Carotid endarterectomy (CEA) is currently an international advanced technology in the treatment of stroke, and is also a method of stroke prevention and treatment with fewer complications, higher safety factor, and least cost to the patient, which is currently carried out by only a few large hospitals in China. Carotid endarterectomy for the prevention of cerebral infarction has a great potential for development in China, and it is believed that in the near future, carotid endarterectomy will become the most common routine operation in the operating room, just as it is in the western developed countries. The treatment of carotid artery stenosis includes carotid artery stenting (CAS) in addition to surgical treatment (CEA). To date, carotid endarterectomy (CEA) is still considered the standard treatment for carotid stenosis, and stenting is an effective complementary treatment for patients with symptomatic carotid artery stenosis, rather than an alternative. The procedure is currently performed in more than 100,000 cases per year in the United States, while there are less than 1,000 cases per year for our 1.3 billion population. The reasons for this are related to the low level of access to medical care in China, the low number of patients screened, and the lack of patient awareness of the dangers of carotid artery stenosis. Cerebrovascular disease prevention knowledge should be increased popularization of science propaganda, to clearly inform patients of the harm of carotid artery stenosis, as soon as possible to remove the carotid artery vascular “garbage”, reduce the risk of cerebral infarction, so as to avoid the loss of the best time for treatment in the emergence of a serious stroke only to come to the doctor. We would like to remind everyone that once there is transient weakness or dizziness, sudden visual impairment or black haze, sudden severe headache or difficulty in walking, you should go to the hospital immediately, do not blindly treat, especially not as a cervical spondylosis massage, so as not to cause unstable plaque dislodgement leading to cerebral embolism. For people with high risk factors for occlusive cerebrovascular disease, such as those over 40 years old, with hypertension, diabetes mellitus and atherosclerosis; those who often have dizziness and discomfort; and those who have symptoms of transient cerebral ischemia or a history of transient cerebral ischemia, carotid ultrasonography should be done once a year.
