Endovascular repair of a Kommerell's diverticulum in a patient with a left-sided aortic arch and right-sided descending thoracic aorta

Thoracic aortic anomalies are rare and may be associated with pathologic vascular conditions necessitating intervention. We present a case of a patient with a left aortic arch, right descending thoracic aorta, and a Kommerell's diverticulum giving rise to an aberrant right subclavian artery. The Kommerell's diverticulum was successfully managed with a right carotid to subclavian artery bypass and thoracic endograft exclusion
