    Abstract:
    Elderly patients with abdominal aortic aneurysms (AAA) may be deemed inoperable due to the presence of comorbid conditions. Presentation of these patients with acute rupture can then result in difficult ethical decisions regarding surgical treatment. Over six years, 80 patients were treated emergently for ruptured AAA. Of these patients, 26 (32.5%) had known aneurysms. This study was performed to determine outcome and factors affecting mortality in patients with known AAAs. There were no significant differences between known and unknown AAA groups with regard to operative risk. In the overall group (n = 80), patient delay in seeking treatment averaged 20.4 hours with a trend towards shorter times in those with known AAAs (13.8 hours) compared with the unknown group (23.6 hours; p = 0.09). Medical transport delay, however, was significantly shorter for patients with known AAA (124 minutes versus 230 minutes; p = 0.04). Overall mortality was 56 per cent (n = 45). Those patients with known AAAs had a higher mortality (69%; n = 18) than those with unknown AAAs (50%, n = 27) but this was not statistically significant (P = 0.10). In patients with known AAAs, operative death was related to patient delay, with an average delay in seeking medical advice of 21.3 hours in nonsurvivors compared with 8.6 hours in survivors (P = 0.04). No other risk or demographic factors correlated with mortality. Despite a known AAA, significant delay in seeking medical advice occurred, and this delay resulted in decreased survival. Patient education is imperative if nonoperative treatment is chosen.(ABSTRACT TRUNCATED AT 250 WORDS)
