title: [Incidence and treatment of subdural hygroma in severe head injuries].
abstract: In a population of 109 subjects with severe head injury (Liège score less than or equal to 12) we observed secondary development of subdural hygroma in sixteen patients. These liquefying processes were mostly secondary to the entry of CSF in the subdural space from tears in the arachnoid. Half the accumulations were accompanied by increased subdural pressure. Drainage of the subdural fluid brought clinical improvement in patients with elevated subdural pressure (greater than 15 torr).
