title: Double extradural hematoma: an analysis of 46 cases.
abstract: OBJECTIVE
  The authors analyze epidemiology, location, clinical profile and outcome of double extradural hematoma (EDH) or EDH at more than one site.
  
  
  METHODS
  A retrospective clinical study.
  
  
  METHODS
  46 cases of double EDH were studied. All the cases were evaluated for their mode of injury, clinical presentation, level of sensorium at the time of injury, CT scan finding and outcome after surgery, and were compared with single EDH cases.
  
  
  RESULTS
  Out of 1025 cases 46 cases had 'double' EDH. There was bilateral EDH in 39 cases; multiple EDH in 3 cases and ipsilateral double EDH was present in 4 cases. The most common site was frontal (70%). The majority of the patients (80.3%) were in altered sensorium from the time of injury, similar situation was seen in 52.2% of cases with single EDH. The number of patients having a low GCS score was higher when first examined in the double EDH group and the mortality rate was 34.8% as compared to 9% in the single EDH group.
  
  
  CONCLUSIONS
  Majority of the double EDH cases presented with a low GCS and there was a relatively quick neurological deterioration in these cases.
