Post-dissection thoraco-abdominal aneurysms: Results of open and endovascular repair

Abstract Introduction/Objectives: Repair of post-dissection thoraco-abdominal aortic aneurysms (PD-TAAA) is a complex challenge. Choosing the correct approach to manage these aneurysms is not straightforward as both open and endovascular strategies are valid. Our aim was to analyze and compare the results of PD-TAAA treated by endovascular or open surgery. Methods: A seven-year (January-2013 and May-2020) single-center retrospective cohort study of patients with PD-TAAA treated by endovascular (group-1) or open (group-2) surgery was conducted. Primary outcome was in-hospital mortality. Secondary outcomes were organ lesion, in-hospital infections, length of stay (LOS), endoleaks, branch occlusions, re-interventions and mortality during follow-up. Results: Twenty-one patients (15-men) were treated: 8 in group-1 and 13 in group-2. The mean age was lower in group-2 [68 (SD:11) versus 48 (SD:12), p=0.004]. Three patients had connective tissue disease (CTD). Group-1 patients had a higher ASA score (p
