Carotid stenosis has now become a very common cerebrovascular disease, posing a great risk to people’s health, especially the health of the middle-aged and elderly. Carotid stenosis can cause cerebral ischemia and cerebral infarction, and severe cerebral infarction can be disabling or even fatal. Therefore, carotid stenosis should be treated promptly. Carotid stenosis is mostly caused by atherosclerosis, which is the most common cause. For the treatment of such atherosclerotic carotid stenosis, mild stenosis (that is, stenosis rate of 50% or less) can be treated conservatively, while moderate to severe carotid stenosis needs to be treated surgically depending on the situation, and carotid endarterectomy is currently the internationally recognized preferred surgical procedure. So which department do I need to register for endarterectomy for carotid stenosis? Endarterectomy for carotid stenosis requires neurosurgery, because carotid stenosis involves cerebral ischemia, cerebral infarction and other cerebral nerve functions, and it is also a surgical treatment, so it should be registered with neurosurgery, and currently most of the carotid endarterectomies are carried out by neurosurgery. Carotid endarterectomy is a very advanced and effective way to treat moderate to severe carotid stenosis, and has become a standard procedure. Carotid endarterectomy is performed under a microscope and is very safe. The procedure is performed in the neck and a 6-8 cm incision is made to fully free the carotid artery, cut the canal wall, peel out the diseased intimal plaque, restore the lumen inner diameter size, restore blood flow, and achieve ideal blood flow reconstitution with good clinical results. The procedure does not take long, 1-2 hours to complete, and the patient can return to normal life 1-2 days after the procedure.
