Angiography and embolization are part of trauma management protocols for various injuries. This study examines the use of angiography and embolization use in trauma care across Trauma Centers in the United States.We used the National Trauma Data Bank (NTDB) 2017 dataset in this retrospective observational study. Adult trauma patients (≥16 years) who underwent conventional angiography with or without embolization were included. A univariate analysis was carried out to describe patients' demographic and injury characteristics as well as the time to angiography, angiography details, complications, and outcome (survival to hospital discharge: yes/no). One-year period prevalence proportion of angiography procedure was determined.A total of 4242 patients were included. The 1-year period prevalence proportion of angiography procedure with or without embolization was 0.53% (95% confidence intervals: 0.527-0.529). The median age was 41 years (interquartile range: 27-58) with most patients being in the age group 16 to 64 (83.8%) and males (72.6%). Over half of the patients, 55.4% had an embolization procedure performed in addition to angiography. The mean time to angiography was 263.77 ± 750.19 minutes. The most common embolization sites were the pelvis (24.9%), spleen (11.8%), and liver (9%).This study described angiography and embolization utilization in adult trauma patients in Trauma Centers in the US. Its findings provide the basis for future studies to examine more closely angiography/embolization utilization in specific subpopulations, and to create standardized risk stratification tools for trauma patients who are candidates for this procedure.
