The use of donation after circulatory death (DCD) has increased significantly during the past decade. However, warm ischemia results in a greater risk for transplantation. Indeed, controlled DCD (cDCD) was associated with inferior outcomes compared with donation after brain death. The use of abdominal normothermic regional perfusion (nRP) to restore blood flow before organ recovery in cDCD has been proposed as better than rapid recovery to reverse the effect of ischemia and improve recipients' outcome. Here, the first Spanish series using abdominal nRP as an in situ conditioning method is reported. A specific methodology to avoid restoring circulation to the brain after death determination is described. Twenty-seven cDCD donors underwent abdominal nRP during at least 60 min. Thirty-seven kidneys, 11 livers, six bilateral lungs, and one pancreas were transplanted. The 1-year death-censored kidney survival was 91%, and delayed graft function rate was 27%. The 1-year liver survival rate was 90.1% with no cases of ischemic cholangiopathy. Transplanted lungs and pancreas exhibited primary function. The use of nRP may represent an advance to increase the number and quality of grafts in cDCD. Poor results in cDCD livers could be reversed with nRP. Concerns about restoring brain circulation after death are easily solved.
在过去的十年中,循环死亡后捐献(DCD)的使用显著增加。然而,热缺血会增加移植的风险。事实上,与脑死亡后捐献相比,控制性 DCD(cDCD)的结果较差。在 cDCD 中,在器官恢复前使用腹部常温区域灌注(nRP)来恢复血流,被认为优于快速恢复以逆转缺血影响并改善受者的结果。在此,报告了第一个使用腹部 nRP 作为原位调理方法的西班牙系列。描述了一种避免在死亡确定后恢复大脑循环的特定方法。27 例 cDCD 供者接受了至少 60 分钟的腹部 nRP。37 个肾脏、11 个肝脏、6 个双侧肺和 1 个胰腺被移植。1 年无死亡censored 肾存活率为 91%,延迟移植物功能恢复率为 27%。1 年肝存活率为 90.1%,无缺血性胆管炎病例。移植的肺和胰腺表现出原发性功能。nRP 的使用可能代表一种提高 cDCD 中供体数量和质量的进展。nRP 可以逆转 cDCD 肝脏的不良结果。对死后恢复大脑循环的担忧很容易解决。
