Abstract：
We present a rare double aortic arch (DAA) diagnosis incidentally on CT in a 60-year-old male who presented with pneumonia. DAA is a vascular ring that typically manifests in infants or children due to compression of the esophagus or trachea, resulting in dysphagia or dyspnea. Diagnosis of DAA in adulthood is usually due to the delayed emergence of obstructive symptoms. We present a case of DAA in an adult patient without dysphagia or dyspnea. We discuss factors that can lead to the presentation of DAA in adults. These include an absence of associated congenital disabilities, insufficient tracheal or esophageal constriction in childhood and the onset of compressive symptoms later in life from decreased vascular compliance.
摘要：
我们在一名60岁的男性肺炎患者的CT上偶然发现了罕见的双主动脉弓（DAA）诊断。DAA是一种血管环，通常表现在婴儿或儿童由于食管或气管受压，导致吞咽困难或呼吸困难。成年期DAA的诊断通常是由于阻塞症状的延迟出现。我们介绍了一例没有吞咽困难或呼吸困难的成年患者的DAA病例。我们讨论了可能导致成人出现DAA的因素。这些包括缺乏相关的先天性残疾，儿童时期气管或食管收缩不足，生命后期因血管顺应性下降而出现压迫症状。
