Surgeons at the University of Tokyo Hospital on Wednesday began transplanting to an HIV-infected hemophiliac patient with advanced hepatitis C part of a liver donated by the patient's brother.
The 41-year-old man was infected with HIV and hepatitis C by contaminated blood products he received during hemophilia treatment.
He will receive part of his 48-year-old brother's liver in an operation that was expected to last until the early hours of this morning, the doctors said.
