In recent years, the incidence of carotid artery stenosis has gradually increased, becoming one of the top killers threatening human health. According to statistics, more than 60% of cerebral infarctions are caused by carotid stenosis, and severe cerebral infarction can be disabling or even fatal, and there is no shortage of cases of cerebral infarction caused by carotid stenosis, resulting in hemiplegia, disability or even death. Therefore, if you suffer from carotid stenosis, you should treat it as soon as possible. For the treatment of carotid stenosis, it depends on the severity of the disease. For mild carotid stenosis, conservative medical treatment, strict medication and regular review are recommended; while for more severe carotid stenosis, surgical treatment may be required depending on the situation. What are the indications for surgical treatment of carotid stenosis? This indication is very complex and requires a thorough evaluation by a medical professional in the hospital. Simply put, carotid artery stenosis of 50% or more with clinical symptoms or unstable plaque requires surgery; if carotid artery stenosis is more than 70%, surgery is required regardless of the presence of symptoms. Of course, some underlying diseases need to be excluded for surgical treatment. Currently, carotid endarterectomy is recognized as a standard surgical procedure for the surgical treatment of carotid artery stenosis, both at home and abroad. The procedure is performed under a microscope to cut open the carotid artery, peel off the hyperplastic plaque, smooth the inner wall of the carotid artery, restore the normal internal diameter, and restore the lumen of the carotid artery, which can effectively reduce the risk of stroke.
