Acute aortic dissection in an adult patient with retro-oesophageal aortic arch.

Figure 2: (A, anterior view) Volume-rendering reconstruction from computed tomography scan revealed that the following branches were arising from the abnormal aortic arch: left common carotid artery, right common carotid artery, right subclavian artery and left subclavian artery. The left common carotid artery contributed to the partial vascular ring; however, there were no symptoms of trachea-oesophageal compression in this patient.
