The study aimed to investigate the risk factors for acute kidney disease (AKD) after surgery for acute type A aortic dissection and its impact on early and late mortality. AKI stage 2 and AKI stage 3 were identified as independent risk factors for the development of AKD, and AKD was found to be an independent risk factor for early mortality.
Background: Acute kidney injury (AKI), acute kidney disease (AKD) and CKD (chronic kidney disease) were a continuous process. There has been little discussion of risk factors for AKD in the population undergoing surgery for acute type A aortic dissection (AAAD). Objective: The main objective of this study was to investigate the risk factors for AKD after surgery for acute type A aortic dissection and the impact of AKD on early and late mortality.Design: AKI was to be defined as an increase in serum creatinine to >0.3 mg/dL or 1.5 times above baseline within 7 days. AKD was defined as the kidney damage within 90 days after AKI. Logistic regression models were performed to identify the risk factors of AKD and the association between AKD and early mortality after AAAD surgery.Participants: Patients with AKI after AAAD surgery admitted in ICU from March 2009 to September 2021 were included.Key results: Among the 328 patients who developed AKI after AAAD surgery, 98 patients (29.9%) pro-gressed to AKD. Multivariable analysis revealed that AKI stage 2 (OR, 3.032) and AKI stage 3 (OR, 4.001) have been shown to be independent risk factors for the development of AKD. AKD (OR, 3.175) proved to be an independent risk factor for early mortality, while no significant difference in late mortality was observed between patients in the AKD and non-AKD groups. Conclusion: The severity of AKI after surgery of AAAD was independently associated with AKD. The occurrence of AKD had a negative impact on early mortality.Clinical trial registration: ChiCTR, ChiCTR1900021290.
