RARE COMBINATION OF ANATOMICAL VARIATIONS
Congenital variation of right aortic arch (prevalence 0.05%), aberrant left subclavian artery (posterior to the oesophagus) and 28*26mm diameter Kommerell diverticulum (prevalence 0.4-2.3%), with tracheal deviation and extrinsic esophageal compression. Symptomatic or >55mm diameter Kommerell’s diverticulum should be considered for repair due to their risk of rupture.
