No evidence-based recommendations exist for imaging surveillance of grade I blunt thoracic aortic injuries (BTAI). We aimed to evaluate the natural history of these injuries to provide guidance for follow-up imaging.Patients that presented to our trauma center from 2008 to 2021 with grade I BTAI were retrospectively evaluated. CT angiography images were assessed for initial injury grade and subsequent stability, improvement, worsening, or resolution.Of 83 patients who had grade I injuries and repeat imaging, 57.8% had complete resolution, 20.5% had improvement, and 18.1% had stability of their injury. Only seven patients (8.4%) demonstrated worsening of their injury. Six patients had eventual resolution and one underwent endovascular repair that would not have been performed under current practice patterns.Since grade I injuries do not worsen to require later surgical intervention, early surveillance imaging is not necessary and further imaging may not be necessary at all. |
