Abstract
Hemophilia is an X-linked recessive inherited coagulation disorder. We report the anesthesia management of a hemophilia patient who underwent arthroscopic ankle arthrodesis after living-donor liver transplantation due to cirrhosis. The 35-year-old male patient with hemophilia B was diagnosed with cirrhosis due to hepatitis C virus at the age of 23 years and underwent biologically-related partial liver transplantation at the age of 29 years. As a result, the activity of factor IX activity became normal and blood product treatment became unnecessary, but the patient required long-term immunosuppression. Perioperative coagulation factor activity monitoring was performed and an immunosuppressive drug that had been preoperatively administered were continued. General anesthesia was administered by inhalation. There was no significant fluctuation in perioperative factor IX activity. This case illustrates that even in patients with hemophilia B after living-donor liver transplantation undergoing an orthopedic surgical procedure, anesthesia management can safely be performed without perioperative coagulation factor replacement.
