There are many blood vessels throughout the body, and healthy blood vessels carry nutrients for the whole body, while some other blood vessels are prone to plaque formation due to the accumulation of waste deposits, causing stenosis and obstructing vascular transport, causing a series of discomfort. Carotid artery is one of the common blood vessels prone to stenosis in clinical practice, which is easily triggered by the presence of atherosclerotic plaque. Carotid stenosis is a cerebrovascular disease that seriously threatens the life safety of patients and can easily cause very serious consequences, so it is important to pay more attention to it and seek medical treatment in time after its discovery. Typical symptoms of carotid artery stenosis 1. Insufficient blood supply to the brain After the carotid artery has a class block, the lumen of the blood vessel will become narrower, the blood flow will be greatly reduced, and the blood cannot enter the brain in time, which will easily cause insufficient blood supply to the brain. Insufficient blood supply to the brain will result in insufficient supply of oxygen and nutrients for normal brain operation, which will cause drowsiness, memory loss, dizziness, loss of vision, tinnitus, inability to concentrate, and in severe cases, numbness of limbs and inability to move, or even loss of consciousness and inability to speak. 2. Affects cognitive ability After carotid artery stenosis occurs, patients will experience significant memory loss. Many studies at home and abroad have shown that most patients with carotid artery stenosis will have different degrees of decline in movement, learning and memory, which seriously affects patients’ life and work. 3, cerebral infarction Once the atherosclerotic plaque is dislodged, a thrombus will be formed, and the thrombus will block the cerebral vessels and then form a cerebral infarction. Research shows that 60% of cerebral infarction and carotid artery stenosis, cerebral infarction will bring significant harm to patients, paraplegia, partial paralysis or even death, causing serious physical and mental harm to patients For carotid artery stenosis resulting in insufficient blood supply to the brain how to do? When carotid artery stenosis occurs, the lumen becomes narrow and the blood flow is not smooth, which easily leads to cerebral ischemia. Since the cerebral blood supply is insufficient, we improve the cerebral blood supply through a method. The scientific treatment plan for carotid artery stenosis is to use surgery as the main treatment, supplemented by medication. Carotid endarterectomy is an ideal technique for treating carotid stenosis, which can effectively remove atherosclerotic plaque, improve cerebral blood supply, and greatly reduce the chance of cerebral infarction.
