The importance of the carotid artery in the human body: It is not an exaggeration to say that the carotid artery is the lifeblood of the human body, because with the existence of the carotid artery, the blood from the human heart can be continuously delivered to the brain, so that the brain can function and work normally. However, carotid artery problems often occur, such as carotid stenosis or even carotid blockage, which can directly affect the blood supply to the human brain and are dangerous. Carotid artery stenosis surgery indications: Carotid artery stenosis, carotid artery blockage is more powerful is to lead to brain infarction and brain hemorrhage and other problems, each patient needs to recognize the seriousness of the problem, early to the hospital to receive treatment, so as to avoid their own suffer more pain and suffering. Regarding the treatment of carotid artery stenosis, some hospitals take medication. However, medication can only work for patients with mild stenosis. For stenosis greater than 50% with obvious symptoms, stenosis greater than 70% without symptoms and blockage, surgical treatment is required. Surgical treatment for carotid artery stenosis: What surgery is performed for carotid artery blockage? Commonly, carotid stenting and carotid endarterectomy are used, but after a series of clinical verification, carotid stenting has many problems and the postoperative effect is not ideal. Therefore, carotid endarterectomy is generally recommended. Carotid endarterectomy was widely used in Europe and the United States in the early days, but this technique has not been commonly carried out in China. In recent years, carotid endarterectomy has been performed clinically to treat carotid stenosis. This procedure is performed under a microscope to precisely locate the lesion causing the blockage and remove the plaque to restore the normal size of the lumen and smooth blood flow.
