The main blood supply to the brain is the carotid artery, which is why it is often said to be the health barometer of the human brain. Once carotid artery stenosis occurs, the blood supply to the brain is bound to be greatly affected, and without active treatment and control, it can lead to serious problems such as cerebral infarction, the consequences of which are unimaginable. The danger of carotid stenosis is something that patients must pay attention to, and timely and effective treatment of carotid stenosis is very critical. What are the treatment options for carotid stenosis in the elderly? Generally speaking, there are two treatment methods for carotid stenosis, namely medication and surgery. For patients with less than 50% carotid stenosis and no symptoms, the stenosis can be controlled by medication. However, if the carotid stenosis is greater than 70%, surgical treatment is required. Many people may feel worried when they hear that surgery is required, imagining that cold surgery is risky, especially for older people, whose families have various concerns if they have to undergo surgery. It is understandable to have concerns, but it must be recognized that carotid stenosis and other similar cerebrovascular diseases are mostly found in the elderly, and not actively treated and controlled can lead to serious problems such as cerebral infarction, which must be treated scientifically and effectively. At present, the more effective treatment for carotid stenosis is carotid endarterectomy, a technique introduced from abroad, and after continuous development and improvement, it is now a very mature procedure, so patients can rest assured. Carotid endarterectomy is very safe, and the entire procedure is performed under a microscope, with a small incision for quick recovery, allowing the removal of the diseased carotid intimal plaque and restoring the carotid artery to its original health. However, in order to ensure the safety of the procedure, elderly patients should undergo a comprehensive examination before the procedure to exclude the presence of liver and kidney diseases.
