The new tiny blood vessels in the skull cause the brain to “fog up” not only affects intellectual development, but also causes cerebral infarction and bleeding Shan Shan (a pseudonym), a 12-year-old girl from Lishui, Zhejiang Province, has been screaming about headaches for six years until she collapsed during a gym class run last year, when her family sent her to the hospital for treatment and the doctor told them a strange name: smog. Wang Lin, deputy director of neurosurgery at the Second Hospital of Zhejiang University School of Medicine, introduced smog disease as a result of narrowing or occlusion of cerebral blood vessels resulting in insufficient blood supply to the brain. In this slow process, because the brain blood supply needs, so the cranium is constantly new many tiny blood vessels to participate in the brain blood supply. As a result, the cerebral angiogram will appear like the smoke exhaled when smoking, and the name “smoke disease” is derived from this. The 12-year-old girl suffered from the disease for 6 years. It is understood that Shan got the smoke disease when she was 6 years old, but at first she just often cried out for a headache, and the root cause of the headache was not examined at that time due to the family’s condition. After she started elementary school, her family noticed that Shan’s academic performance gradually failed to keep up with other students in her class. In the summer of 2013, Shan went to the neurosurgery department of Zhejiang Medical Second Hospital for further treatment. Wang Lin still remembers the first time he saw Shan, not only was she timid compared to her peers, but her intelligence was also really low. “This is a typical smoker’s disease, which affects the child’s brain function and intelligence. Perhaps the disease has brought Shan a lot of pain, but she is still a child favored by fate. Wang Lin said all the doctors and nurses as well as Shanshan’s parents could clearly feel that Shanshan’s whole condition had improved after the surgery, and she gradually became cheerful and active. “Although the damage caused to Shanshan by her condition over the years cannot be completely undone, and the improvement in intelligence may not be reflected in a short period of time, this is already a great improvement.” Wang Lin feels relieved. The disease has a distinctly regional nature. People may find it strange to hear the term “smog”, but it was Japan that first introduced the concept of this disease. Wang Lin introduced, smoke disease in the distribution of the typical regional, mostly in East Asian countries, Japan is the world’s highest incidence of countries, followed by China and South Korea, Japan’s 1/3, while Europe and the United States is only Japan’s 1/10. In China, the disease also shows the same regional. Zhejiang, Henan and Anhui provinces are among the most prevalent provinces, and Zhuji is the most prevalent city in Zhejiang Province. The age of high incidence is 8-12 years for children and 45-50 years for adults. The incidence is higher in women. There is no definite conclusion in the medical community as to the reasons for the typical geographic distribution and male/female incidence ratio, and some researchers speculate that there is a relationship with ethnicity and family genetics. Thankfully, however, smog is not contagious. Because smog is an insidious disease, most people do not perceive their condition when it does not develop in the early stages. Hemorrhage and infarcts are the most common clinical findings. If the microscopic vessels are in a functional area, then the corresponding function is affected, with the most immediate result being hemiplegia. In terms of examination, it is difficult to get results from general blood tests because there is basically no warning when the disease is not present. Currently, digital subtraction angiography (DSA) is still the most accurate and reliable diagnostic method, and magnetic resonance imaging/magnetic resonance angiography (MRI/MRA) can make a definitive diagnosis for most patients with smog. Reminder Surgical treatment is an option for those with the condition Treatment of smog is generally divided into two categories: medical treatment and surgical treatment. Surgical procedures are performed to address the blood supply to the brain by performing a “bypass” of the brain, forming a vascular bridge that connects the blood vessels in the neck to the blood vessels in the brain, bringing blood flow from outside the skull directly into the skull. Since many people are reluctant to undergo cranial surgery, they opt for medical treatment. Internal treatment is symptomatic treatment by thrombus, i.e., cerebral infarction – lowering cranial pressure, stopping bleeding, and decreasing edema. ”Once smog is detected, it’s best to treat it aggressively and undergo surgery if you have the conditions.” Wang Lin said relevant statistics show that patients who do not have surgery will have serious complications in 2/3 of them in the following years to a dozen years, while the serious complications of surgery are actually less than 5%, so it is still worth taking the risk.
