The brain is an advanced neurocentral system, the brain needs fresh blood injection every moment so that the cranial life activities can operate normally, but when suffering from certain diseases, the brain blood supply channel is blocked, the brain is severely ischemic, then it will cause more health problems. For example, if smog occurs, it sounds like a significant problem. When the blood supply channels to the brain are abnormally altered, the blood supply to the brain becomes abnormal, and the patient experiences various uncomfortable symptoms of ischemia such as headache, dizziness, numbness and weakness of the limbs. Smoker’s disease is a special form of cerebrovascular malformation, which is also known as cerebral base abnormal vascular network disease, after the disease, the blood supply to the brain is changed, and untimely treatment will lead to greater danger. In clinical practice, there are two types of smoker’s disease: ischemic smoker’s disease and hemorrhagic smoker’s disease, of which the onset of hemorrhagic smoker’s disease is more acute, and if the sudden brain hemorrhage is not controlled in time, the patient’s life is likely to be in danger. Therefore, once a brain hemorrhage from smog occurs, timely surgery is needed to control the hemorrhage and save the patient’s life. Is smoldering brain hemorrhage very serious? If the brain hemorrhage is serious, craniotomy may be required to open the patient’s bone flap and remove the hematoma from the skull. However, there is a point that there may still be a possibility of rebleeding after brain hemorrhage in smog disease, so it is recommended that patients should treat smog disease through surgery about 3-6 months after controlling brain hemorrhage.
