Vascular ring

Case contributed by A.Prof Frank Gaillard

Barium swallow

Barium swallow demonstrates a concentric attenuation of the barium contrast in the superior mediastinum.


CT chest with contrast

The patient was then scanned with dynamic contrast administration, with a esophageal boogie in situ (to better delineate the esophagus). 

CTA of the chest obtained with a boogie in esophagus (trachea anterior to it not seen) demonstrates a mirror image aortic arch with aberrant left subclavian artery (order of vessel origin from the aortic arch: left CCA, right CCA, right subclavian, left subclavian) which passes behind the esophagus creating an incomplete ring.

Case Discussion

Incomplete vascular ring, in this case caused by a right sided aortic arch with mirror anatomy and an aberrant left subclavian artery. The mirror anatomy is a marker for likely co-existing congenital heart disease (not sure of any such defects in this patient).
