Birth, old age, sickness and death are necessary in everyone’s life, and this is a natural law that we should actively deal with and face. However, there are some diseases that are difficult to accept, especially some rare diseases. For example, a Mr. Zhao from Hubei said that he was feeling dizzy and unresponsive the other day, and when he went to the hospital for a checkup that it was a smog, he was a bit confused and didn’t know what kind of disease it was. Especially when the doctor told him to go to Beijing for surgery, he was even more drummed up in his mind. “Do I have to have surgery? Will smog disease be treated conservatively?” Smoker’s disease is a cerebrovascular disease, which is due to chronic progressive narrowing or occlusion of the siphon segment of the internal carotid artery, the anterior cerebral artery, the middle cerebral artery and sometimes the beginning of the posterior cerebral artery in the skull, followed by abnormal changes in the vascular network at the base of the brain, which is, to put it bluntly, a specific cerebrovascular malformation. It is unlikely that medication or other conservative means can change or correct this vascular malformation. Therefore, it is generally accepted in the medical community that conservative therapy is of little significance in the treatment of smog, and it is generally effective in relieving symptoms only at the early stage of the disease process, but not at the later stage. Therefore, once the diagnosis of smog disease is confirmed, surgery should be performed as soon as possible to reconstruct good cerebral blood flow channels through cerebrovascular bypass and improve cerebral blood supply in order to cure smog disease. At present, the combined vascular bypass surgery carried out by Professor Jin Yongjian of the Department of Cerebrovascular Neurosurgery of the Aviation General Hospital is a very advanced surgical procedure for the treatment of smog, which has a great advantage compared with other traditional procedures. The combined vascular bypass surgery can improve the cerebral blood supply to a greater extent and achieve a more ideal treatment effect through direct bypass + multi-factor patching.
