OBJECTIVE: We sought to assess whether sex-related differences in timely repair of ruptured abdominal aortic aneurysm (rAAA) were associated with excess risk of early mortality in women.
SUMMARY BACKGROUND DATA: rAAA is a surgical emergency and timeliness of intervention affects outcomes. A door-to-intervention time of <90 minutes is recommended.
METHODS: All rAAA repairs in the Vascular Quality Initiative from 2003 to 2017 were reviewed. Patients were stratified by sex and time-delay cohorts. Univariate and multivariate analyses were performed.
RESULTS: There were 3719 rAAA repairs, of which 797 (21%) were performed in women. Sex did not affect repair type: open versus endovascular (21% females, each). Despite similar presentation delays [median 6 hours (inter quartile range, IQR: 3-16)], admission-to-intervention time was longer for women than men [median 1.5 hours (IQR 1-4] vs 1.2 hours (IQR 1-3), P=0.047]. Overall, 45% of patients had a >90-minute delay from admission to repair, with more women than men experiencing this delay (49% vs 44%, P=0.01). Neither were more likely to undergo transfer for treatment. After risk adjustment, female sex was associated with a 48% increase in 30-day mortality. Sex differences in mortality were no longer observed in patients with intervention delays of ≤90 minutes. In patients with >90-minute delays, a 77% increase in 30-day mortality of women over men was noted.
CONCLUSIONS: Nearly half of rAAA patients have a door-to-intervention time longer than recommended societal guidelines. Sex differences in mortality after rAAA repair seem to be driven by in-hospital treatment delays.
