The carotid artery is a vital part of the body, the blood from the heart is transported to the head and face through the carotid artery, if there is a problem in the carotid area, the consequences are very powerful. There are many patients who suffer from carotid artery stenosis, so the blood cannot be transported and supplied properly, and the brain’s operation and work are affected, which is really dangerous. Carotid artery stenosis is a common cause of cerebral ischemia and cerebral infarction, which can have a great impact on health and can even be life-threatening. Therefore, when diagnosed with carotid stenosis, patients must adjust their mindset, realize the importance of the problem, and receive treatment in a timely manner at a regular hospital to reduce the damage caused by the disease to themselves. Is carotid artery surgery a major surgery? At present, some hospitals in Nanjing may also have treatment about this, but most of them take conservative medication in the treatment. If the degree of stenosis is more than 50% and the patient has obvious symptoms, then medication alone may not achieve the desired effect and surgical treatment is required. Currently, the main surgical methods for treating carotid stenosis are carotid artery stenting and carotid artery endothelial debridement surgery, but after a lot of clinical verification, it is concluded that there are some problems after carotid artery stenting surgery and the results are not ideal. For better treatment of carotid stenosis, carotid endarterectomy is recommended.
