PurposeThe aim of this study was to assess the outcomes, incidental findings, recommendations, and adherence to recommendations on computed tomography angiography (CTA) studies obtained in the emergency department (ED) to evaluate for aortic dissection.MethodsThe institutional database of ED patients was retrospectively reviewed to identify CTA examinations for dissection during 2014. The radiology report and electronic medical records were reviewed to assess outcomes, radiology report incidental findings, and recommendations, as well as adherence to these recommendations.ResultsThere were 370 dissection CTAs performed during the 12-month study period. The average age of the patients was 63 years (range, 15-97 years). Eighty-seven patients (23.5%) had clinically significant aortic pathology including 46 patients (12.4%) with dissection and 19 (5.1%) which were new. Three hundred twenty-nine (88.9%) of patients had at least 1 incidental finding. One hundred six (28.6%) of patients had recommendations on the radiology report, and 44.3% of these were for pulmonary nodules. Thirty recommendations (28.3%) were acted upon, most commonly related to pulmonary nodule.ConclusionComputed tomography angiography is useful in detecting aortic pathology. However, emergency physicians should be aware of the potential for clinically significant incidental findings and recommendations. Adherence to recommendations was limited, and future research could investigate mechanisms to improve compliance.Copyright © 2015 Elsevier Inc. All rights reserved.
