title: Influencing factors for posttraumatic hydrocephalus in patients suffering from severe traumatic brain injuries.
abstract: OBJECTIVE
  To detect the influencing factors for posttraumatic hydrocephalus in patients with severe traumatic brain injuries and provide theoretical reference for clinical treatment.
  
  
  METHODS
  Retrospective study was made on 139 patients with severe traumatic brain injuries in our hospital. The patients were divided into two groups: hydrocephalus group and non-hydrocephalus group. Single factor analysis and multiple factor analysis were used to determine the related factors and hydrocephalus. Multiple factor analysis was conducted with logistic regression.
  
  
  RESULTS
  Posttraumatic hydrocephalus was found in 19.42% of patients. Age(OR equal to 1.050, 95%CI: 1.012-1.090), decompressive craniectomy (OR equal to 4.312, 95%CI: 1.127-16.503), subarachnoid hemorrhage(OR equal to 43.421, 95%CI: 7.835-240.652) and continuous lumbar drainage of cerebrospinal fluid (OR equal to 0.045, 95%CI: 0.011-0.175) were screened out from nine factors as the influencing factors for posttraumatic hydrocephalus.
  
  
  CONCLUSIONS
  Risk factors for PTH are as follows: age, decompressive craniectomy and subarachnoid hemorrhage (SAH). Continuous lumbar drainage of cerebrospinal fluid can greatly reduce posttraumatic hydrocephalus.
