In clinical practice, carotid plaque is easily dislodged. Once the carotid plaque is dislodged, it will enter the patient’s blood vessels in the brain directly with the blood flow of the carotid artery, causing the patient to have a stroke, and then the patient will have dizziness and headache. Some patients may even experience visual impairment and some patients may experience limb dysfunction, so it is important to pay sufficient attention to carotid plaque. Once a patient finds a carotid plaque, it is recommended that he or she should go to the hospital in time for consultation and appropriate treatment. If the carotid plaque affects the blood flow in the carotid artery, the patient should be treated accordingly, such as atorvastatin and aspirin for anticoagulation, depolymerization and plaque stabilization, which can help prevent stroke. In addition, if the carotid plaque affects more than 70% of the carotid blood flow, it is better to perform carotid plaque debridement, and to debride the carotid intima, so that the patient can recover healthily.
