Abstract

PURPOSE
Acute kidney injury (AKI) is an important postoperative complication that may impact mortality and morbidity. The incidence of AKI after elective endovascular aneurysm repair (EVAR) is not known well. The aim of this study is to assess the incidence of AKI after elective EVAR and examine the impact of AKI.
MATERIALS AND METHODS
Data were collected and analyzed retrospectively from 78 elective EVARs for abdominal aortic aneurysm (AAA) among 102 total cases of conventional EVAR performed in Inha University Hospital from 2009 to 2015. The primary endpoint was incidence and risk factors of AKI. Secondary endpoints included drop in estimated glomerular filtration rate (eGFR) and the mortality of AKI.
RESULTS
We included 78 patients (17 females, 21%; mean age, 73.9±12.5 years; mean AAA diameter, 59.3±8.9 cm), 11 (14.1%) of whom developed AKI. Within 48 hours, those with AKI experienced a decrease in eGFR from 65.5±21.2 to 51.2±19.6 mL/kg/1.73 m2, and those without AKI showed a change from 73.1±9.2 to 74.2±10.7 mL/kg/1.73 m2. There were no patients who required dialysis during follow-up (mean, 24.2±18.0 months). Development of AKI was related to operation time (odds ratio [OR], 2.024; 95% confidence interval [CI], 1.732-4.723; P < 0.010) and contrast dose (OR, 3.192; 95% CI, 2.182-4.329; P < 0.010). There were no differences in mortality between the 2 groups (P=0.784).
CONCLUSION
The incidence of AKI after EVAR was related to operation time and contrast dose, but was not associated with medium-term mortality.
