Once a person enters old age, all body functions gradually deteriorate, and many diseases are available. The carotid artery is an important bridge between the brain and the heart, and when the carotid artery is narrowed, it naturally affects the blood supply to the brain, thus causing a lot of physical damage to the patient. Clinically, most carotid stenosis is caused by atherosclerosis, especially in the elderly, as the blood vessels age, blood lipids are deposited and attached to the walls of the vessels, leading to thickening of the carotid intima and the formation of plaques, which will block the carotid artery channels and lead to poor blood flow. Mild carotid artery stenosis will show chronic ischemia, while severe carotid artery stenosis will easily cause cerebral infarction and other problems, and the consequences are even more unimaginable if not treated and controlled in time. Therefore, once carotid artery stenosis is detected, it should be treated before it is too late to minimize the damage caused by the disease. Is carotid stenosis in the elderly suitable for surgery? If the carotid stenosis is mild, conservative treatment can be taken to control the growth of plaque and regular review, but if the carotid stenosis is severe, it should be treated with surgery in time if it meets the indications for surgery.
