Smoker’s disease was first identified by the Japanese, and was first reported by a Japanese academic in the 1950s and 1960s. It is a rare cerebrovascular disease in which progressive narrowing or occlusion of the major arteries of the brain subsequently causes smoke-like changes in the vascular network at the base of the skull. This disease is prone to cerebral ischemia and cerebral hemorrhage. Patients with smog disease should pay attention to their diet in daily life, what to eat and what not to eat in smog disease is good, this should be done in mind. In general, it is recommended that smog patients consume more fresh vegetables and fruits, use more vitamin-rich foods, and also consume more protein-rich foods, such as milk and egg whites. It is worth noting that egg yolks should not be eaten too much, because the lipids rich in egg yolks may have some effect on the blood vessels of smog patients if they eat too much. Smoke patients should eat less cold drinks or do not eat cold drinks, eat less sweets, avoid eating spicy and stimulating food, eat less meat, and avoid eating large fish and meat, overeating. Of course, a reasonable diet is only a small aspect, but the most important thing for patients with smog is early detection and early treatment. Once smog is detected and clearly diagnosed, surgery should be performed as soon as possible. First of all, smog is a chronic progressive disease, which will gradually develop and worsen and become more and more serious, so it must be treated as early as possible to prevent irreversible damage caused by cerebral ischemia or cerebral hemorrhage; in addition, conservative medical treatment for smog is useless, no matter what drugs are used, it is impossible to change its vascular malformation, so the medical profession recognizes that smog must be treated surgically. At present, we use combined vascular bypass surgery for the treatment of smog to re-establish blood bypass channels for patients to improve the blood supply to the brain. Combined vascular bypass surgery is a combination of direct vascular bypass and patching, in which the superficial temporal artery is bypassed to the middle cerebral artery and tissues with vascular regeneration ability (such as cranial periosteum, middle meningeal artery, temporalis muscle, dura mater, etc.) are selected for patching to the brain surface to promote the formation of new blood vessels and expand the blood supply. This surgical procedure has absolute benefits for treating smog and improving cerebral blood supply.
