Abstract
Anticoagulant-related nephropathy (ARN) is a clinical syndrome of acute kidney injury in patients taking vitamin K antagonists or direct oral anticoagulants. It is associated with increased mortality and there is no specific treatment. We report the case of a 78-year-old man on dabigatran who developed macroscopic haematuria and acute kidney injury 2 weeks after mitral valve repair, reaching a peak creatinine of 415 µmol/L from a normal baseline, which was successfully treated with one course of idarucizumab. This case illustrates the efficacy of an anticoagulant reversal agent for the treatment of ARN.
