Does volume of extradural hematoma influence management strategy and outcome?

AIMS: To evaluate the management strategy of extradural hematomas (EDH), particularly with respect to its volume.
METHODS AND MATERIALS: Two hundred and three patients with EDH and no other significant intracranial injuries were treated over a period of three years.
RESULTS: The factors influencing management strategy and outcome were the Glasgow coma scale (GCS), volume of extradural hematoma (EDHV) and its location. The ultimate clinical outcome was significantly better in patients having EDHV of less than 30 ml.
CONCLUSIONS: The key factors influencing the management strategy and clinical outcome are EDHV and GCS at the time of admission. A patient with EDH should not be considered for conservative management if EDHV is more than 30 ml and GCS is 13 or less.
