The health problems of contemporary people are really serious, and the incidence of all kinds of diseases has increased so much that people have to be more careful. Smog disease is a serious threat to health, it is a kind of cerebrovascular malformation, mainly the patient’s brain bottom of the main arterial vascular narrowing or occlusion of the problem, and then lead to the formation of many small blood vessel network, because the shape of the smoke, so that the name of the smoke disease. Most people with smog disease experience dizziness, headaches, poor concentration and memory loss. If left untreated, smog disease can affect the patient’s mental ability, and may even lead to aphasia and hemiplegia. Of course, not only these, smog disease condition deepens and aggravates, there will be cerebral infarction, stroke, cerebral hemorrhage risk, this time it becomes more difficult. Therefore, the earlier the smog disease is treated, the better it is for recovery. Currently, there are two main treatments for smog disease: conservative medication and surgery, but it is obvious that medication can only play a temporary role in relieving the symptoms, and cannot fundamentally improve the blood supply to the brain, so the treatment of smog disease is still to be done with the help of surgical means. So, smog disease has bilateral cerebral infarction, there is still a need for surgery? Recently, some patients asked this question, in fact, even if smokers have bilateral cerebral infarction, surgery is still necessary, because the purpose of surgery is to prevent and reduce the probability of recurrence of cerebral infarction and cerebral hemorrhage. If the surgery is not timely treated, then the risk of recurrence of cerebral infarction and cerebral hemorrhage in the later stage is still very high.
