Transplantation of Organs From DCD and DBD Donors Who Died After Ligature Asphyxiation.

BACKGROUND

The United Kingdom transplant registry data demonstrated similar transplant outcomes for recipients of kidneys from donors who died following ligature asphyxiation and those who received organs from donors dying from other causes. The impact that this donor cause of death has on the outcomes of other solid organ transplant recipients remains uncertain.

METHODS

The United Kingdom transplant registry analysis was undertaken to determine transplant outcomes in recipients of lungs, hearts, livers' and pancreases from donors who died following ligature asphyxiation.

RESULTS

Between January 01, 2003, and December 31, 2016, 2.7% (n = 521) of all potential United Kingdom donors died following ligature asphyxiation (mostly suicide by hanging). Of these, 416 (79.9%; 197 donation after brain stem death and 219 donation after circulatory death [DCD]) donated an organ for transplantation. These donors provided organs for 574 transplants (66 lung transplants, 75 heart transplants, 279 liver transplants, and 154 pancreas transplants). Patient and graft survival were similar for recipients of both donation after brain stem death and DCD hearts, livers, and pancreases from donors who died following ligature asphyxiation. Unadjusted graft and patient survival were significantly worse for recipients of lungs from DCD donors who died following ligature asphyxiation. This detrimental effect persisted after propensity score matching.

CONCLUSIONS

Livers, hearts, and pancreases from donors who die following ligature asphyxiation suffer an additional warm ischemic insult, but this does not negatively impact transplant outcomes. Outcomes for recipients of DCD lungs appear to be significantly worse.
