Abstract

Objective: The clinical significance of family history (FH) of aortic disease on the outcomes of fenestrated and branched endovascular aneurysm repair (FB-EVAR) has not been well described. This study aimed to assess how FH of aortic disease affects outcomes following FB-EVAR for complex aortic aneurysms (CAAs). Methods: This study retrospectively reviewed the clinical data of consecutive patients enrolled in 10 ongoing, prospective, non-randomised, physician sponsored, investigational device exemption studies to evaluate FB-EVAR (2005 – 2022) in the United States Aortic Research Consortium database. Patients were stratified by presence or absence of FH of any aortic disease in any relative. Patients with confirmed genetically triggered aortic diseases were excluded. Primary outcomes were 30 day major adverse events (MAEs) and late survival. Secondary outcomes included late secondary interventions and aneurysm sac enlargement. Results: During the study period, 2 901 patients underwent FB-EVAR. A total of 2 355 patients (81.2%) were included in the final analysis: 427 (18.1%) with and 1 928 (81.9%) without a FH of aortic disease. Patient demographics, clinical characteristics, and aneurysm extent were similar between the groups. Patients with a FH of aortic disease more frequently had prior open abdominal aortic repair, but less frequently had prior endovascular aneurysm repair (p < .050). There were no statistically significant differences in 30 day mortality (4% vs. 2%; p = .12) and MAEs (12% vs. 12%; p = .89) for patients with or without a FH of aortic disease. Three year survival estimates were 71% (95% confidence interval [CI] 67 – 78%) and 71% (95% CI 68 – 74%), respectively (p = .74). Freedom from secondary intervention and aneurysm sac enlargement were also not statistically significantly different between groups. Conclusion: A FH of aortic disease had no impact on 30 day or midterm outcomes of FB-EVAR of CAAs. In the absence of an identified genetically triggered aortic disease, treatment selection for CAAs should be based on clinical risk and patient anatomy rather than FH of aortic disease.
