POSTOPERATIVE LIVER TRANSPLANT MONITORING WITH FINE-NEEDLE ASPIRATION BIOPSY

ALTHOUGH ACUTE rejection is not often as severe in liver grafts as in other organ transplantation, it remains one of the most frequent and important causes of liver graft impairment. In addition, clinical, biohumoral, and immunologie parameters are not always useful in establishing the diagnosis of the graft disorder. On the other hand, patient treatment requires a prompt clarification of the causes of posttransplant liver function derangement, and needle-core biopsy (NC) cannot always be employed, because of clotting abnormulilics in such pulients. Our sludy focuses on fine-needle biopsy (FNAB), in ordcr to evaluate its usefulness in differentiul diagnosis, rejection and other causes of liver graft nonfunction, as well as in respect to NC biopsy.
