Cerebrovascular disease, commonly known as stroke, has now become the first cause of death among our nationals. And about 80% of strokes belong to cerebral ischemic strokes and another 20% are caused by cerebral hemorrhagic strokes. Among these ischemia-induced stroke patients, most of them are caused by the narrowing or occlusion of blood vessels in the neck, resulting in insufficient blood supply to the brain, or plaque or thrombus in the cervical vessels coming off into the brain, causing cerebral infarction. Therefore, stroke can be prevented if the vascular lesion in the neck can be corrected to restore normal blood flow to the brain, which means that more than half of the stroke patients can be prevented by surgery. This surgery is called carotid endarterectomy, or CEA for short, which has been performed for more than 50 years abroad and is now a mature technique and a very common procedure abroad. However, in China, only a few large hospitals are currently performing this procedure, and only 1000 cases are performed each year. Carotid endarterectomy is to remove the atherosclerotic plaque and thrombus formed on the intima of the artery, so as to achieve the purpose of opening the blood vessels and restoring the blood supply to the brain. Recently, CEA has been successfully carried out in our hospital. With the gradual promotion of this technology and people’s recognition of this technology, more elderly people in our city will surely benefit from CEA surgery to avoid the occurrence of stroke. So which patients are suitable for CEA surgery? For patients with severe carotid stenosis, greater than 70%, one or more transient ischemic attacks or mild strokes within six months, or those with progressive transient ischemic attacks, surgery has the best prevention effect. Second, patients with frequent transient ischemic attacks, such as transient unconsciousness, sudden loss of vision, or sudden dropping of chopsticks while eating, are often referred to as “mini-strokes”. Third, if a person has recovered well from a stroke but has carotid artery stenosis, he or she may have another stroke in the future, which may lead to a complete stroke. Fourthly, the carotid artery is found to have sclerotic plaque, uneven plaque, and ulcers in the section should also be treated surgically. We suggest that people over 50 years old, especially those with hypertension and diabetes, should be aware of self-prevention and should have regular ultrasound examination of carotid arteries for early detection of carotid vascular lesions, and for patients with symptoms of cerebral ischemia and severe narrowing of carotid vessels, active measures should be taken to effectively control the “stroke” tragedy in the bud. The tragedy of “stroke” can be effectively controlled in the bud.
