Key result
In patients surviving more than 30 days after surgery, long-term cumulative survival at 5 years was not significantly different between those who underwent emergency repair for ruptured abdominal aortic aneurysms and those who had elective repair for non-ruptured aneurysms (71.1% vs 76.0%, p=0.06).
Why the study?
Does long-term survival differ between ruptured and non-ruptured abdominal aortic aneurysm patients who survive synthetic graft replacement surgery?
Cohort (n=100)
No
Does long-term survival differ between ruptured and non-ruptured abdominal aortic aneurysm patients who survive synthetic graft replacement surgery?
Patients who survive surgery for a ruptured abdominal aortic aneurysm have long-term survival rates comparable to those undergoing surgery for non-ruptured aneurysms.
Comparable 5-year survival after surviving ruptured AAA repair may inform expectations; leaves open confirmation in larger prospective cohorts.

Shin Yamamoto (1999) conducted a cohort in Abdominal aortic aneurysm (n=100). Emergency repair for ruptured abdominal aortic aneurysm vs. Elective repair for non-ruptured abdominal aortic aneurysm was evaluated on Long-term cumulative survival at 5 years (excluding operative deaths) (p=0.06). In patients surviving more than 30 days after surgery, long-term cumulative survival at 5 years was not significantly different between those who underwent emergency repair for ruptured abdominal aortic aneurysms and those who had elective repair for non-ruptured aneurysms (71.1% vs 76.0%, p=0.06).
