The results of aortic arch replacement using antegrade cerebral perfusion in haemodialysis patients: analysis of the Japan cardiovascular surgery database

Eur J Cardiothorac Surg. 2021 Dec 27;61(1):162-169. doi: 10.1093/ejcts/ezab252.


Objectives: There have been limited data available regarding aortic arch replacement in dialysis patients. The purpose of this study was to examine real-world data and to determine the impact of preoperative dialysis status and other risks on surgical aortic arch replacement using the Japan Cardiovascular Surgery Database.

Methods: A total of 5044 patients who underwent elective, isolated aortic arch replacement using antegrade cerebral perfusion during 2014-2017 were eligible for the study. Of these, 89 patients received haemodialysis preoperatively. The patients were divided into 6 groups according to their preoperative estimated glomerular filtration rate and dialysis status for comparison. Preoperative and postoperative data were examined using a multivariable regression model.

Results: The overall surgical mortality rates of non-Chronic Kidney Disease (CKD) (estimated glomerular filtration rate >60 ml/min/1.73 m2), stage 3A, stage 3B, stage 4, stage 5 CKD and dialysis patients were 2.6%, 3.1%, 6.8%, 11.6%, 16.7% and 13.5%, respectively. After risk adjustment, dialysis was shown to be strongly associated with surgical mortality (odds ratio 4.39 and 95% confidence interval 2.22-8.72) and have a trend to be associated with postoperative stroke (odds ratio 2.02, 95% confidence interval 1.00-4.10, P = 0.051) when compared to the non-CKD group. As predictors of mortality, male sex, peripheral arterial disease, preoperative liver dysfunction and impaired left ventricular function were identified.

Conclusions: The Japanese nationwide database revealed the outcomes of aortic arch replacement in dialysis patients. Appropriate counselling and an alternative strategy should be considered for such patients with multiple risks for mortality.
