By univariate analysis, we found AAAD repair patients with 30-days mortality had a higher prevalence of cerebral malperfusion, lower pre-operative fibrinogen, longer cardiopulmonary bypass and aortic crossclamp time, and higher post-operative day 1 (POD1) creatinine and urea levels. Both pre-operative (433.80\u2009\u00b1\u2009152.59 vs. 373.46\u2009\u00b1\u2009108.31\u00a0mmol\/L, p\u2009=\u20090.038) and POD1 (559.78\u2009\u00b1\u2009162.23 vs. 391.29\u2009\u00b1\u2009145.19\u00a0mmol\/L, p\u2009&lt;\u20090.001) UA level were higher in mortality group than in survival group. In regression model, only cerebral malperfusion (OR, 7.938, 95% CI 1.252\u201350.323; p\u2009=\u20090.028) and POD1 UA level (OR, 2.562; 95% CI 1.635\u20134.014; p\u2009&lt;\u20090.001) were independent predictors of 30-days mortality in AAAD repair patients. According to the ROC curve, the POD1 UA level provided positive value for 30-days mortality in AAAD repair patients with 0.799 areas under the curve. The optimum cutoff value selected by ROC curve was 500.15\u00a0mmol\/L, with a sensitivity of 65% and a specificity of 86%.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusion<\/jats:title>\n                <jats:p>Pre- and post-operative hyperuricemia are potentially associated with worsened outcomes in AAAD surgery patients.
