ObjectiveTo determine whether preoperative chronic kidney disease (CKD) is predictive of poor outcomes in patients who undergo Crawford extent II thoracoabdominal aortic aneurysm (TAAA) repair.MethodsData were collected from patients with CKD (defined as a preoperative estimated glomerular filtration rate <60 mL/min/1.73 m2; n = 399) and without CKD (n = 604) who underwent extent II TAAA repair during 1991 to 2016. We used univariate, multivariable, and propensity score matching analyses to compare outcomes between these 2 groups.ResultsCompared with patients without CKD, patients who presented with CKD were older and had greater rates of comorbidities, including coronary artery disease, cerebrovascular disease, and peripheral vascular disease. Patients with CKD had higher rates of operative mortality and adverse events. After propensity analysis, patients with CKD had greater rates of adverse event and renal failure necessitating dialysis, but had comparable rates of operative death to patients without CKD. Multivariable modeling indicated that CKD independently predicted adverse event (relative risk ratio [RRR] = 1.61; P = .01) and renal failure (RRR = 1.86; P = .02) after repair. After adjustment for median age, patients with CKD had substantially worse mid-term survival than those without (23.9 ± 2.4% vs 48.5 ± 2.5% at 10 years; P < .001).ConclusionsIn patients who present with CKD, extent II open TAAA repair carries considerable risks of operative death and adverse events. Further investigation is needed to improve renal protection during such repair.Copyright © 2018 The American Association for Thoracic Surgery. Published by Elsevier Inc. All rights reserved.
