Abstract

Objective: To evaluate the correlation between transcranial Doppler (TCD) parameters and the Rotterdam score (RS) and to identify clinical and radiological factors associated with cerebral hemodynamic alterations in pediatric patients with traumatic brain injury (TBI).

Methods: An observational, prospective, correlational study was conducted in 30 patients with TBI. Data on age, Glasgow Coma Scale, and trauma severity (TS) were obtained from medical records. Hemodynamic measurements were performed using TCD within the first 48 hours after admission. Flow velocities of the middle cerebral artery and the internal carotid artery were recorded, along with the resistance index, pulsatility index, and Lindegaard index (LI), measured bilaterally. Spearman’s correlation analyses and multiple linear regression models were applied.

Results: The right LI showed the strongest positive correlation with the RS (ρ = 0.52, p = 0.002). The right LI was also the parameter most significantly associated with TS (p = 0.002). In multivariate analyses adjusted for age and sex, RS (β = 0.52, p = 0.045) and TS (β = 0.84, p = 0.012) showed significant and independent associations with the right LI.

Conclusions: The right LI was significantly associated with both the RS and TS in pediatric patients with TBI. This finding suggests that this TCD parameter may represent a potential hemodynamic marker in pediatric TBI.
