Controlled donation after circulatory death (cDCD) has emerged as one of the main strategies for increasing the organ donor pool. Because of the ischemic injury that follows the withdrawal of life-sustaining therapies, hearts from cDCD donors have not been considered for transplantation until recently. The ex-situ perfusion of hearts directly procured from cDCD donors has been used to allow the continuous perfusion of the organ and the assessment of myocardial viability prior to transplantation. Based on our experience with abdominal normothermic regional perfusion in cDCD, we designed a protocol to recover and validate hearts from cDCD donors using thoraco-abdominal normothermic regional perfusion without the utilization of an ex-situ device.
We describe the first case of a cDCD heart transplant performed with this approach in Spain. The donor was a 43-year-old asthmatic female diagnosed with severe hypoxic encephalopathy. She was considered a potential cDCD donor and a suitable candidate for multiorgan procurement including the heart via thoraco-abdominal normothermic regional perfusion. The heart recipient was a 60-year-old male diagnosed with amyloid cardiomyopathy. Cold ischemia time was 55 min. The surgery was uneventful.
This case report, the first of its kind in Spain, supports the feasibility of evaluating and successfully transplanting cDCD hearts without the need for ex-situ perfusion based on the use of thoraco-abdominal normothermic regional perfusion opening the way for multiorgan donation in cDCD.
循环死亡后控制供体(cDCD)已成为增加器官捐献者库的主要策略之一。由于停止生命维持治疗后会发生缺血性损伤,因此直到最近,cDCD 供体的心脏才被考虑用于移植。直接从 cDCD 供体中获取的心脏的离体灌注已被用于在移植前允许器官的连续灌注和评估心肌活力。基于我们在 cDCD 中使用腹部常温区域灌注的经验,我们设计了一种方案,使用胸腹腔常温区域灌注来恢复和验证 cDCD 供体的心脏,而无需使用离体设备。
我们描述了西班牙首例使用这种方法进行的 cDCD 心脏移植。供体为 43 岁哮喘女性,患有严重缺氧性脑病。她被认为是潜在的 cDCD 供体,也是包括心脏在内的多器官获取的合适候选者,通过胸腹腔常温区域灌注进行。心脏受者为 60 岁男性,患有淀粉样心肌病。冷缺血时间为 55 分钟。手术过程顺利。
这是西班牙首例此类病例报告,支持在不需要离体灌注的情况下评估和成功移植 cDCD 心脏的可行性,基于使用胸腹腔常温区域灌注,为 cDCD 中的多器官捐献开辟了道路。
