Restricted stenosis of cerebral arteries may be caused by atherosclerosis, vasculitis, congenital factors, common sites such as the beginning of the blood vessels, bifurcation, it is recommended that further examination to clarify the cause of the disease and then treatment.
1. Atherosclerosis: the most common cause is the abnormality of lipid metabolism in the body, which leads to a large amount of lipid deposition in the arterial wall, and gradually form lipid-like atherosclerotic plaques, leading to atherosclerosis and stenosis of blood vessels, which may cause cerebral infarction in severe cases, and the discovery of atherosclerosis needs to be taken by the doctor as prescribed by the statin class of lipid-lowering and stabilizing drugs.
2. Vasculitis: seen in acute arteritis, the wall of the blood vessel due to the development of inflammation, thus causing wall thickening, resulting in the internal diameter of the blood vessel becomes smaller, the wall of the tube is narrowed.
3. Congenital factors: such as congenital vascular anomalies, thus causing vascular stenosis.
If there is limited narrowing of cerebral arteries, you can check the blood lipids, blood pressure, cranial nuclear magnetism, etc. to find out the cause, and then diagnose and treat under the guidance of doctors.
