Right aortic arch with retroesophageal segment is a rare anomaly with distinctive roentgenographic features. We present 2 patients, who on the barium oesophogram had an additional finding which has not previously been described. The typical features include an indentation on the right upper barium filled oesophagus (in the antero-posterior view), an oblique indentation descending from right to left (caused by the retroesophageal segment) and the left descending aorta. The oblique identation has not previously been described. The embryology and incidence of the lesion are briefly discussed.
右位主动脉弓伴食管后段是一种罕见的异常情况，具有独特的X线特征。我们报告2例患者，其钡餐食管造影有一项此前未被描述的额外发现。典型特征包括右上段钡剂充盈食管上的压迹（前后位视图）、从右向左下行的斜形压迹（由食管后段所致）以及左位降主动脉。此前尚未描述过这种斜形压迹。本文简要讨论了该病变的胚胎学及发病率。
