Postoperative chest radiographs of 70 adults who had undergone cardiopulmonary bypass surgery were evaluated. The distribution of pulmonary collapse/consolidation and pleural effusions, and the pattern of radiopacities related to drainage tubes were considered. Radiologic manifestations related to sternotomy were noted. Cases with a recorded postoperative blood loss of more than 280 ml/hour and/or an increase in mediastinal width of more than 70% had massive mediastinal hemorrhage that required reoperation. Changes in mediastinal contour were inconsistent, although total loss of mediastinal definition suggested hemorrhage or drainage tube blockage. A left apical extrapleural cap indicated massive mediastinal hemorrhage.
对70例接受体外循环手术的成人患者的术后胸部X光片进行了评估。考虑了肺萎陷/实变和胸腔积液的分布情况，以及与引流管相关的不透X线影像模式。记录了与胸骨切开术相关的放射学表现。术后失血记录超过280毫升/小时和/或纵隔宽度增加超过70%的病例发生了大量纵隔出血，需要再次手术。纵隔轮廓的变化并不一致，尽管纵隔轮廓完全消失提示出血或引流管堵塞。左肺尖部胸膜外帽状影提示大量纵隔出血。
