Smoker’s disease, simply put, is a specific type of cerebrovascular malformation disease, mainly narrowed or occluded cerebral arteries, which obstructs the blood supply to the brain and creates a series of problems for a person’s health and safety. When there is a transient ischemia in the brain, people will gradually develop nausea and vomiting, memory loss, mental decline, and triggering cerebral infarction. In addition to this, brain hemorrhage can occur, which is often acute and sudden and may result in death due to untimely treatment. Smoker’s disease is a veritable rarity, and no precise answer has been found about its pathogenesis, even today when scientific research is so strong. Some claim that it may be caused by congenital genetic factors, while others claim that it may be a disease related to allergic cerebral vasculitis. Whichever the cause, there is no valid and reasonable evidence to date to explain it. This leaves medical researchers to further research and figure out the way forward. The medical treatment of smog is mainly based on vasodilators and anticoagulant drugs, which can make local improvement of the initial symptoms in the short term, but have little long-term effect. Currently, surgical treatment has become a prominent tool in the treatment of smog. Among the three surgical procedures, namely bypass surgery, patching and combined vascular bypass surgery, combined vascular bypass surgery has become the standard procedure for the treatment of smog due to its multifaceted and smooth blood flow channels and efficient improvement of cerebral ischemia.
