  1. Patients characteristics concerning demographics, pre-existing conditions, type of aneurysm, chosen procedure and complications. Shown are mean values ± standard deviation (SD) or percentage with total number in brackets.
  2. COPD chronic-obstructive pulmonary disease, TAAA thoracoabdominal aortic aneurysm, MACE major adverse cardiac event, AKI acute kidney injury, GAS genetic aortic syndromes.
  3. Significance was determined using Student's t-test assuming significance if *p < 0.05.
