Many people may not know much about smog, or even have never heard of it. It is important to know that smog is a very dangerous cerebrovascular disease that has a big impact and can cause serious problems such as cerebral infarction and cerebral hemorrhage if not treated effectively, which can endanger life and health. Therefore, when suffering from smog, it is important to recognize the seriousness of the problem and treat it early to avoid aggravation. Smoky disease is a special kind of cerebrovascular malformation, which is caused by the narrowing or even occlusion of the main branches of the cerebral artery ring, resulting in an abnormal network of small vessels at the base of the skull, which resembles smoke during cerebral angiography. Once the diagnosis of smog is confirmed, treatment cannot be slowed down, and for the treatment of smog, conservative medication is not very effective, and surgery is needed for better control. Can smog be cured by unilateral surgery? As long as the right surgical method is used and active post-operative care is provided, recovery can be helped. In general, the typical case of smoker’s disease is that the patient has smoker’s lesions on both sides of the brain, in which case both sides need to be operated on, and the two surgeries cannot be performed at the same time, usually 3 to 6 months apart. Of course, there are some atypical cases where the patient only has unilateral smoldering lesions and only one side of the brain needs to be operated on unilaterally. Regardless of whether the lesion is bilateral or unilateral, effective surgical measures are needed to control the condition in a timely manner. Combined vascular bypass surgery is a treatment that has helped many patients with smog to solve their problems. Combined vascular bypass surgery combines the two methods of bypass and patching to improve blood flow to the brain, and the postoperative results are very satisfactory and reliable.
