The carotid artery supplies blood to our brain all the time to ensure the normal functioning of the brain. However, the problem of carotid artery stenosis makes the blood supply channel to the brain blocked and the blood supply is insufficient, which is a direct threat to health. The most common danger of carotid stenosis is cerebral infarction and stroke, so early treatment is needed to avoid serious development of the problem as much as possible. Of course, there is no need to panic and be overwhelmed when carotid stenosis is detected, as the severity of the disease is a fact, but modern medicine has become more and more developed, and there are good methods for the treatment of carotid stenosis. Grading of carotid artery stenosis In medicine, there are different levels of carotid artery stenosis, with stenosis below 50% being mild carotid artery stenosis, 50% to 70% being moderate carotid artery stenosis, and above 70% being severe carotid artery stenosis. Some patients exhibit very severe symptoms, such as dizziness, nausea, vomiting and blurred vision and unchanged limbs, although some patients may also have no obvious outward symptoms. Severe carotid stenosis requires aggressive surgical treatment Does severe carotid stenosis detected at the age of 72 without symptoms require surgical treatment? The answer to this question is yes. Carotid artery stenosis has reached a severe grade and requires aggressive surgical treatment even if there are no symptoms at this time. This is because when severe carotid stenosis develops, the lumen of the carotid artery has become very thin and blood flow is greatly reduced, which is very dangerous if not treated actively. Carotid endarterectomy At present, for the treatment of carotid stenosis, our neurosurgery team has developed a very advanced and mature technique, namely carotid endarterectomy, which can peel off the sclerotic plaque in the carotid lumen, restore the blood flow and change the blood supply to the brain. The procedure is performed under a microscope and is very safe. Our team is very good at the operation of carotid endarterectomy, and has accumulated rich experience over the years. Carotid endarterectomy is the standard procedure for the treatment of carotid artery stenosis and prevention of cerebral infarction in both domestic and international medical communities.
