There is a very important blood vessel on the left and right side of the neck called the carotid artery. The carotid artery is the main source of blood supply to the brain and is responsible for delivering nutrients and oxygen to the brain to keep the brain tissues functioning properly. However, under the influence of certain factors, the carotid artery can become narrowed, and blood flow can be reduced or blocked, leading to transient cerebral ischemia and ischemic stroke. Studies have found that there are many causes of carotid artery stenosis, the common one being atherosclerosis, while high blood pressure, high blood sugar, high blood lipids, and irregular life, smoking and drinking can accelerate the formation of atherosclerosis, therefore, middle-aged and elderly people who generally suffer from three highs become a high incidence of carotid artery stenosis. As each patient’s condition is different, the stenosis site is also individualized, with some patients having left-sided stenosis, some having right-sided stenosis, and some having bilateral stenosis. Is a 70% stenosis of the right uncinate artery dangerous and do I need surgery? There are two types of treatment options for carotid artery stenosis: conservative and surgical, and the choice of which one is needed depends on the degree of stenosis and the patient’s symptoms. In modern medicine, the degree of carotid stenosis is classified as such. When it is less than 50%, the patient can go to a regular hospital neurosurgery department for appropriate drug treatment. When it is higher than 50% and has significant symptoms such as dizziness, headache, insomnia, memory loss and hemiparesis, it is recommended to consider surgical treatment. In addition, for stenosis higher than 70%, surgical treatment should be done regardless of the associated symptoms. Therefore, patients with 70% stenosis of the right uncinate of the strong artery are in a more serious condition and are recommended to receive surgical treatment as soon as possible. Carotid artery endarterectomy for carotid stenosis has achieved good clinical results. The procedure can effectively get rid of atherosclerotic plaque, restore the lumen of the carotid artery, and greatly improve blood supply, which is very satisfactory. In addition, after carotid endarterectomy, patients must pay attention to diet, mainly light and easy to digest, not to eat spicy and stimulating food, avoid eating too greasy, high-fat and high-protein food, eat more fresh plants, green vegetables, more vitamin C-rich food, and also closely observe body weight, or hypertension, high blood pressure and high blood sugar, to avoid too high blood pressure.
