Insights

Donation after cardiac death (DCD) liver transplants show excellent long-term survival, comparable to donation after brain death (DBD) organs. This study demonstrates DCD allografts are a viable and effective option for liver transplantation.

Area of Science:

  • Transplantation immunology
  • Hepatobiliary surgery
  • Organ donation research

Background:

  • Donation after cardiac death (DCD) donors offer a potential organ source for liver transplantation.
  • Concerns about primary nonfunction (PNF) and intrahepatic biliary strictures (IHBSs) have historically limited DCD donor utilization.
  • Limited data exists comparing long-term outcomes of DCD versus donation after brain death (DBD) liver allografts.

Purpose of the Study:

  • To compare the long-term patient and graft survival rates of liver transplants using DCD donors versus DBD donors.
  • To evaluate the incidence of primary nonfunction (PNF) and intrahepatic biliary strictures (IHBSs) in DCD liver allografts.
  • To assess the impact of donor age on outcomes in DCD liver transplantation.

Main Methods:

  • Retrospective analysis of 1436 deceased donor liver transplants (December 1998 - October 2006).
  • Comparison of 108 DCD liver transplants with 1328 DBD liver transplants.
  • Median follow-up of 48 months, analyzing patient and graft survival, and causes of graft loss.

Main Results:

  • 1-, 3-, and 5-year patient survival for DCD donors: 91.5%, 88.1%, 88.1%; graft survival: 79.3%, 74.5%, 71.0%.
  • 1-, 3-, and 5-year patient survival for DBD donors: 87.3%, 81.1%, 77.2%; graft survival: 81.6%, 74.7%, 69.1%.
  • No significant difference in patient or graft survival between DCD (younger/older than 60) and DBD donors. IHBSs (n=9) and PNF (n=4) were noted causes of graft loss.

Conclusions:

  • Liver transplantation using DCD allografts achieves excellent long-term patient and graft survival.
  • Outcomes of DCD liver allografts are equivalent to those of DBD allografts.
  • DCD donors represent a valuable and effective source for liver transplantation, challenging previous concerns.
