Carotid plaque is usually difficult to be completely eliminated after it occurs, and it needs to be improved by medication, stenting, carotid endarterectomy and other methods to improve the symptoms and play a therapeutic effect. Carotid plaque is a manifestation of carotid atherosclerosis, and its formation is related to hypertension, hyperlipidemia, hyperhomocysteinemia, age, genetics and other factors. When carotid plaque is large in size, it easily leads to carotid artery stenosis, causing poor blood flow and resulting in insufficient blood supply to the head, which in turn causes symptoms such as dizziness, headache and fainting. Although carotid endarterectomy can remove the plaque, it is generally used for people with carotid stenosis greater than 70%, or stenosis greater than 50%, but with symptoms such as dizziness and cerebral infarction, because there is some damage. Patients are advised to eat reasonably, exercise appropriately, quit smoking and limit alcohol, and can follow medical advice to stabilize the plaque by taking oral statins and aspirin to prevent further expansion.
