Abdominal aortic aneurysm characteristics and outcomes: a single-center retrospective cross-sectional study.

Objective: The objective of the study is to evaluate the characteristics and outcomes of patients with abdominal aortic aneurysm (AAA) and its correlation with mortality in the first 30 days after the procedure was performed.

Methods: Demographic information, clinical and radiological characteristics, as well as outcomes 30 days after the procedure was performed were assessed and compared. Continuous variables were analyzed with Student's t-test and categorical with Chi-square and Fisher's exact test.

Results: Duration of the procedure (p = 0.001), blood loss (p < 0.001), age > 75 years (p = 0.027), aneurysm size > 65 mm (p = 0.01), open surgery (p = 0.001), presence of pain (p = 0.005), chronic kidney disease (p = 0.03), and rupture of the aneurysm (p < 0.001) were the factors significantly associated with mortality.

Conclusion: It is essential that patient characteristics and comorbidities are assessed, as well as factors that may affect the outcomes to predict the prognosis in patients with AAA. At present, no mortality predictive model is universally applicable and highly variable performance across different populations might need a model that adapts to the population of interest.
