The carotid artery is an important bridge connecting the brain and the heart, and the blood to the human brain and face is basically delivered through the carotid artery. Once the carotid artery is narrowed, the blood flow channel is not smooth and the blood supply to the brain is insufficient, which can cause many serious problems. Most of the more common cerebral hemorrhage and cerebral infarction in life are caused by carotid artery stenosis, so when suffering from carotid artery stenosis, you must be alert and take active measures to treat it in order to reduce the damage. For the treatment of carotid stenosis, there are currently two medical treatments, one is medication, which can only treat mild carotid stenosis, and the other is to carry out surgical treatment. There are two kinds of surgical treatment: endarterectomy and stent implantation. Is it better to put stents in carotid stenosis or endarterectomy? Many patients do not know how to choose and are confused. At present, the surgical treatment of carotid stenosis in China is not very developed, and many hospitals may use carotid stent implantation for the treatment of carotid stenosis, but stent implantation actually has many unavoidable problems. However, there are many unavoidable problems with stenting, such as dislodging of the embolus, formation of intra-stent thrombosis and restenosis. The current international standard procedure for the treatment of carotid stenosis is carotid endarterectomy, a method that directly peels away the carotid plaque and the diseased intima, restores the original size of the carotid lumen, and reestablishes blood flow. The procedure is very safe, the recovery is fast, and the results are obvious, making it a very mature treatment technique.
