The carotid artery is an important blood vessel in the neck of the human body and is an important hub for transporting blood from the heart to the head and face. When people get older, blood vessels become old and blood lipids tend to accumulate, forming atherosclerosis, making the carotid artery lining gradually thicken, so this disease mostly occurs in middle-aged and elderly people, so what should be done for the elderly with severe carotid stenosis? Studies have found that most patients with carotid stenosis have symptoms such as tinnitus, dizziness, dizziness, blurred vision, dizziness, headache, insomnia, memory loss, drowsiness, and dreaminess. A small number of patients may also experience transient ischemic attacks, resulting in transient local neurological deficits, but these tend to be transient and reversible and usually recover within 24 hours. Patients may also suffer acute cerebral infarction due to dislodgement of carotid plaque, which is often sudden and very dangerous. The treatment of carotid arteries is divided into two cases. For mild carotid stenosis with a stenosis rate of less than 50%, medical medication is recommended to alleviate further aggravation of the condition. For patients with carotid stenosis with a stenosis rate greater than 50, prompt surgical treatment is required. Carotid endarterectomy, which has been well treated for many patients with carotid stenosis from all over the country, is widely acclaimed. This procedure has been widely recognized and advocated by the medical community for its excellent efficacy in removing the diseased intima under the microscope and restoring the normal size of the internal diameter.
