Smoke disease is not literally a lung disease related to smoking, but a very rare cerebrovascular occlusive disease, precisely because the shape of the blood vessels presented in the cerebral angiogram resembles the curl of smoke and so named, this rare disease first appeared in Japan, is now also concentrated in the Asian region onset, Europe and the United States is relatively rare. The treatment of smog has been explored by medical doctors since the moment it was discovered, and it is now accepted that medication is not very effective in treating smog, and can only provide temporary relief but not long-term treatment. The only way to treat smog is through surgery. At present, there are two main types of traditional surgery for smog in China, direct bypass surgery and patching surgery, but in the long-term postoperative follow-up, it was found that both types of surgery have their own disadvantages. During this period, there is still a risk of ischemia. Some hospitals use combined vascular bypass surgery for the treatment of smog, which is a combination of two traditional surgeries with better results than they could achieve alone. This procedure has saved more than a thousand cases of families who were helpless in the face of smog since it was first performed, and has allowed smog patients to slowly return to a normal life.
