The common cause of cerebrovascular stenosis is atherosclerotic plaque formation, which can lead to ischemic stroke, resulting in hemiparesis, aphasia, and other conditions that affect the normal quality of life, and even endanger life. Cerebrovascular stenosis can be categorized according to the degree of stenosis into mild stenosis (<50%), moderate stenosis (50% to 70%) and severe stenosis (>70%). However, not all cerebral stenosis can lead to ischemic stroke, and it can be prevented by medication and surgery, so it is not the end of your life if you have cerebral stenosis. If cerebral stenosis is detected, it is recommended to consult a professional physician and standardize the use of medication under the physician’s guidance, and assist in surgical treatment when necessary to prevent stroke.
