The treatment of carotid atherosclerosis includes medication and surgery, the former such as aspirin, atorvastatin and other drugs, the latter commonly used carotid endarterectomy and stent implantation. Mild stenosis (less than 50%) can be considered for drug therapy, which mainly includes antiplatelet aggregation therapy and lipid-lowering therapy. Antiplatelet drugs mainly include aspirin and clopidogrel. The main effect of antivascular drugs is to fight platelet aggregation and reduce the probability of thrombosis. Lipid-lowering therapy drugs mainly include statins such as atorvastatin and resuvastatin. They can lower the level of LDL in the blood and are antioxidant to stop plaque progression. Severe stenosis can be treated surgically (greater than 70%) with carotid endarterectomy and stenting. Patients with carotid artery stenosis between 50% and 70% may be considered for surgery if they have significant symptoms of cerebral artery ischemia. If there are no obvious symptoms, oral medication can be used. If carotid atherosclerosis is detected, patients should consult a doctor in time to choose the appropriate treatment.
