Smoker’s disease is a relatively rare cerebrovascular disease, first seen in Japan, mostly in Asia, and also in other parts of the world. Smoky disease usually causes cerebral ischemia, cerebral infarction, and cerebral hemorrhage, and some patients, especially children, may present with seizures. The age distribution of smog shows certain characteristics, with a bimodal distribution, mainly in adults around forty years old and children under ten years old. In adults, both ischemic and hemorrhagic symptoms are present in equal proportions, while in children, except for a small number of patients with epilepsy, most of them have mainly ischemic symptoms, and hemorrhagic symptoms are very rare. In children with smog, the symptoms are usually a transient limb weakness, blindness, visual field loss, and speech impairment, especially when the child is crying or has a cold or fever, which can easily cause a brain ischemic attack. Smoke disease needs to be treated by surgery in time. What is the success rate of surgery for smog in children? Theoretically, children have more delicate blood vessels, so bypass surgery is more difficult. Many experts do not recommend surgery for children under the age of three. For example, a neurosurgeon in Beijing performed a successful combined vascular bypass surgery on a one-year-old smog patient from Heilongjiang. This was the youngest child in the world to undergo combined vascular bypass surgery for smog, which shows that young age is not a contraindication to smog surgery. The success rate of smog surgery in children is also very high in clinical practice.
