Byrne R, Parks A, Hazelton JP, et al. - Researchers evaluated injuries identified on secondary CT imaging after identification of injuries on initial CTs in blunt trauma patients, regarding their incidence and significance. This retrospective cohort study comprised 537 patients who underwent 1,179 initial CT scans which identified 744 injuries. The patients underwent 1,094 secondary CTs that led to the recognization of 143 additional injuries in 94 (18%) patients. The most common injury on secondary scans was rib fracture(s) [45/143 (32%)]. However, there were only 1.7% of patients who had a resultant major management change. Tube thoracostomy for pneumothorax (4 patients), blood transfusion for hemoperitoneum (1 patient), surgery for acetabular fracture (1 patient), thoracolumbar brace for spine fracture (2 patients) and angiography for splenic injury (1 patient) were the major management changes undertaken.
