Objectives: The aim of this study is to determine the incidence of contrast-induced nephropathy (CIN) after computed tomography angiography (CTA) in orthopedic trauma patients. Design: Retrospective chart review. Setting: Mount Sinai St. Luke's-Roosevelt patient data. Patients and Methods: Patients who presented to our Level I emergency department after a trauma who were diagnosed with a high energy or penetrating injury to an extremity or pelvis and who underwent CTA as a part of their initial work-up from July 2004 to June 2014. Intervention: The incidence of CIN was assessed. Main Outcome Measurements: The main outcome measure was the development of CIN after CTA. CIN was defined as an increase in baseline creatinine of 25% or greater or an increase in baseline creatinine of 0.5 mg/dL within 48–72 h of contrast exposure. Results: A total of 51 patients were included in this study. Of these patients, 27 had a repeat creatinine level available for review. The incidence of CIN was found to be 3.7% in this specific population of patients. The creatinine level of the 1 patient who developed CIN normalized by hospital day 2. None of the patients included in this study developed symptoms of or were readmitted for kidney injury. Conclusions: This review supports the use of CTA as a relatively safe diagnostic tool in orthopedic trauma patients.
