Summary

Accumulating marginal liver graft criteria negatively impacts liver transplant outcomes. Livers with three or more risk factors show reduced graft survival and increased delayed graft dysfunction, necessitating careful donor selection.

Area of Science:

  • Hepatology
  • Transplantation Surgery
  • Organ Donation

Background:

  • Liver transplantation (LT) outcomes depend on donor graft quality.
  • Marginal liver grafts, defined by specific donor characteristics, pose challenges.
  • Assessing the cumulative impact of these marginal criteria is crucial for improving LT success rates.

Purpose of the Study:

  • To evaluate the effect of accumulating marginal liver graft criteria on immediate liver transplant outcomes.
  • To determine if a higher number of marginal criteria correlates with poorer graft and recipient survival.

Main Methods:

  • Retrospective analysis of 325 consecutive liver transplants in 293 patients.
  • Development of a marginal liver score based on donor age, ICU stay, ischemia times, hemodynamic instability, and liver function tests (bilirubin, ALT, AST).

  • Inclusion of vasopressor use and serum sodium levels as additional risk factors.

    • Main Results:

    • Recipient survival was not significantly affected by the combined marginal criteria.
    • Graft survival decreased significantly in recipients receiving marginal livers with a score of 3 or more (P=0.045).
    • A higher delayed graft non-function rate was observed with marginal livers scoring 3 or more (P=0.03).

    Conclusions:

    • The cumulative effect of multiple marginal liver graft criteria significantly impacts graft survival and function post-transplantation.
    • Careful review or refusal of marginal liver donors with >3 risk factors is recommended to mitigate cumulative graft dysfunction.
    • Optimizing donor selection through a robust marginal liver score can improve liver transplant outcomes.
