Classification of carotid stenosis

Carotid artery is a large blood vessel that transports blood from the heart to the head, face and neck. It is one of the main blood vessels supplying blood to the brain. Carotid artery stenosis is mostly caused by atherosclerotic plaque in the carotid artery, and its incidence is relatively high. Carotid artery stenosis is 0-50%, which is mild stenosis. At this time, the impact on blood flow is not great. There may be no symptoms, but it should be highly valued. Risk factors related to treatment, such as hypertension, hyperglycemia and hyperlipidemia, etc., should be given up smoking if smoking, and neck vascular color Doppler ultrasound should be reexamined every six months. If the stenosis rate reaches 50%-70%, it is moderate stenosis. If the stenosis rate exceeds 70%, it is severe stenosis. If the carotid artery is severe stenosis, it should be severe. The carotid artery lumen is already thin and the blood flow is low. At this time, surgery should be performed regardless of symptoms. The standard surgical method is internal carotid endarterectomy. Other treatment modalities include interventional therapy, such as percutaneous transluminal angioplasty of the internal carotid artery, carotid stenting and so on.
