Carotid artery plaque thickness of 32 or 3.2mm, carotid artery plaque > 1.2mm belongs to carotid artery stenosis, at this time, we should consult a doctor in time, and give surgical or interventional treatment. 1. Surgical treatment: open carotid endarterectomy can be used to remove the plaque and endothelium, restore the lumen of the artery, restore the blood flow rate to normal, and at the same time, avoid the formation of thrombus in the local stenosis, which may cause cerebral infarction due to the dislodgement of thrombus. 2. Interventional therapy: For older patients, especially those who cannot tolerate open surgery, carotid artery stenting can be used to open the carotid artery lumen and restore blood flow. Patients with carotid plaques should pay attention to diet, limit salt intake, quit smoking and alcohol, insist on appropriate exercise, maintain a relaxed mood and stress, etc., to ensure that sleep, avoid staying up late. If the patient has insufficient cerebral blood supply, carotid artery stenosis, should promptly go to the hospital for appropriate examination and standardized treatment, so as not to delay the condition.
