Smog is a relatively rare disease, but the incidence of this disease has increased in recent years, and many people only find out that they have smog when they go to the hospital with certain mild symptoms. Some people have mild headaches, numbness and weakness. In fact, smog is a cerebrovascular disease with an unclear cause. It is mainly caused by the narrowing or occlusion of the main arteries at the base of the brain, followed by the growth of many abnormal small blood vessels, which affects the blood supply to the brain and can be dangerous if not treated in time. In clinical practice, most smog patients start with headache and dizziness, and some patients also have weakness, aphasia, impaired consciousness and sensory impairment, but as mentioned above, there are also many patients who do not have any serious symptoms or whose symptoms are not serious and are basically the same as normal people. Is it necessary to operate for smog that is not serious? I believe that many patients have this question, but it should be reminded that even if the symptoms of smog are not obvious or serious, they must be taken seriously because smog is a chronic progressive disease that deepens and worsens in a subtle way, and if it is not treated in time to cause cerebral infarction and cerebral hemorrhage, the damage will be even greater. Smoke disease should be treated in a timely manner, and as far as the current treatment is concerned, it does not make much sense to rely on conservative medication alone. The traditional surgical method is direct bypass or patching, but these two methods are still somewhat single in treatment, and sometimes the postoperative recovery effect may not be ideal.
