Smoker’s disease was first discovered by Japanese specialists as a result of chronic progressive stenosis or occlusion of the ends of the internal carotid arteries, resulting in inadequate blood supply to the brain, followed by the formation of small capillaries at the base of the skull that look like smoke, hence the name smoker’s disease. Although rare, smog, a disease whose cause is still unknown, has a significant population with peak incidence in children under 10 years of age and adults over 40 years of age. Currently, smog has been classified as a major disease that poses a serious threat to human health. Although smog is a rare cerebrovascular disease, its incidence has gradually increased in recent years in China. In addition to sudden weakness of the extremities, patients with smog disease may also experience other symptoms. For example, dizziness, headache, episodic aphasia, loss of intelligence or memory, cerebral infarction, cerebral hemorrhage, etc. Timely detection and prompt treatment are very important for patients with smog and can prevent dangerous situations from occurring. Scientific treatment methods for smog is a major achievement in the medical field. Studies have found that drug therapy can only be applied to improve short-term mild symptoms and has little effect on severe conditions. In addition, long-term use of anti-platelet aggregation drugs may lead to the conversion of ischemic type to hemorrhagic type, which is not easy to stop once bleeding occurs and is not good for the patient’s prognosis. Combined vascular bypass is a recognized standard procedure for the treatment of smog, which can establish a perfect blood supply system for the brain and improve brain blood supply, and can effectively solve the problem of ischemic stroke and brain hemorrhage.
