Smoker’s disease is a rare cerebrovascular disease that was first identified and named by Japanese scholars in the 1950s and 1960s. It is mainly a chronic progressive narrowing or occlusion of arterial vessels in the brain, which then leads to compensatory dilation of the vascular network at the base of the skull, forming slender and fragile smoke-like vessels. Smoldering disease is very dangerous, prone to cerebral ischemia, cerebral infarction, cerebral hemorrhage, and even life-threatening in severe cases. For example, if a large amount of cerebral hemorrhage occurs and is not disposed of in time, it may kill you directly. The onset of smoker’s disease, i.e. cerebral infarction and cerebral hemorrhage, is often without signs and symptoms, so it is possible that the infarction or hemorrhage may occur suddenly, catching people off guard. Therefore, once smoker’s disease is detected, surgery should be performed as soon as possible if the diagnosis is clear. Because of the narrowing of blood vessels, some people ask about interventional treatment for smog. In some cases, the blood vessels cannot be effectively dilated during treatment, which may even lead to destructive intracerebral hemorrhage. Our combined vascular bypass surgery is a more advanced and effective way of treating smog. The combination of direct bypass and patching allows for the creation of a complete blood bypass to provide adequate blood supply to the brain.
