Abstract
We report the first case of hemophilia A with factor VIII (FVIII) inhibitor who received hemodialysis via an arteriovenous (AV) fistula. Hemophilia A is a congenital deficiency of blood coagulation FVIII that is characterized by prolonged bleeding. Approximately 30% of patients with hemophilia develop allogeneic antibodies of FVIII. The inhibitors decrease the hemostatic effect of replacement therapy; thus, the prophylaxis strategy should be well designed. Prophylactic treatment with invasive procedures is needed to prevent excessive bleeding in patients with hemophilia undergoing hemodialysis. On the contrary, hemodialysis requires attention to the development of intracircuit coagulation during dialysis. Peritoneal dialysis or hemodialysis with a long-term tunneled central venous catheter has mainly been selected as the dialysis modality for patients with hemophilia and end-stage renal disease requiring renal replacement therapy because hemodialysis with an arteriovenous fistula may result in bleeding from the puncture site after each hemodialysis session. In our patient, hemodialysis was safely performed without any anticoagulant agents, and replacement therapy with FVIII concentrates prevented bleeding after puncture of the AV fistula.
