Summary

Establishing factors affecting outcomes in severe diffuse brain injury (SDBI) is challenging. Early clinical evaluation, CT scans, and intracranial pressure (ICP) monitoring significantly correlate with patient outcomes.

Area of Science:

  • Neurology
  • Neurosurgery
  • Trauma Care

Background:

  • Severe diffuse brain injury (SDBI) presents diagnostic challenges due to a lack of specific clinical signs.
  • Determining factors influencing patient outcomes is crucial for effective clinical management.

Purpose of the Study:

  • To retrospectively analyze epidemiological, clinical, and radiological factors associated with the final outcomes of patients with SDBI.
  • To identify key predictors of patient outcomes in severe diffuse brain injury.

Main Methods:

  • Retrospective study of 160 consecutive patients diagnosed with SDBI.
  • Statistical analysis of demographic, clinical, and radiological data, including Glasgow Coma Scale (GCS), CT findings, and intracranial pressure (ICP).
  • Correlation of these factors with outcomes assessed using the Glasgow Outcome Scale (GOS).

Main Results:

  • SDBI was present in 35% of severe head injury patients, predominantly affecting young males (15-35 years old).
  • High rates of low GCS scores (3-4), white matter lesions, subarachnoid hemorrhage, and elevated ICP (>20 mm Hg) were observed.
  • Mortality exceeded 50%, with 25% experiencing persistent vegetative states or severe disability.

Conclusions:

  • Clinical assessment, early CT scan results, and ICP values, along with their response to treatment, are significantly related to the final patient outcome (GOS).
  • These factors are critical for predicting prognosis in SDBI patients.
