Single-stage repair of the right aortic arch with Kommerell diverticulum through the right thoracotomy with SIRC approach

Kommerell diverticulum (KD) is a congenital vascular disease associated with dilatation at an aberrant subclavian artery's origin. The surgical repair should be considered for the symptomatic patients due to the adjacent organ's compression by the aneurysmal change of KD. An appropriate approach should be selected for the open repair to suit the anatomical type of disease. We reported a 50-year-old female diagnosed with KD undergoing the single-stage open repair through the right thoracotomy with the straight skin incision with rib cross.
