Smoker’s disease was first discovered by Japanese medical experts in the 1950s and 1960s. On imaging, it appears as a narrowing or occlusion of the major arteries, and the vascular network at the base of the skull shows a cloud of small smoke-like vascular shadows, so the Japanese call this disease figuratively as smoker’s disease. Some experts and scholars have typed smog disease, and the types of smog disease are TIA, infarctive, hemorrhagic, and epileptic. Smoke disease tends to lead to cerebral ischemia, and a significant proportion of patients start with TIA attacks (transient ischemic attack), i.e., transient cerebral ischemic symptoms, which usually recover on their own; there is also a proportion or lead to cerebral infarction, dizziness and headache, limb weakness. Patients with hemorrhagic type are more dangerous, some patients have sudden onset of severe headache and even fainting, and intracranial hemorrhage may even be disabling and fatal if the amount is too large; there are also some patients who show seizures. Of course, regardless of the type of smog, it is important to seek medical attention as soon as possible. Surgery is currently the mainstay of treatment for smog, as it is generally accepted that conservative treatment is not very useful. Currently, combined vascular bypass surgery is a very advanced and effective surgical procedure for smog. This surgery can maximize the reconstruction of cerebral blood flow channels, improve cerebral blood supply, and effectively prevent cerebral ischemia and cerebral hemorrhage.
