The development of a high-titer factor V inhibitor is described in a patient who underwent orthotopic liver transplantation followed by porcine xenoperfusion after an acute rejection episode. The inhibitor showed no cross-reactivity to either porcine or bovine factor V, nor was it accessible to human platelet factor V. The limitations of treatment modalities including intravenous immunoglobulin, steroids, cytotoxic therapy, intense plasmapheresis and platelet transfusions are discussed.
