Double aortic arch is a rare vascular anomaly, particularly in adults. Most of patients were infants or children. In this report we describe a case of the incomplete double aortic arch in a 55 years old woman complaining of esophageal symptoms was found by esophagography and examined by MR imaging. This anomaly had double aortic arch with partial atresia of the left arch. The right common carotid artery (RCCA) and the right subclavian artery (RSA) arose from the large right aortic arch (RAA). The left common carotid artery (LCCA) and subclavian artery (LSA) arose from the left aortic arch (LAA). Aortic diverticulum was detected at the interior site of the descending aorta connected with the left subclavian artery (LSA). The mediastinal organs were surrounded by the vascular ring (RAA, LAA, LSA and aortic diverticulum).
双主动脉弓是一种罕见的血管畸形，在成人中尤为罕见。大多数患者为婴儿或儿童。在本报告中，我们描述了一例55岁女性的不完全双主动脉弓病例，该患者因食管症状行食管造影检查，并接受了磁共振成像检查。该畸形表现为双主动脉弓，左弓部分闭锁。右颈总动脉（RCCA）和右锁骨下动脉（RSA）发自粗大的右主动脉弓（RAA）。左颈总动脉（LCCA）和锁骨下动脉（LSA）发自左主动脉弓（LAA）。在降主动脉与左锁骨下动脉（LSA）相连处的内侧发现主动脉憩室。纵隔器官被血管环（RAA、LAA、LSA和主动脉憩室）包绕。
