When hearing about smog disease, most people can’t help but associate it with smoking and haze. However, it is not as we think, smog disease is a rare cerebrovascular disease, usually occurring in children and young people, the cause of the disease is not clear, but it is very harmful, once the disease should be actively dealt with. Clinically, smog disease can be roughly divided into two types, namely ischemic smog disease and hemorrhagic smog disease, ischemic smog disease patients will have headache, transient limb weakness, aphasia and other symptoms, may also be accompanied by impaired consciousness, visual impairment, etc., and severe will cause cerebral infarction and hemiparesis; while hemorrhagic smog disease is mostly manifested as intracerebral hemorrhage and subarachnoid hemorrhage, the onset of the onset of the disease are generally more acute, and the risk of death may even cause. The onset of hemorrhagic smog disease is usually more rapid and dangerous, and may even cause death. The disability and mortality rates of smog disease cannot be underestimated, so it is important to actively cooperate in the treatment of smog disease when you know you have it. Currently, there is a consensus among medical experts that the only way to treat smokers is through surgical procedures, which have a better prognosis. Is it better to use a bypass or a patch for smoky skin? In fact, direct bypass and patch surgery have their own shortcomings, for example, direct bypass surgery to improve the blood supply to the brain is limited, and patch surgery, although simple, but the postoperative period of blood vessel formation is too long, which is not without the possibility of cerebral infarction, stroke.
