Nowadays, more and more people are told that they have carotid stenosis after having carotid ultrasound or MRI, but do you know about the common causes and clinical treatment of carotid stenosis? The common cause of carotid artery stenosis is carotid atherosclerosis, which is the formation of plaques in the carotid artery wall. When these plaques increase in size or rupture, they cause carotid stenosis or embolism, which decreases the distal perfusion pressure and leads to hypoperfusion cerebral infarction, which seriously affects people’s health and quality of life. At present, many scholars believe that the occurrence of carotid atherosclerosis is related to the following diseases and other factors: 1, increasing age 2, hypertension 3, hyperlipidemia 4, diabetes 5, hyperuricemia 6, obesity, etc. Therefore, it is especially important to actively prevent and treat the above related diseases and other factors, such as: a light diet, non-smoking, active physical exercise, weight control, regular physical examination, and if there is If clinical symptoms such as headache and dizziness appear, early examination and treatment should be actively carried out in hospital. At present, interventional method (carotid stenting) is one of the main methods for the treatment of carotid stenosis, and the application of this treatment in ischemic cerebrovascular diseases provides a new method for the clinical treatment of carotid stenosis.
