AbstractA 74-year-old Pacific Island man with end-stage renal failure planning to start haemodialysis presented with persistent bleeding after tunnelled dialysis catheter insertion. The laboratory findings revealed a prolonged activated partial thromboplastin time of 118 s, prothrombin ratio of 4.2, factor V activity of <2% and a factor V inhibitor of 40 Bethesda Units. No clear underlying aetiology was identified. The bleeding settled with conservative measures and the factor V inhibitor was successfully treated with oral cyclophosphamide for 6 weeks.© 2022 Royal Australasian College of Physicians.
