AbstractWe report the successful single-stage hybrid management of Kommerell's diverticulum associated with a right-sided aortic arch in a 63-year-old woman. She underwent total aortic arch debranching utilizing a surgeon-customized vascular prosthesis, without cardiopulmonary bypass or deep hypothermic circulatory arrest, and concomitant zone-0 endovascular stent–graft deployment.
