In recent years, the incidence of cerebrovascular disease is increasing, and many middle-aged and elderly people are unfortunately suffering from cerebrovascular disease as a result. But there is a cerebrovascular disease, medically called smog, which can affect not only adults over 40 years old, but also children under 10 years old. Xiao Yu, a one-year-old child with smog from Jilin, developed twitching at the corners of her mouth and unfavorable movement of her right limb 8 months after birth, and again at the age of one, when she went to the hospital for examination suggesting smog. She went to many hospitals around the country to seek treatment, but was rejected because the child was too young and the risks were too great. Later, she came to us for treatment, and after a joint consultation with experts, the combined vascular bypass surgery of Xiaoyu’s left and right sides of the brain was successfully completed in September 2018 and March 2019, respectively, with the multidisciplinary collaboration of neurosurgery, anesthesiology, pediatrics, nursing department, and medical department. After the surgery, Xiaoyu recovered well. Beijing TV has interviewed and reported on the two surgeries, and CCTV, Qilu.com and many other media have reproduced the reports. In life, many parents may think that a rare disease like smog should not happen to their children, so when their children have symptoms of weakness of limbs, dizziness and nausea, they tend to neglect them, thus delaying the treatment as well. It is recommended here that parents first need to have a detailed understanding of smog, such as its symptoms, hazards, treatment, etc., so that they can bring their children to receive better treatment in a timely manner after they become ill. Can cerebrovascular smog be cured? In the treatment of smog disease, local hospitals are not good at it, and most of them take conservative medication, which cannot cure smog disease, which leads many patients to seek treatment in different parts of the country. From the current treatment results, the better method is to do surgery. The current combined vascular bypass surgery is ideal for treating smog. This technique is a combination of direct bypass + patching, which achieves rapid improvement of cerebral blood supply while forming new blood vessels on a larger scale to further improve the surgical effect.
