The chest roentgenograms of 18 patients with ruptured aortas were studied and the radiographic features tabulated. Fifteen patients survived to undergo angiography, and 14 aortograms were available for review. Distortion of the normal aortic contour and blurring of the aortic outline occurred on the initial chest film in each of the 18 cases. Obliteration of the medial left upper lung field and displacement of the superior vena cava to the right were observed in 16 and 15 films, respectively. Increased mediastinal width was not the most common noted abnormality. The mean mediastinal width on 100 cm anteroposterior supine chest film was 8.8 cm. One patient exhibited a mediastinal width within the normal range. Other frequently occurring abnormalities included opacification of the clear space between the aorta and pulmonary artery, obliteration of the distal aortic shadow, and tracheal shift to the right. At aortography nine patients demonstrated both linear radiolucent defects across the aorta and pseudoaneurysm formations, three patients showed only pseudoaneurysms, and two exhibited only linear radiolucent defects.
对18例主动脉破裂患者的胸部X线片进行了研究，并将影像学特征制成表格。15例患者存活并接受了血管造影，其中14份主动脉造影照片可供复查。18例患者的初始胸部X线片均出现了正常主动脉轮廓的扭曲和主动脉轮廓的模糊。分别在16张和15张X线片中观察到左上肺野内侧消失和上腔静脉向右移位。纵隔增宽并非最常见的异常表现。100cm前后位仰卧位胸部X线片上的平均纵隔宽度为8.8cm。1例患者的纵隔宽度在正常范围内。其他常见的异常包括主动脉与肺动脉之间的透亮间隙模糊、主动脉远端阴影消失以及气管向右移位。在血管造影检查中，9例患者显示主动脉有线性透亮缺损和假性动脉瘤形成，3例患者仅显示假性动脉瘤，2例仅表现为线性透亮缺损。
