چکیده (انگلیسی):

The suitable size of a graft is a key element in the success of liver transplantation.
A small-for-size liver graft is very likely to sustain a significant degree of injury as a result of
ischemia, preservation, reperfusion, and rejection. Usually, small-for-size grafts are a concern
in living-donor liver transplantation rather than in deceased-donor liver transplantation. Here,
we describe the successful transplantation of a liver from a 2-year-old deceased donor to a 61-
year-old male recipient who suffered from liver failure related to hepatitis B. No report of
successful deceased-donor liver transplantation with discrepancies between donor and recipient
age and size to such an extent has been found in the literature. Despite unusually large
discrepancies, with effort in minimizing the ischemic time, revised surgical techniques, and
strong regenerative power of the “young” graft, the old patient’s liver function gradually returned
to normal. This again proves that the definition of a “suitable graft” evolves with time
and experience.
