The principal radiological indication for thoracic aortography following blunt chest trauma has been a widened mediastinum on chest roentgenogram. The presence or absence of sixteen findings on 100 cm anteroposterior supine chest roentgenograms were noted and compared in 47 consecutive patients who underwent aortography following blunt thoracic trauma and 100 patients without trauma. On the basis of our data, we propose six radiological indications for thoracic aortography following chest trauma: mediastinum greater than 8 cm on 100 cm AP supine chest film; tracheal shift to the right; blurring of the normally sharp outline of the aorta; obliteration of the medial aspect of the apex of the left upper lobe; opacification of the clear space between the aorta and pulmonary artery; and depression of the left main bronchus below 40 degrees.
钝性胸部创伤后进行胸主动脉造影的主要放射学指征一直是胸部X线片上纵隔增宽。在47例钝性胸部创伤后接受主动脉造影的连续患者和100例无创伤患者中，记录并比较了100 cm前后位仰卧位胸部X线片上16项表现的有无。根据我们的数据，我们提出了胸部创伤后胸主动脉造影的六项放射学指征：100 cm前后位仰卧位胸部X线片上纵隔大于8 cm；气管向右移位；主动脉正常清晰的轮廓模糊；左上叶尖内侧轮廓消失；主动脉与肺动脉之间的透亮间隙模糊；左主支气管下压低于40度。
