The carotid artery is a major artery that is indispensable to the human body. When carotid stenosis occurs, it can lead to insufficient blood supply to the brain, and in severe cases, it can cause cerebral infarction or even death. The consequences of carotid stenosis can be unimaginable, so patients should pay attention to it and actively receive effective treatment to better avoid the pain caused by the disease. Clinical studies have shown that patients with carotid artery stenosis are much more likely to have a stroke than the general population, and that carotid artery stenosis is a major disease that threatens human health. However, it is important to recognize that not all patients with carotid stenosis can be cured by taking medication. For example, mild carotid stenosis can be controlled with medication, but moderate to severe carotid stenosis (greater than 50% stenosis) can be treated with dissection surgery depending on the circumstances. What are the disadvantages of stripping surgery for 80% carotid stenosis? It can be clearly stated that there are certain risks associated with any surgery, and carotid dissection surgery is no exception. Therefore, in order to better ensure the safety and postoperative results of carotid artery stripping surgery, it is important to choose a regular hospital and a professional doctor to perform the surgery, because only a professional doctor can take the appropriate precautions in these areas. Carotid endarterectomy is done under a microscope to better ensure the safety of the procedure, which is currently the more ideal surgical method for treating moderate to severe carotid stenosis. It can achieve the purpose of stripping the carotid plaque, restoring the size of the internal diameter of the carotid artery and the smoothness of the inner wall of the carotid artery, thus improving the condition of the blood supply to the brain. The surgical incision is small and the operation time is short, and the patient can return to normal life in 1-2 days after the operation.
