage, carotid endarterectomy or interventional endovascular treatment can be performed under the guidance of doctors after a complete vascular assessment. Patients with carotid artery blockage need to go to the hospital in a timely manner, and under the guidance of the doctor for symptomatic treatment.
