ABSTRACT
BACKGROUND:
Abdominal aortic aneurysm (AAA) screening has been offered to 65-year-old men living in Oslo, Norway, since May 2011. A significant number of AAA-related deaths occurred in individuals who are not eligible for screening. The primary aim of this study was to describe the group of patients admitted to Oslo University Hospital with a ruptured AAA after the implementation of the local AAA screening project. The following parameters were investigated AAA detection before rupture, surveillance status, eligibility for screening, and comorbidities. We also sought to compare outcomes (repair rates and 30-day mortality) between patients with and without an incidentally detected AAA prior to rupture.METHODS:
This cohort study included patients admitted acutely to Oslo University Hospital due to a symptomatic or ruptured AAA in the period January 2011 to December 2022. Data on demographics, prior AAA detection, surveillance status, treatment, and mortality were collected retrospectively through electronic medical records.RESULTS:
We identified 200 patients with a symptomatic or ruptured AAA, among which 79 (40%) had an AAA detected before rupture-one (1%) through screening and 78 (39%) incidentally. Up to 30% of the incidentally detected AAAs were not under any surveillance. Six patients were found eligible for screening one had attended, three were non-attenders, and two had not been invited. Patients with an incidentally detected AAA before rupture had a more advanced age and a significantly higher degree of comorbidities than patients without a previously detected AAA, and the repair rates in these groups were 56% and 84%, respectively (P < 0.001). Adjusted for comorbidities and risk factors, the odds ratio for repair among patients with incidentally detected AAA was 0.56 (P = 0.292). The 30-day mortality was not significantly different between the two groups (P = 0.097).CONCLUSIONS:
Most patients with a ruptured AAA were not eligible for screening, but 39% of the patients had an incidentally detected AAA prior to rupture. Standardized reporting and follow-up of incidentally detected AAAs is thus identified as an additional measure to organized screening in the effort to reduce AAA-related mortality.
