title: Severe traumatic brain injury in Austria V: CT findings and surgical management.
abstract: OBJECTIVE
  The aim of this paper is to describe CT findings and surgical management of patients with severe traumatic brain injury (TBI) in Austria.
  
  
  METHODS
  Data sets from 415 patients treated by 5 Austrian hospitals were available. The analysis focused on incidence, surgical management, and outcome of different types of intracranial lesions, and outcome of surgical interventions with and without monitoring of intracranial pressure (ICP). For the first analysis we assigned the patients to 16 groups based on the type of lesion as evaluated by CT scan. For the second analysis we created 4 groups based on surgical treatment (yes/no) and ICP monitoring (yes/no).
  
  
  RESULTS
  The mean age was 48.9 years with a male to female ratio of 299:116. The most frequent single lesions were contusions (CONT) and diffuse brain edema. Combined lesions were far more common than single lesions; the most frequently observed combinations included CONT and subarachnoid hemorrhage (SAH) with or without subdural hematoma (SDH). Surgery was done in 276 (66.5%) patients. Osteoplastic surgery (OPS; n = 221) was the most common method followed by osteoclastic surgery (OCS; n = 91) and decompressive craniectomy (DEC; n = 15). ICU mortality was 29.7% for all patients who had any kind of surgery, which was lower than that of patients who were treated non-operatively (33.1%). The ICU mortality of patients with SDH was lower with OCS (18.8%) than with OPS (36.0%). Patients who received ICP monitoring but did not require surgery had the lowest 90 day mortality (17.5%).
  
  
  CONCLUSIONS
  ICP monitoring seems to be beneficial in both operatively and non-operatively treated patients with severe TBI. Patients with SDH who were operated on had significantly better outcomes. In patients with SDH, their outcome after osteoclastic surgery was significantly better than after osteoplastic procedures.
