As a rare disease, it is normal that many people have never heard of it, and it is easy to misunderstand from its name alone. In fact, it is a cerebrovascular disease, which is caused by the narrowing or occlusion of the main branches of the cerebral artery ring, resulting in abnormalities in the vascular network at the base of the skull, and the formation of many small blood vessels resembling smoke, which are very fragile and at risk of cerebral infarction and cerebral hemorrhage if not controlled by timely treatment. In clinical practice, a large proportion of patients with smoky disease have headache and dizziness, and some patients have seizures, and smoky disease can lead to cerebral ischemia and cerebral hemorrhage. Smog is extremely dangerous, so once it is diagnosed, it must be treated actively. However, smog is an occlusive cerebrovascular disease, and it is difficult to improve and solve the problem of narrowed or occluded blood vessels in the brain with drugs. Can smog be cured by surgery or not? Traditional surgical methods include direct bypass and patching, except that these two methods are still somewhat single in treatment, and sometimes the post-operative recovery effect is not very satisfactory. The combined vascular bypass surgery carried out by the team of Director Jin Yongjian of the Department of Neurosurgery for Cerebrovascular Diseases of the General Hospital of Aviation of China Medical University combines the advantages of the two previous surgeries and avoids their respective shortcomings, so that the treatment is more comprehensive and not only can induce the formation of neovascularization in a larger area, but also can really play a role in improving the blood supply to the brain and has achieved good clinical results.
