Why the study?
Symptomatic non-ruptured abdominal aortic aneurysm represents an intermediate entity between elective aneurysms and ruptured disease, prompting a comparison of perioperative outcomes and acute kidney injury against asymptomatic cases.
Does open surgical repair for symptomatic non-ruptured abdominal aortic aneurysm result in worse perioperative outcomes compared to asymptomatic abdominal aortic aneurysm?
Population
178 patients undergoing open surgical repair for infrarenal abdominal aortic aneurysm
Comparison
Symptomatic vs asymptomatic abdominal aortic aneurysms
Design
Retrospective cohort study
Key result
Open surgical repair for symptomatic non-ruptured abdominal aortic aneurysms resulted in higher overall postoperative complications compared to asymptomatic cases (28.3% vs. 9.3%; p=0.001).

Symptomatic AAA patients may warrant closer perioperative monitoring; leaves open optimal repair timing in prospective studies.
Cohort (n=178)
Does open surgical repair for symptomatic non-ruptured abdominal aortic aneurysm result in worse perioperative outcomes compared to asymptomatic abdominal aortic aneurysm?
Absolute Event Rate: 28.3% vs 9.3%
p-value: p=0.001
Open surgical repair of symptomatic non-ruptured abdominal aortic aneurysms is associated with higher complication rates and longer hospital stays compared to asymptomatic cases, but similar rates of acute kidney injury and 30-day mortality.
Batinić et al. (2026) conducted a cohort in Infrarenal abdominal aortic aneurysm (n=178). Open surgical repair for symptomatic abdominal aortic aneurysm vs. Open surgical repair for asymptomatic abdominal aortic aneurysm was evaluated on Overall postoperative complications (p=0.001). Open surgical repair for symptomatic non-ruptured abdominal aortic aneurysms resulted in higher overall postoperative complications compared to asymptomatic cases (28.3% vs. 9.3%; p=0.001).
