Metadata about: PURPOSE: Abusive head trauma (AHT) is the leading cause of fatal head injuries for children under 2 years. The objective was to evaluate, using transcranial Doppler ultrasound (TCD), whether children with AHT have a similar neurovascular response to injury compared with children without AHT. METHODS: Retrospective sub-analysis of previously prospectively acquired data in a pediatric intensive care unit in a level 1 trauma hospital. TCD was performed daily until hospital day 8, discharge, or death. Neurologic outcome was assessed using the Glasgow Outcome Scale Extended (GOS-E Peds) at 1 month from initial injury. RESULTS: Sixty-nine children aged 1 day to 17 years with moderate-to-severe traumatic brain injury were enrolled. Fifteen children suffered AHT and 54 had no suspicion for AHT. Fifteen children with AHT underwent 80 serial TCD examinations; 54 children without AHT underwent 308 exams. After standardization for age and gender normative values, there was no statistically significant difference in mean cerebral blood flow velocity of the middle cerebral artery (V(MCA)) between children with and without AHT. There was no difference in the incidence of extreme cerebral blood flow velocity (CBFV, greater or less than 2 standard deviations from normative value) between groups. Within the AHT group, there were no statistically significant differences in V(MCA) between children with a favorable (GOS-E Peds 1–4) versus unfavorable neurologic outcome (GOS-E Peds 5–8). CONCLUSION: Children with AHT have no significant differences in V(MCA) or percentage of extreme CBFV in the middle cerebral artery compared to with those without AHT.
