As people get older, the probability of various diseases increases significantly. Cerebrovascular diseases are a serious health hazard for the elderly, and carotid stenosis is very common. When the carotid artery is narrowed, the blood from the heart cannot be transported to the head properly, and the brain is not supplied with enough blood to work and function properly, which has a great impact. If carotid stenosis develops to a certain extent, it can cause many serious symptoms and make patients suffer more. Common symptoms of carotid stenosis are dizziness, tinnitus, blurred vision, dizziness and headache, insomnia and dreaminess, memory loss, etc. If the development is serious, it may also induce cerebral infarction and stroke, and patients may suffer from hemiplegia, aphasia and other brain nerve damage. Carotid artery stenosis is harmful and has a high mortality rate, so once the disease is diagnosed, it should be treated at a regular hospital as soon as possible. Currently, there are two main methods of treatment for carotid artery: medication and surgery, of which medication is useful for mild carotid stenosis, while surgery is necessary for severe carotid stenosis. Are there any sequelae after carotid surgery? In the treatment of carotid artery stenosis, some hospitals may be able to perform surgical treatment, but most of them use carotid stenting. Although carotid artery stenting is useful, there are some inevitable problems after surgery, and the recovery is not very good, with a high rate of restenosis and the possibility of foreign body reaction, thrombosis in the stent, and stent fracture and collapse. Therefore, if you want to get better treatment, it is recommended to go to Beijing, the capital, where the medical level and technical equipment are more advanced.
