Smoker’s disease is a disease of the abnormal vascular network at the base of the skull caused by stenosis or occlusion of the main arteries of the brain, resulting in impaired blood supply to the brain. He has two main hazards, one is the narrowing or occlusion of the main blood vessels, which causes insufficient blood supply to the brain and can cause cerebral ischemia, leading to a series of ischemic symptoms, and in serious cases, leading to cerebral infarction; the other aspect is the skull base abnormal vascular network, that is, the compensatory formation of small smoke-like vessels, which have very thin and fragile walls and can rupture at any time leading to cerebral hemorrhage, leading to serious consequences, and sometimes It may even be life-threatening. Based on these two main hazards, smog is divided into two categories, ischemic smog and hemorrhagic smog. Some people ask how much ischemic smog treatment costs, but in fact, whether it is ischemic smog or hemorrhagic smog, the treatment is the same and the costs required are largely comparable. If there is a small difference, it is in the treatment of the acute phase. For ischemic smog, if it is only chronic ischemia with less pronounced symptoms, surgery can be performed immediately; while if it has triggered a cerebral infarction, it requires about two weeks of symptomatic treatment to recover before performing smog surgery; while for hemorrhagic smog, smog surgery should be performed after 3 months of the acute phase. Combined vascular bypass surgery is currently the more advanced and effective surgical procedure for smog. It is a compound surgery, where direct vascular bypass and patching are done in the same surgery, which can double-prongedly establish a more perfect blood supply bypass channel for the brain, improve the brain blood supply more effectively, and prevent the occurrence of cerebral ischemia, cerebral infarction and cerebral hemorrhage with absolute benefits.
