The reintervention rate was calculated by using only first reintervention for each segment of the aorta for each patient. Root reintervention includes sternotomy aortic root replacement. Arch reintervention includes sternotomy arch replacement. Descending reintervention includes open thoracotomy or thoracoabdominal incision and TEVAR for thoracic or thoracoabdominal aneurysm repair. Abdominal reintervention includes isolated abdominal aortic aneurysm repair.
