Widening of the mediastinum after blunt, deceleration injuries to the chest in three patients suggested thoracic aortic lacerations. In each patient, the aorta was found to be intact and the iatrogenic hydromediastinum was caused by malpositioned central venous pressure lines. The radiographic appearance of the central venous pressure catheter is illustrated and clinical characteristics of the malpositioned catheter are discussed.
3例胸部钝性减速伤后纵隔增宽提示胸主动脉撕裂伤。但在每例患者中，主动脉均完好无损，医源性水纵隔是由中心静脉压导管位置不当所致。文中展示了中心静脉压导管的影像学表现，并讨论了导管位置不当的临床特征。
