[The role of HCV in the pathogenesis of post-transfusion hepatitis].

: Between January 1987 and April 1988 following 462 open heart surgery operations, 83 patients with icteric hepatitis were seen. Among them 59 patients were anti-HCV positive with the Ortho anti-HCV test, these findings suggested a hepatitis C virus infection. The source of viral infection was searched, and a prothrombin complex concentrate which had been used during that period, seemed to be the potential cause of bloodborne hepatitis C. The results suggest that special care is required when using such blood products.
