As the saying goes, there is no such thing as a disease, which reflects the desire for good health. Indeed, disease can be very devastating, especially some of the less common diseases that can be difficult to treat. Smoke disease, for example, is a relatively rare cerebrovascular disease, and many people have never even heard of it. Smoke disease was first discovered by Japanese medical experts in the 1950s and 1960s, because when a cerebral angiogram was done, the vascular network at the base of the skull was imaged like the smoke exhaled when smoking, so it was imaginatively called smoke disease by the Japanese. It is a chronic progressive stenosis or occlusion of the main branches of the cerebral arterial ring bilaterally, resulting in compensatory hyperplasia of the penetrating arteries at the base of the skull, resulting in the formation of small, fragile smoky vessels. Smoke disease can easily lead to cerebral ischemia, cerebral infarction, cerebral hemorrhage, seizures, etc. It is very dangerous, so once the disease is affected, it should be treated promptly. Some patients ask whether it is better to take medicine or surgery for smog. It does not exist whether it is good or not, because smog disease is necessary to be cured by surgery, drugs can not cure smog disease. The medical profession recognizes that medical treatment can only relieve the symptoms to a certain extent in the early stage, but the effect is not good in the later stage; once the diagnosis of smog disease is clear, surgery should be performed as soon as possible. At present, Professor Jin Yongjian’s team at Aviation General Hospital of China Medical University widely carries out combined vascular bypass surgery to treat smog, which has achieved very good clinical results. Prof. Jin introduced that the combined vascular bypass surgery is a composite procedure of direct vascular bypass + patching. While the direct bypass quickly solves the blood flow of the main blood vessels, multi-factor patching is applied to the brain surface to induce the formation of new capillaries, which can improve the brain blood supply in a larger area and achieve a more ideal treatment effect.
