When it comes to smoker’s disease, many people would think that it is some kind of disease within the organs caused by excessive smoking. In fact, it is a chronic progressive cerebrovascular occlusive disease of unknown origin, which was discovered in Japan in 1961. The disease was discovered in Japan in 1961. It was named smoker’s disease because cerebral angiography showed abnormal tiny blood vessels resembling smoke. As a rare cerebrovascular disease, the treatment of smog disease has always been a mystery to medical experts from different countries. At present, the medical profession recognizes that the symptoms of smog can be relieved initially by symptomatic treatment with internal medicine, but the effect will be greatly reduced in the long term. Therefore, once the diagnosis of smog is confirmed, surgery should be performed as soon as possible. It is important to improve the blood supply to the brain and prevent ischemic damage before irreversible brain tissue dysfunction occurs. For the current surgical treatment of smog, the two traditional surgical approaches in China are direct bypass surgery and patching. However, each of these two methods has its own drawbacks and limitations. Direct bypass can improve the local blood supply in a short period of time and reduce the occurrence of ischemic stroke, but the surgery is difficult and the scope of blood supply improvement is limited; while patching can induce the formation of neovascularization, but the formation of blood vessels requires a certain period of time, during which there is still a risk of ischemia. In order to let the majority of smog patients recover as soon as possible, direct bypass and patching are performed at the same time, in one operation, to immediately improve the blood supply to the brain and at the same time induce the formation of new blood vessels through multi-factor patching.
