Objectives:
Persistent organ shortages have driven increased use of marginal criteria liver grafts in transplants. We conducted a retrospective single -center analysis of liver transplants performed from November 1, 2023, through January 31, 2025, to compare short-term outcomes between marginal criteria grafts and standard criteria grafts.
Materials And Methods:
Donors were classified according to established definitions of extended criteria, and the assessed outcomes included peak liver enzymes, Model for End -Stage Liver Disease scores, and posttransplant complications.
Results:
Of 18 transplants, 12 (66.6 % )were marginal criteria grafts. Peak levels of alanine transaminase and aspartate transaminase, Model for End -Stage Liver Disease scores, and overall complication rates were comparable between groups. One recipient of a marginal criteria graft died from primary graft failure, and 1 required a retransplant.
Conclusions:
Our findings suggest that, with careful donor -recipient selection and perioperative management, marginal criteria liver grafts can achieve acceptable short -term outcomes and safely expand the donor pool.
