After intracranial hematoma removal, there will be more or less sequelae, commonly headache, dizziness, nausea and other symptoms. In patients with epidural hematoma, the sequelae are relatively mild because they occur in the epidural and the amount of bleeding is relatively small, while the sequelae of subdural and intracerebral hematoma are relatively severe. In addition, the size of sequelae is determined by the site of bleeding, the amount of bleeding, and the patient’s own conditions. Hemiparesis, aphasia, seizures, mental disorders, hydrocephalus, are all sequelae of focal neurological injury, and in severe cases, coma for more than six months, i.e., vegetative state.
