Incidence and Outcome of Small-for-Size Liver Grafts Transplanted in Adult Recipients

Small-for-size liver transplantation (SFS-LT) carries high morbidity and mortality after transplantation. SFS-LT is usually associated with living-donor or deceased-donor split LT; however its incidence and outcome are poorly defined in adult LT recipients who receive whole grafts (WLT). In this study, we retrospectively reviewed our cohort of 3,106 deceased-donor LT in adult recipients. We found that among the 31 split LTs, 11 (35.5%) were SFS. In contrast, there only 1.08% of the whole-graft transplants (31 out of 2,868) were SFS. Although less common, SFS-WLT is associated with poorer long-term outcome of both graft and patient survivals.
