title: [Extradural hematoma: comparative radiological study between comatose and non-comatose patients].
abstract: A series of 129 patients harbouring extradural hematomas was analysed considering the neurological state immediately before operation as the most consistent variable. Seventy eight patients were considered to be comatose (Group I) and 51 were noncomatose. Among the comatose group, 30 were investigated with computerized tomography (23.3% mortality, 50% good results), 31 were submitted to angiography (48.3% mortality, 38.7% good results), and 17 were operated based on the neurological examination and skull radiography (47% mortality, 35.2% good results). The presence or absence of skull fracture and the density of hematoma did not change the final outcome. Associated intracranial lesions increased the mortality and lowered the good results in both groups. Frontal hematomas (10 cases) in the comatose group were associated with high mortality (52.6%) due to bad neurological state (Glasgow 3-5) and to isolated or multiple intracranial associated lesions (6 patients).
