The clinical, roentgenographic and aortographic data were reviewed in 12 patients with localised descending, thoracic aortic aneurysms. The current study indicates that arteriosclerotic peripheral vascular disease not infrequently produced localised saccular aneurysms of the descending thoracic aorta. Characteristic symptomatology was unusual; most aneurysms were detected as incidental roentgenographic findings. The aneurysms projected from the posteroloteral aspect of the aorta and roentgenographically appeared as left hilar masses or left retrocardiac masses when located in the mid and lower descending thoracic aorta, respectively. Specific rim calcification or vertebral erosion was not encountered in any case. During aortography only a small portion of the aneurysm was outlined with contrast material due to partial obliteration of the aneurysmal cavity with thrombus.
对12例局限性降胸段主动脉瘤患者的临床、X线及主动脉造影资料进行了回顾。当前研究表明，动脉硬化性外周血管疾病常导致降胸段主动脉局限性囊状动脉瘤。特征性症状并不常见；大多数动脉瘤是在X线检查时偶然发现的。动脉瘤从主动脉的后外侧突出，位于降胸段主动脉中下段时，X线表现分别为左肺门肿块或左心后肿块。所有病例均未发现特异性边缘钙化或椎体侵蚀。主动脉造影时，由于动脉瘤腔内部分被血栓阻塞，只有一小部分动脉瘤被造影剂勾勒出来。
