The health of the carotid artery is directly related to the health of the human body, because the carotid artery is the main channel of blood supply to the brain, once suffering from carotid artery disease, it will definitely affect the blood supply to the brain, if the brain blood supply is insufficient, the impact is far-reaching. Carotid artery stenosis is one of the most common cerebrovascular diseases at present. The problem of carotid artery stenosis and the lack of blood flow in the blood vessels have very serious consequences, so it needs to receive regular and effective treatment in a timely manner. For the treatment of carotid stenosis, it is divided into cases. Generally speaking, mild carotid artery stenosis does not affect blood flow very much, and patients do not have obvious ischemic symptoms. If the stenosis is already moderate to severe, surgery should be considered to better control the condition. For surgical treatment of carotid artery stenosis, carotid endarterectomy is preferred, which is the ideal treatment for moderate to severe carotid artery stenosis and is the standard procedure to prevent cerebral infarction caused by carotid artery stenosis. How risky is carotid endarterectomy? In fact, since the successful use of carotid endarterectomy, this technology has become very mature, with many successful clinical treatment cases, low surgical risks, and good postoperative recovery, and the choice of treating moderate to severe carotid stenosis through carotid endarterectomy is completely safe. As long as the patient has no heart or kidney problems and no special underlying diseases, they can safely undergo carotid endarterectomy, and all precautions regarding risks will be taken before surgery, so patients can rest assured.
