Key result
Open surgery for ruptured abdominal aortic aneurysm resulted in an estimated median long-term survival of 6.5 years for patients surviving the initial 30-day perioperative period, which compared well to an age- and sex-matched general population.
Why the study?
Early mortality in ruptured abdominal aneurysm is high, but data on long-term outcome are scarce.
What is the long-term survival in patients who survive beyond 30 days after open repair for ruptured abdominal aortic aneurysm compared to the general population?
Observational (n=83)
No
What is the long-term survival in patients who survive beyond 30 days after open repair for ruptured abdominal aortic aneurysm compared to the general population?
For patients surviving beyond 30 days after open surgery for ruptured abdominal aortic aneurysm, long-term survival is comparable to an age- and sex-matched general population and is primarily influenced by age rather than cardiovascular comorbidities.
Extends scarce long-term survival data after open rAAA repair; leaves open applicability to endovascular-era practice.
BACKGROUND: Early mortality in ruptured abdominal aneurysm (rAAA) is high, but data on long-term outcome are scarce. The aim of this study was to investigate the long-term outcome in survivors after open surgery for rAAA in well-defined population. METHODS: This is a population-based, observational long-term follow-up (beyond 30-day mortality) study of patients surgically treated for rAAA from 2000 through 2014. Long-term survival was analysed using Kaplan-Meier estimates and compared to the general population by analyses of relative survival. RESULTS: Out of 178 patients operated for rAAA, 95 patients (55%) either died in the perioperative period, were referred from other hospitals or were lost to follow-up (two patients). Altogether 83 patients were eligible for long-term outcomes: 72 men and 11 women. Estimated median crude survival time was 6.5 years [95% confidence interval (CI) 4.8-8.2]. Men had a median survival of 7.3 years (95% CI 5.1-9.4) versus 5.4 years in females (95% CI 3.5-7.3) (P = 0.082). Reinterventions during follow-up occurred in 31 (37%). Relative survival demonstrated a slightly higher risk of death in the rAAA population compared to the general age- and gender-matched population. Age, but not comorbidities, had a significant influence on long-term survival. CONCLUSION: For survivors beyond 30 days after surgery for rAAA, long-term survival compares well to that of an age- and sex-matched population. A high frequency of cardiovascular comorbidities did not seem to affect long-term survival.

Reite et al. (2020) conducted an observational in Ruptured abdominal aortic aneurysm (rAAA) (n=83). Open surgery for ruptured abdominal aortic aneurysm vs. Age- and sex-matched general population was evaluated on Median crude survival time (95% CI 4.8-8.2). Open surgery for ruptured abdominal aortic aneurysm resulted in an estimated median long-term survival of 6.5 years for patients surviving the initial 30-day perioperative period, which compared well to an age- and sex-matched general population.
