Computed tomography (CT) is a sensitive and specific test for thoracic aortic injury, and is the choice of diagnostic test for adult patients. However, the diagnostic accuracy of conventional CT in pediatric patients has not been elucidated, and the diagnostic strategy has not been clarified. We present the case of an eight-year-old patient who had a thoracic injury, with left open pneumothorax, pulmonary contusion, and multiple left-sided rib fractures. Although the findings on conventional CT were insufficient either to diagnose or deny as having thoracic aortic injury, additional examination using electrocardiogram-gated CT angiography and three-dimensional reconstruction revealed a localized enlarged aortic diameter with an intimal flap. Electrocardiogram-gated CT may be useful for diagnosing thoracic aortic injury in pediatric patients.
计算机断层扫描（CT）是诊断胸主动脉损伤的一种敏感且特异的检查方法，是成年患者诊断检查的首选。然而，传统CT在儿科患者中的诊断准确性尚未明确，诊断策略也未阐明。我们报告一例8岁胸部受伤患者，伴有左侧开放性气胸、肺挫伤和多发左侧肋骨骨折。尽管传统CT检查结果不足以诊断或排除胸主动脉损伤，但采用心电图门控CT血管造影和三维重建的进一步检查发现主动脉直径局部增大并伴有内膜瓣。心电图门控CT可能有助于诊断儿科患者的胸主动脉损伤。
