Smoke disease is not common and few people have heard of it. In fact, smoke disease is caused by progressive narrowing or occlusion of the main branch blood vessels of the brain, resulting in abnormal proliferation of the vascular network at the base of the skull and the formation of smoke vessels, which leads to a series of symptoms. Patients with smoker’s disease have mainly ischemic and hemorrhagic symptoms during attacks, mostly manifested as headache, dizziness, weakness and numbness of one or both limbs, aphasia, hemiparesis, etc. How many stages of smog and can smog be cured in late stages? There are six stages of smog, and as with most diseases, from stage 1 to stage 6, smog only progresses in a more serious direction, so it is important to receive treatment in a timely manner once smog is detected. Since the first case of smog was discovered, the medical community has not given up exploring it, but domestic medical experts know very little about it, so many smog patients cannot be treated effectively despite being diagnosed, and the mortality rate of smog patients within 5 years rises to 80%. Can smog be cured in advanced stages? The most important prerequisite is to choose the best procedure and the best hospital for treatment. Combined vascular bypass is currently the most effective surgery for the treatment of smog, after being introduced into China, combined vascular bypass has been improved and enhanced to maximize the recovery of patients, more smog patients therefore see the hope of treatment, according to statistics, at present, combined vascular bypass has treated more than a thousand patients, and after long-term follow-up found that patients in the post-operative recovery is basically good.
