With the accelerated pace of life and changes in lifestyle, many diseases today are no longer exclusive to the middle-aged and elderly, but have gradually tended to become younger. Carotid artery stenosis is one of the most prevalent diseases today, and every year many people are found by chance during medical examinations before they pay attention to it. The carotid artery can be called the lifeblood of the brain without exaggeration, because most of the blood from the heart to the head and neck needs to pass through this important channel, so it can be said that it is closely related to the blood supply to the brain and is a very important blood vessel, so it is important to protect it. Despite all the precautions, there are always people who accumulate garbage in the carotid lumen for various reasons, forming atherosclerotic plaques and causing carotid artery stenosis. Carotid artery stenosis cannot be ignored because it slows down blood flow, which may cause dizziness, blurred vision and memory loss in mild cases, or cerebral infarction and other adverse consequences in severe cases, posing a great threat to health. Once carotid artery stenosis is diagnosed, early treatment is crucial. For less serious cases, on the one hand, we should follow the medical advice and take the medication on time to avoid the problem from becoming more serious; on the other hand, we need to control the three highs, avoid greasy and high-fat food in daily life, we should mainly eat light, eat more vegetables and fruits, and strengthen the exercise appropriately to keep the blood vessels young. If the condition is more serious, surgical treatment can be considered. Some people ask how much carotid artery stenosis surgery can be reimbursed. The specific cost of this surgery has a great deal to do with the patient’s specific condition and the surgical method chosen, and the reimbursement needs to be based on the policies of the participating hospitals. For example, some local hospitals may adopt carotid artery stenting, which is slightly less expensive; however, there are some problems with stenting, such as the formation of thrombosis during surgery and the need for long-term medication after surgery, which may result in a higher chance of restenosis. Carotid endarterectomy, a technique that finds the carotid artery under microscopic observation, removes the plaque causing the stenosis, restores the carotid artery wall and internal diameter to normal, and restores blood flow, with very good results.
