Donantes a corazón parado tipo III de Maastricht: una opción real

Donation after circulatory death and its expansion in Spain

PURPOSE OF REVIEW

Donation after circulatory death (DCD) is still performed in a limited number of countries. This article summarizes the development of DCD in Spain and presents recent Spanish contributions to gain knowledge on the potential benefits and the practical use of normothermic regional perfusion (nRP).

RECENT FINDINGS

DCD now contributes to 24% of deceased donors in Spain. The development of DCD has been based on an assessment of practices in the treatment of cardiac arrest and end-of-life care to accommodate the option of DCD; the creation of an adequate regulatory framework; and institutional support, professional training and public education. Appropriate posttransplant outcomes have been obtained with organs from both uncontrolled and controlled DCD donors. nRP is increasingly used, with preliminary data supporting improved results compared with other in-situ preservation/recovery approaches. Mobile teams with portable extracorporeal membrane oxygenation devices are making nRP possible in hospitals without these resources. To avoid the possibility of reestablishing brain circulation after the determination of death, a specific methodology has been validated.

SUMMARY

DCD has been successfully developed in Spain following a streamlined process. nRP may become a standard in DCD, although further evidence on the benefits of this technology is eagerly awaited.

[Liver transplant with donated graft after controlled cardiac death. Current situation]

An increasing pressure on the liver transplant waiting list, forces us to explore new sources, in order to expand the donor pool. One of the most interesting and with a promising potential, is donation after cardiac death (DCD). Initially, this activity has developed in Spain by means of the Maastricht type II donation in the uncontrolled setting. For different reasons, donation after controlled cardiac death has been reconsidered in our country. The most outstanding circumstance involved in DCD donation is a potential ischemic stress, that could cause severe liver graft cell damage, resulting in an adverse effect on liver transplant results, in terms of complications and outcomes. The complex and particular issues related to DCD Donation will be discussed in this review.
