Abstract:
Objective:To explore whether renal artery involvement is an independent risk factor of acute renal injury (AKI) KDIGO stage 3 after moderate hypothermic circulatory arrest in patients with acute Stanford type A aortic dissection.Methods:From December 2015 to October 2017, 492 consecutive patients with acute Stanford A-type aortic dissection received surgical treatment, 486 of them were included in the study. All patients underwent aortic CTA to determine the extent of aortic dissection and renal artery involvement. According to the standard of Improving Global Outcomes (KDIGO), the renal function of patients after operation was graded. The risk factors of AKI KDIGO stage 3 were analyzed.Renal artery involvement and other risk factors were included in univariate analysis, and significant variables in univariate analysis were included in multivariate logistic regression analysis.Results:In 492 patients, 40 (8.13%) died in hospital, of which 6 died of severe bleeding during operation or failed to wean from cardiopulmonary bypass which lead to unable to leave the Weaning from cardiopulmonary bypass and these 6 patients were excluded in the research. Among 486 patients included in the study, 251 (51.64%) had AKI. Among them, 83 (17.08%) were in the KDIGO stage 1, 56 (11.52%) in stage 2 and 112 (23.05%) in stage 3.The results of univariate analysis showed that there were significant differences in renal artery involvement, age, time from onset to operation, D-dimer, leukocytes and platelets in peripheral blood, creatinine clearance rate, time of cardiopulmonary bypass during operation and aortic cross-clamping time( P>0.05). The above risk factors were included in multivariate logistic regression. The results showed that preoperative renal artery involvement ( OR=1.94, P=0.02), age ( OR=1.03, P=0.02), creatinine clearance rate<85 ml/min ( OR=2.28, P=0.001), and intraoperative cardiopulmonary bypass time ( OR=1.01, P=0.02) were independent risk factors. The incidence of AKI in patients with renal artery involvement was 54.65%, significantly higher than 41.98% in patients without renal artery involvement ( P>0.05). Conclusion:Renal artery involvement is an independent risk factor of AKI KDIGO stage 3 after moderate deep hypothermic circulatory arrest of acute Stanford type A aortic dissection.
