The carotid artery plays an irreplaceable role in the functioning of the entire body. It is an important blood supply channel that connects the heart to the brain. It is because the carotid artery is able to supply blood to the brain properly that the brain can work properly and dominate every part of the body. Many people suffer from carotid artery stenosis, and as a result, the blood supply to the brain is disrupted and the problem is very serious. What is carotid artery stenosis? Many people may not understand what carotid stenosis is. In fact, it is a common cerebrovascular disease, which is mainly caused by atherosclerosis of the carotid artery, resulting in problems such as hyperplasia, ulceration or calcification of the carotid artery intima, followed by the formation of plaque, resulting in the narrowing of the carotid artery lumen. When the carotid artery is narrowed, the plaque in the carotid artery lumen will easily slip off, which will easily form thrombus and cause acute cerebral infarction, which is very dangerous to human life and must be examined and treated early. Carotid artery stenosis is a disease that cannot be seen by the naked eye, so patients should go to the hospital for examination when there are abnormalities in the body, so that the disease can be diagnosed and investigated. Carotid artery stenosis is a neurological disease, patients should choose to go to the hospital is generally registered neurology or neurosurgery, but the situation of each hospital is different, not necessarily what department is registered, it is recommended that patients go to the hospital to consult the medical guide desk. There are several methods used to examine and diagnose carotid artery stenosis: Doppler ultrasonography, MRI angiography, CT angiography and digital subtraction angiography. Once carotid stenosis is diagnosed, it is important for patients to actively cooperate with treatment to better control the condition and avoid more serious damage. Carotid endarterectomy has good effect At present, many patients choose to come to our hospital for treatment of carotid stenosis, and I can say without modesty that our neurosurgery department for cerebrovascular disease is quite outstanding. We use carotid endarterectomy. Carotid endarterectomy is the ideal treatment for carotid artery stenosis because of its high safety, good postoperative recovery, and highly positive results.
