Key result
Acute aortic occlusion surgery is associated with a ~39% reduction in 30-day mortality over time.
Why the study?
Acute aortic occlusion is a rare and life-threatening event, prompting investigation into affected patients and their outcomes following surgical treatment in a population-based cohort.
Population
693 cases of surgical treatment for acute aortic occlusion in Sweden
Design
Nationwide population-based registry cohort study
Follow-up
Mean ± SD 5.2 ± 5.5 years

AAO carries substantial early mortality despite temporal decline; leaves open optimal strategies as graft-related cases increase.
Cohort (n=693)
Yes
Absolute Event Rate: 15.5% vs 25.5%
p-value: p=0.007
Mortality after surgical treatment of acute aortic occlusion has improved over a 21-year period, though it remains high, with an increasing proportion of cases due to occluded grafts or stents.
Grip et al. (2019) conducted a cohort in Acute aortic occlusion (n=693). Surgical treatment for acute aortic occlusion (2008-2014) vs. Surgical treatment for acute aortic occlusion (1994-2000) was evaluated on 30-day mortality (p=0.007). Surgical treatment for acute aortic occlusion was associated with a decrease in 30-day mortality over time, from 25.5% in 1994-2000 to 15.5% in 2008-2014 (p=0.007).
