title: [Analysis of prognostic factors for patients with traumatic acute subdural hematomas treated by surgery].
abstract: OBJECTIVE
  To analyze the factors correlated with the surgical prognosis of patients with traumatic acute subdural hematoma (ASDH).
  
  
  METHODS
  A total of 117 surgical patients for traumatic ASDH between January 2007 and August 2012 were retrospectively reviewed. The clinical factors correlated with prognosis were statistically analyzed.Glasgow outcome score (GOS) was used for prognostic evaluations and favorable prognosis was defined as 4-5 points.
  
  
  RESULTS
  The percentage of patients with favorable prognosis was 43.59% and the mortality 39.32%. The factors correlated with favorable prognosis included age <40 years, pre-operative GCS >8, no pre-operative herniation, duration between injury and surgical depression ≤ 4 h, without injury of drainage vein, mild brain edema and good brain palpation; the factors correlated with mortality included age >60 years, pre-operative GCS ≤ 8, pre-operative herniation, duration between injury and surgical depression >4 h, injury of drainage vein, serious brain edema and weak brain palpation Logistic regression confirmed preoperative GCS >8, no preoperative herniation, injury of drainage vein and postoperative good brain palpation were independent factors associated with favorable prognosis.
  
  
  CONCLUSIONS
  Patients with age <40 years, preoperative GCS>8, no preoperative herniation, injury of drainage vein and postoperative good brain palpation tend to have favorable prognoses.
