Some patients will suddenly dizziness or even fainting, weakness of the limbs, mental decline, etc., to the hospital a serious investigation, found that the carotid artery occlusion. Carotid artery occlusion will lead to blood can not be timely for the brain blood supply, and thus some of the above symptoms of cerebral ischemia, this situation is very dangerous, heavy can be life-threatening. Carotid artery disease is mainly in the middle-aged and elderly people, they have a high chance of suffering from carotid artery stenosis or even occlusion, because most people suffer from hypertension, diabetes, hyperlipidemia, thick blood lipids, etc., plus poor dietary habits such as smoking and drinking, are prone to aggravate the occurrence of atherosclerosis, thus causing the narrowing or occlusion of the carotid artery. Many patients or family members are very scared and panic after hearing the hospital say that the carotid artery is occluded, because the answer given by the hospital is generally that there is little hope for treatment, and some hospitals suggest conservative treatment and continued observation, which not only makes them fall into a sad and negative atmosphere, but also puts the patient at risk of acute cerebral infarction anytime and anywhere because they cannot receive timely and useful treatment. Can carotid artery occlusion be operated? The answer is yes. At present, for moderate to severe stenosis of the carotid artery, that is, if the stenosis rate of the carotid artery is more than 50% and there are obvious symptoms, the more effective carotid endarterectomy is needed for surgical treatment. In the case of occluded carotid stenosis, cerebrovascular bypass surgery is suitable for treatment to restore blood flow and ensure normal blood supply and prevent the occurrence of cerebral infarction by establishing the ate side branch blood supply channel.
