    Abstract:
    INTRODUCTION: Angiography has been widely accepted as an adjunct in the management of blunt abdominal trauma in adults. However, the role of angiography with or without angioembolization (AE) is still being defined in pediatric solid organ injury. We sought to compare the use of angiography in solid organ injury (SOI) at pediatric trauma centers (PTCs) versus an adult trauma center (ATC) in a large metropolitan city. METHODS: Data were drawn from a collaborative effort of three Trauma centers (one adult and two pediatric) in Atlanta, GA. All pediatric patients (ages 1-18) treated for SOI between January 1, 2016 and December 31, 2021 were included (n = 350). Registry data obtained included demographics, mechanism of injury, injury grade, injury severity score (ISS), procedures performed, and transfusions. Multivariate regression analysis was used to identify factors associated with angiography. RESULTS: A total of 350 patients were identified during the study period with 101 treated at ATC and 249 treated at the two PTCs. The median age at the ATC was 17 y (IQR 16, 18) compared to nine (6, 13) at the PTCs. ISS was significantly higher at the ATC 22 (14, 34) compared to 16 (9, 22) at PTCs (P < 0.001). At the ATC, 11 (10.9%) patients underwent angiography, 4 (4.9%) of which underwent AE compared to seven (2.8%) patients who underwent angiography and AE at PTCs. In the multivariate analysis, factors associated with angiography use included age (OR 1.44, 95% CI 1.09-1.90, P = 0.010) and ISS (OR 1.05, 95% CI 1.02-1.09, P = 0.004). Through setting, ATC versus PTC was significant on univariable analysis, it did not remain a significant predictor of angiography on multivariable regression. CONCLUSIONS: Our study demonstrated increased utilization of angiography for the management of SOI in pediatric patients treated at ATCs versus PTCs. On regression analysis, age and ISS remained significant predictors for angiography utilization, while setting (ATC versus PTC) was notably not a significant predictor. This data would suggest that differences in angiography utilization for pediatric SOI at PTCs and ATCs are influenced by differing patient populations (older and higher ISS), with otherwise uniform use. These findings provide a basis for future treatment algorithm revisions for pediatric blunt abdominal trauma that include angiography and provide support for the development of formal guidelines.
