[Profuse Hemorage During Open Heart Surgery in a Patient Late After Liver Transplantation and Remission Stage...

A 72-year-old male presented with severe mitral regurgitation, moderate tricuspid regurgitation, and chronic atrial fibrillation. One month prior, he encountered difficulties with dialysis and was subsequently referred to our department for cardiac surgery. The patient's medical history includes living-donor liver transplantation for type C cirrhosis associated with acquired hemophilia A. The preoperative liver function was categorized as Child-Pugh grade B, with a model for end-stage liver disease( MELD) score of 23. His factor Ⅷ activity was close to the lower limit of the normal range. The patient underwent mitral valve replacement, tricuspid valve repair, and left atrial appendage closure. Initially, he experienced intractable bleeding, but hemostasis was easily achieved after administrating a factor Ⅷ preparation. Upon admission to the intensive care unit, his factor Ⅷ clotting activity was slightly below the normal range. Therefore, in cases where a patient with remission stage hemophilia A resulting in liver transplantation undergoes open heart surgery, it is crucial to have coagulation factor medication readily available, regardless of normal preoperative factor Ⅷ levels.
