In recent years, various types of cardiovascular diseases have gradually become more prevalent, seriously threatening people’s life and health. In particular, there is a disease called carotid artery stenosis, which is extremely dangerous. It is understood that this is a very common cerebrovascular disease in the middle-aged and elderly population, which can cause insufficient blood supply to the brain, and in serious cases can lead to acute cerebral infarction, with terrible consequences, and even fatal. Therefore, once you suffer from carotid stenosis, you must pay attention to it and seek medical treatment in a timely manner. In general, for mild carotid stenosis with less than 50% stenosis, conservative medical treatment is recommended to control the plaque; while for moderate to severe carotid stenosis with more than 50% stenosis, surgical intervention should be performed depending on the situation, especially for patients with symptoms of cerebral ischemia or stenosis rate greater than 70% or unstable plaque, they should actively receive surgical treatment. Some patients ask about the cost of carotid artery stenosis surgery. In fact, the most advanced and effective surgical procedure for the treatment of moderate to severe carotid stenosis is carotid endarterectomy, which is not expensive and should be affordable for the average family. Carotid endarterectomy was first performed by foreign medical experts in the 1950s and has since been established as the standard procedure for the treatment of moderate to severe carotid stenosis and prevention of cerebral infarction, and has been developed over the past 70 years with very mature and safe technology. The procedure is performed under a microscope and can completely remove the carotid plaque that causes stenosis, restore blood flow in the carotid artery, improve cerebral blood supply, and achieve ideal treatment results, which is widely praised by patients.
