Many children may run and run out of energy during physical education class. When they cry, they cry and jerk over. There are even some children who suddenly have seizures. There are also some children, his body is always involuntarily shaking …… such children, in general, parents do not know what the cause, to the hospital to check, a check may be found to be smog. This is exactly what the initial onset of smog in children looks like. Adults with smog may also have cerebral infarction and cerebral hemorrhage. Because the blood vessels in the brain become narrowed and blocked, ischemia can cause a lack of blood supply to the brain, resulting in headaches and dizziness; if the long-term lack of blood supply to the brain leads to a decline in brain function, cognitive decline, and gradual loss of memory; or transient cerebral ischemia, where the patient suddenly becomes unable to speak, has weakness in one limb, hemiparesis, aphasia, or hydrocephalus. Many people may not have heard of smog, but the damage caused by untimely treatment of smog patients is very obvious. Therefore, when any of the above-mentioned symptoms appear at the initial stage, patients should go to a regular hospital for diagnosis and treatment in a timely manner, and cooperate with professional doctors for treatment. Combined vascular bypass surgery is a composite procedure of direct bypass + patching, where both procedures are done on one surgery. The bypass is to anastomose the superficial temporal artery with the middle cerebral artery to rapidly establish the blood flow side branch channel to improve the local blood supply to the brain, and at the same time, the multi-factor of brain-dural-temporal muscle-artery-cranial periosteum is applied to induce the formation of neovascularization in a larger area to improve the blood supply to the brain in a larger area and improve the surgical effect.
