Two newborn infants presented with acute respiratory distress. In both cases, the left lung was opaque, hyperinflated, and associated with a rightward shift of the mediastinum. A diagnosis of retained fetal fluid secondary to vascular compression of the left bronchus by the ductus arteriosus was made by combining various imaging methods including chest radiograph, computed tomography (CT), and echocardiography. Although the initial chest radiographs were similar, the mechanisms of obstruction were different. The imaging emphasizes the importance of CT angiography to understanding the three-dimensional relationships resulting in bronchial compression.
两名新生儿出现急性呼吸窘迫。在这两个病例中，左肺均呈不透明、过度充气状态，并伴有纵隔右移。通过结合胸部X光片、计算机断层扫描（CT）和超声心动图等多种成像方法，诊断为动脉导管对左支气管血管压迫继发的胎儿液体潴留。尽管最初的胸部X光片相似，但梗阻机制不同。影像学检查强调了CT血管造影对理解导致支气管压迫的三维关系的重要性。
