Aspiration cytology of a human liver allograft

We have analyzed one human liver transplant by frequent FNABs. We conclude that FNABs of liver transplant recipients is a safe procedure that can be performed repeatedly without danger to the graft or to the graft recipient. The inflammatory episodes of rejection may be recorded and certain changes in the transplant--in particular, cholestasis and deposits of CsA--may be demonstrated in the FNAB as well.
