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 sugested hemorrhage or drainage tube blockage. A left apical extrapleural cap indicated massive mediastinal hemorrhage.
