Chronic subdural hematoma in children

Subdural hematoma refers to subdural hemorrhage caused by trauma or coagulation dysfunction. The accumulation of blood in the space between the arachnoid and the dura mater results in brain injury. According to the appearance of clinical symptoms, they are divided into acute, subacute and chronic subdural hematomas. Chronic subdural hematoma refers to a hematoma that has developed symptoms more than 3 weeks after a head injury. Most hematomas result from minor neglected head injuries, which are often caused by birth injuries in children. Chronic subdural hematomas in children are mostly bilateral, and the bleeding mostly comes from the rupture of the bridge vein that joins the superior sagittal sinus on the surface of the brain. The bleeding pressure is low and the hematoma formation is slow, which usually does not cause a rapid increase in intracranial pressure.
