N2 - INTRODUCTION: Females are at increased risk of mortality compared to males after complex endovascular aortic repair. This study aims to examine sex-related peri-operative and follow-up outcomes in patients managed with the t-Branch device.METHODS: A two-center retrospective analysis of patients managed with the off-the-shelf t-Branch device (Cook Medical Inc., Bjaeverskov, Denmark) between 1 January 2014 and 30 September 2020 was performed. Primary outcomes were sex-comparative 30-day mortality, major adverse events (MAEs) and spinal cord ischemia (SCI).RESULTS: A total of 542 patients were included; 28.0% were females. Urgent repair and type I-III thoracoabdominal aneurysms were more common among females (52.6% vs. 34%, p = 0.01, and 57.1% vs. 35.8%, p = 0.004). Technical success was similar (97.4% vs. 96.9%, p = 0.755), as well as early mortality (16.2% in females vs. 10.8% in males; p = 0.084). SCI rates were similar between groups (13.6% vs. 9.2% p = 0.183). MAEs were more common in females; 33.7% vs. 21.4% (p = 0.022). Multivariate analysis did not identify sex as an independent predictor of adverse events. The 12-month survival rate was 75.7% (SE 0.045) for females and 84.1% (SE 0.026) for males (log rank, p = 0.10).CONCLUSIONS: Sex was not detected as an independent factor of mortality, MAEs and SCI within patients managed with the t-Branch device. Feasibility was high in both groups. No significant difference was shown in survival during the 12-month follow-up.
