RESUMEN

INTRODUCTION: In trauma patients with pelvic fractures, computed tomography (CT) scans are a critical tool to evaluate life-threatening hemorrhage. Contrast extravasation, or "blush", on CT may be a sign of bleeding, prompting a consult for angiography and possible embolization. However, the utility of blush on CT is controversial. We sought to evaluate our experience with patients who sustained pelvic fractures and had blush on CT. METHOD: A retrospective review was performed for all patients with blunt pelvic fractures between January 1, 2017 and December 31, 2018. Demographic, clinical, radiographic, and injury data were obtained. Comparison of mortality, hospital length of stay (LOS), and intensive care unit (ICU) LOS was performed for 3 subgroups: angio versus no angio; embo versus no embo; prophylactic embo versus therapeutic embo. We also calculated the sensitivity, specify, positive predictive value (PPV), and negative predictive value (NPV) of CT blush to predict the need for embolization. RESULTS: 889 patients were found to have a blunt pelvic fracture. 51 patients had blush on CT scan. 29 (56.9%) underwent angiography. 17 (58.6%) of these 29 patients were found to have extravasation and were embolized. 12 patients had an angio with no extravasation, and 6 of these patients (50%) underwent prophylactic embolization. No significant difference was found for hospital LOS, ICU LOS, or mortality in our 3 groups. Sensitivity, specificity, PPV, and NPV for CT blush were 74%, 96%, 33%, 99%, respectively. CONCLUSION: Patients with active extravasation undergoing embolization had similar outcomes to patients without active extravasation. Blush on CT scan had low sensitivity and low PPV but high specificity and high NPV. Future studies need to include careful attention to the CT protocol utilized as well as patient selection.
