Calcified plaque in the cavernous sinus segment of internal carotid artery is usually caused by risk factors such as hypertension, hyperlipidemia and diabetes mellitus, which leads to carotid vascular damage and then calcified plaque. Plaque progression can be slowed down or eliminated by controlling the diet, controlling the underlying diseases and surgical treatment. 1. Dietary control: Patients with less severe plaque can delay plaque progression by dietary control, avoiding excessive intake of sugary and fatty foods such as cream, fried foods, fatty meat, etc., moderate aerobic exercise and weight control. 2. Control underlying diseases: delay the progress of carotid plaque by controlling blood pressure and blood lipids. Patients with high blood pressure can take antihypertensive drugs such as amlodipine benzenesulfonate tablets, and patients with high blood fat can take lipid-lowering drugs such as Rosuvastatin tablets, which should be used under the guidance of a doctor. 3. Surgery: If the degree of carotid artery stenosis is more than 70%, or more than 50% but with symptoms, carotid plaque can be eliminated through carotid endarterectomy, carotid stenting and other surgeries. It is recommended that patients with carotid plaque should seek medical treatment in time, and the doctor should make a clear diagnosis and then treat them actively in order to avoid serious consequences.
