Some patients may have sudden dizziness or even fainting, weakness of limbs, intellectual decline, etc., and when they go to the hospital for a serious investigation, they are found to have carotid artery occlusion. Carotid artery occlusion will lead to the blood can not be timely blood supply for the brain, thus appearing some of the above symptoms of cerebral ischemia, this situation is very dangerous, or can be life-threatening. Carotid artery disease is mainly in the middle-aged and elderly people, they suffer from carotid artery stenosis or even occlusion of the chances are very high, because most of the people suffer from high blood pressure, diabetes, hyperlipidemia, thick blood fat, etc., coupled with poor dietary habits of smoking and drinking, etc., are prone to aggravate atherosclerosis, and therefore caused by the carotid artery stenosis or occlusion. Many patients or their family members are very afraid and panic when they hear the hospital say carotid artery occlusion, because the answer given by the hospital is usually that there is not much hope for treatment or the effect of the surgery cannot be guaranteed, and some hospitals suggest conservative treatment and continued observation, which not only puts them into a sad and negative atmosphere, but also puts them in danger of acute cerebral infarction at any time and any place due to the failure to receive timely and useful treatment. The patient will be in danger of having an acute cerebral infarction at any time. So can carotid artery occlusion be operated? The answer is yes, at present, for carotid artery stenosis of moderate to severe, that is, the usual check out the carotid artery stenosis rate of more than 50%, and there are obvious symptoms, it is necessary to use more effective carotid artery endothelial stripping surgery for surgical treatment. If the carotid artery is narrowed and occluded, it is suitable to be treated by cerebrovascular bypass surgery, which can restore the blood flow by establishing the blood supply channel of the side branches, ensure the normal blood supply, and prevent the occurrence of cerebral infarction.
