The first time I saw a woman, I thought I was pregnant, but I found an intracranial hemorrhage. I was dizzy, nauseous and vomiting for a week. However, when Wu Xiaoli looked at the “not pregnant” test stick with disappointment, the headache and nausea struck again. What’s wrong with the continuous nausea? In Hangzhou First People’s Hospital, Wu Xiaoli found the answer from the cranial CT: smog disease. 30-year-old young woman suffering from “smoke disease” 30-year-old Wu Xiaoli from Guizhou, working in Hangzhou. Recently, Wu Xiaoli had frequent headaches and vomiting, and after finding out that her symptoms were not caused by pregnancy, she rushed to the hospital. The cranial CT showed that there was blood accumulation in Wu Xiaoli’s brain, but Dr. Wang Hao, deputy chief of neurosurgery, took a medical history and found that Wu Xiaoli had frequent headaches, dizziness, and several unexplained episodes of limb weakness, and concluded that this was not a simple brain hemorrhage. In order to further determine the cause of the brain hemorrhage, Wu Xiaoli underwent cerebral angiography – it turned out that Wu Xiaoli had “smoke disease”. Through the analysis of her condition, the entire neurosurgery department carefully discussed the surgical plan. After the surgery, Wu Xiaoli recovered well, and a repeat angiogram revealed that the bypass vessel was very smooth and the original symptoms were cleared. Smoke disease is like a “drought and flood” in the brain “The exact cause of smoke disease is still unclear, it is a chronic progressive cerebrovascular occlusive disease of unknown cause.” Wang Hao said, “Let’s say that the neurons in our brain, which are in charge of various functions, are like crops planted in the ground, the glial tissue is like the soil, and the cerebral blood vessels are like irrigation channels.” Under normal circumstances, the brain is like the land, well irrigated, and the crops grow lush. If the irrigation channels are gradually blocked, it will cause drought. Similarly, the brain is “drought”. That is, the brain in the ischemia, and in severe cases, even cerebral infarction. This is the process of smog causing cerebral ischemia and cerebral infarction. ”But our brain is very ‘smart’, the main channel is blocked, will automatically open some small ‘sub-channel’ to alleviate its downstream ‘drought as much as possible These side channels are the smoke-like vessels we see in angiography, which is where the name of the disease comes from.” Wang Hao said humorously, but these smoke-like vessels are not original after all, its walls are very thin, easy to rupture and bleed, and once ruptured and bleeding, it can cause ‘flooding’ in the brain, which can drown crops and affect neurological function just as well. So smog can cause both cerebral ischemia (drought) and cerebral hemorrhage (flooding). Poor memory performance alerted to smog In China, smog is most common in people aged 10-14 and around 40 years old, and is significantly more common in adults than in children. Patients may experience symptoms of cerebral ischemia such as dizziness, dizziness, limb weakness, speech impairment, or cerebral hemorrhage due to rupture of smoke vessels. ”Defects in early cerebrovascular development are easily exposed during adolescence and middle age, which is why patients with smog disease are mostly concentrated in these two age groups.” Wang Hao said that affected children often faint due to crying or excitement, or have a significant drop in academic performance or reduced movement of one limb. Adult patients may experience increased dizziness or limb weakness while playing a musical instrument, or unconsciously experience significant memory and calculation loss. Surgical procedures are currently the primary treatment for smoker’s disease. After the blood supply to the brain improves, the need for smoky blood vessels will gradually diminish, and indirectly, the probability of brain hemorrhage is reduced. For those crops that have withered, they can usually be restored to life by improving irrigation. Crops that have already died, even if irrigation is restored, will not help. However, improved irrigation can reduce the risk of other crops dying again.
