Identifying predictors for blunt cerebrovascular injuries (BCVI) is crucial for effective screening. High-risk factors like low Glasgow Coma Score or specific fractures can help focus resources on patients most likely to have BCVI.

Area of Science:

  • Trauma Surgery
  • Vascular Surgery
  • Neurology

Background:

  • Early diagnosis and intervention improve outcomes for blunt cerebrovascular injuries (BCVI).
  • Aggressive screening for BCVI has led to an increase in identified cases, posing a resource dilemma.
  • Identifying independent predictors of BCVI is necessary to optimize screening efforts.

Purpose of the Study:

  • To identify independent predictors of blunt cerebrovascular injuries (BCVI).
  • To guide resource allocation for BCVI screening in trauma patients.

Main Methods:

  • Cerebral arteriography was performed for suspected BCVI based on symptoms or high-risk mechanisms/injury patterns in asymptomatic patients.
  • Logistic regression analysis was used to determine independent predictors of BCVI.

Main Results:

  • Of 249 patients who underwent arteriography, 85 (34%) had BCVI.
  • Independent predictors for carotid arterial injury included Glasgow Coma Score ≤6, petrous bone fracture, diffuse axonal brain injury, and LeFort II or III fracture.
  • Patients with at least one high-risk predictor and a high-risk mechanism had a 41% risk of injury; 39% of patients with cervical spine fracture had vertebral arterial injury.

Conclusions:

  • Screening for BCVI is recommended for patients with high-risk injury mechanisms or patterns.
  • Limited resources necessitate focusing screening efforts on patients identified with high-risk predictors of BCVI.
