A right-sided aortic arch (RAA) is a rare congenital anomaly, and Stanford type B dissection aneurysms involving this anomaly is also uncommon. Surgical approaches to dealing with an RAA are complicated by the unusual anatomical features of the condition. Here we report the case of a 47-year-old male who had a type B dissecting aneurysm involving an RAA with Kommerell's diverticulum. Graft replacement was successfully performed with an uneventful postoperative course.

Double aortic arch with an atretic left arch distal to the origin of left subclavian artery was diagnosed with multi-detector row computed tomography (MDCT) in two children with dysphagia. This rare type of complete vascular ring is clinically important because it may be confused with right aortic arch in mirror imaging. Anatomic details of this rare type of complete vascular ring demonstrated on MDCT facilitated appropriate surgical treatment.
