The fenestrated Anaconda endograft was developed to address complex aortic anatomy and may mitigate sex-based disparities in outcomes. This study evaluates sex-specific results following fenestrated EVAR (FEVAR) with the Anaconda device.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>A retrospective single-centre cohort study was conducted including patients who underwent elective FEVAR using the Anaconda stent graft between 2013 and 2023.

Although the number of female patients was limited, these findings suggest that FEVAR is a feasible and safe treatment option for appropriately selected women. Given the underrepresentation of female patients in complex endovascular aortic repair, these results contribute to a better understanding of sex-specific outcomes and may encourage clinicians to consider FEVAR more frequently in women, as well as to pursue continued research focusing on sex-specific differences and long-term outcomes.<\/jats:p>\n
