Introduction: Practice guidelines for adult BCVI patients have been implemented recently, but data for this devastating injury pattern in children are still limited. An international multicenter analysis was performed to characterize BCVI in the pediatric population.
Methods: The TraumaRegister DGU®, a prospectively maintained database, was analyzed (01/2002-12/2015). Pediatric patients (0-17 years) with major injuries [Injury Severity Score (ISS) ≥ 9 points] were included. BCVI was divided into carotid artery injury and vertebral artery injury (VAI). Data of demographics, injury, imaging, therapy, and outcome characteristics were analyzed with SPSS (Version 25, IBM Inc., Armonk, NY).
Results: The study cohort included 8128 pediatric trauma patients. We identified 48 BCVIs in 42 children, resulting in an overall prevalence of 0.5%. Carotid injuries were diagnosed more frequently (n = 30; 0.4%) when compared to VAIs (n = 12; 0.1%). The coincidence of head (p = 0.028), facial (p ≤ 0.001), chest (p ≤ 0.001), and spinal injuries (p ≤ 0.001) was higher in BCVI patients. The risk for thromboembolic complications (8.3% vs. 1%, p = 0.026) and in-hospital mortality (38.1% vs. 7.7%, p ≤ 0.001) was excessive in children with BCVI. We identified various predictors for pediatric BCVI and quantified the cumulative impact of these risk factors.
Conclusion: BCVI is more uncommon in pediatric than in adult trauma patients. Due to the considerable relevance of this injury for both children and adults, special attention should be paid to this entity and associated complications in the early treatment phase after severe pediatric trauma, especially in high-risk children.
