We present the results of a multicenter, historic cohort study comparing the predictive capacity of the psoas muscle area (PMA), radiodensity (PMD), and lean muscle area (LMA) as surrogate markers of sarcopenia, over short- and long-term outcomes after AAA repair, compared to the mFI-5 and American Society of Anesthesiologists (ASA) scales.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Retrospective review was conducted of all consecutive AAA elective repair cases (open or endovascular) in three tertiary-care centers from 2014 to 2019. Cross-sectional PMA, PMD, and LMA at the mid-body of the L3 vertebra were measured by two independent operators in the preoperative computed tomography. Receiver operating characteristic (ROC) curves were used to determine optimal cutoff values. Bivariate analysis, logistic regression, and Cox\u2019s proportional hazards models were built to examine the relationship between baseline variables and postoperative mortality, long-term mortality, and complications.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>596 patients were included (mean age 72.7 \u00b1 8\u00a0years, 95.1% male, 66.9% EVAR). Perioperative mortality was 2.3% (EVAR 1.2% vs open repair 4.6%, p = .015), and no independent predictors could be identified in the multivariate analysis. Conversely, an age over 74\u00a0years old (OR 1.84 95%CI 1.25\u20132.70), previous heart diseases (OR 1.62 95%CI 1.13\u20132.32), diabetes mellitus (OR 1.61 95%CI 1.13\u20132.32), and a PMD value over 66 HU (OR 0.58 95%CI 0.39\u20130.84) acted as independent predictors of long-term mortality in the Cox\u2019s proportional hazards model. Heart diseases (congestive heart failure or coronary artery disease), serum creatinine levels over 1.05\u00a0mg\/dL, and an aneurysm diameter over 60\u00a0mm were independent predictors of major complications.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Surrogate markers of sarcopenia had a poor predictive profile for postoperative mortality after AAA repair in our sample.
