Conclusions

We found that sex differences in early mortality after rAAA repair persist and seem to be driven by in-hospital treatment delays. Women are more likely than men to be treated beyond the 90-minute door-to-intervention benchmark and this has a significant effect on outcomes. When patients are treated within the 90 minutes of admission, sex disparity in early mortality is no longer seen. In patients treated beyond the 90-minute benchmark, women have an alarming 77% increased risk of perioperative mortality. These findings raise concerns and awareness about triage and treatment strategies of rAAA, particularly in women.
