A regional experience with emergency liver transplantation

Area of Science:

• Hepatology
• Transplantation Surgery
• Critical Care Medicine

Background:

• Liver transplantation for critically ill patients (UNOS status 1) has the lowest survival and highest costs.
• A regional analysis examined outcomes for 828 liver transplants between 1983-1993, focusing on 168 status 1 recipients.

Purpose of the Study:

• To evaluate survival subgroups for critically ill liver transplant recipients.
• To assess the impact of disease chronicity and retransplantation on outcomes.
• To inform organ allocation priorities for emergency liver transplant candidates.

Main Methods:

• Retrospective analysis of a 10-year regional liver transplant database (1983-1993).
• Classification of 168 status 1 recipients by disease chronicity (acute/chronic) and transplant number (primary/re-transplant).
• Comparison of one-year survival rates across subgroups and analysis of factors influencing outcomes.

Main Results:

• Overall one-year survival for status 1 recipients was 50%.
• No significant survival difference between primary acute (57%) and chronic (50%) recipients.
• Retransplantation for acute reasons (primary graft nonfunction or hepatic artery thrombosis) had better survival (44%) than for chronic reasons (20%).
• Survival for retransplanted acute cases was significantly better if a second donor was found within 3 days (52% vs. 20%).

Conclusions:

• Urgent retransplantation for primary graft nonfunction or hepatic artery thrombosis within 3 days is crucial for improving survival.
• Current organ allocation does not strongly support differentiating acute vs. chronic disease for initial status 1 transplants.
• Retransplantation for chronically failing grafts in critically ill patients is largely futile and an inefficient use of donor organs.
