We describe the case of a 74-year-old man who underwent a hybrid open and endovascular approach for repair of dissecting thoracic aortic aneurysm of a right aortic arch with aberrant left subclavian artery arising from a Kommerell's diverticulum. Total debranching using a tailored quadrifurcated graft and thoracic endovascular aneurysm repair for the transverse aortic lesion were performed. The procedures were successfully accomplished with complete exclusion of the aneurysm. This hybrid procedure for complex aortic arch disease may reduce perioperative complications compared to challenging conventional open approaches.
