  • OBJECTIVE: There is growing evidence of a female patient disadvantage in complex endovascular aortic repair using fenestrated and branched endografts (FB-EVAR) primarily related to peri-procedural events including ischaemic and access vessel complications. This study aimed to determine the impact of sex differences on treatment patterns, and in hospital outcomes in a single centre cohort.

    METHODS: This was a retrospective cross sectional single centre cohort study of all consecutive FB-EVAR procedures provided to patients with asymptomatic pararenal and thoraco-abdominal aortic aneurysm (TAAA) between 1 January 2010 and 28 February 2021. Adjusted multivariable logistic regression models were developed using backward (Wald) elimination of variables to determine the independent impact of female sex on short term outcomes.

    RESULTS: In total, 445 patients (24.3% females, median age 73.0 years, IQR 66, 78) were included. Female patients had a smaller aneurysm diameter, less frequent coronary artery disease (29.6% vs. 44.8%, p = .007) and history of myocardial infarction (2.8% vs. 15.4%, p < .001) when compared with males. Females were more frequently treated for TAAA than males (49.1% vs. 25.2%, p < .001). The median length of post-procedural hospital stay was 10 days in females and 9 in males. In adjusted analyses, female sex was independently associated with higher mortality (odds ratio [OR] 10.135, 95% CI 2.264 - 45.369), post-procedural complications (OR 2.500, 95% CI 1.329 - 4.702), spinal cord ischaemia (OR 4.488, 95% CI 1.610 - 12.509), sepsis (OR 4.940, 95% CI 1.379 - 17.702), and acute respiratory insufficiency (OR 3.283, 95% CI 1.015 - 10.622) after pararenal aortic aneurysm repair during the hospital stay.

    CONCLUSION: In this analysis of consecutively treated patients, female sex was associated with increased in hospital mortality, peri-procedural complications, and spinal cord ischaemia after elective complex endovascular repair of pararenal aortic aneurysm, while no differences were revealed in the TAAA subgroup. These results suggest that sex related patient selection and peri-procedural management should be studied in future research.
