Organ shortage has driven many transplant centers to extend their criteria for organ acceptance. Graft allocation policies have been modified accordingly. This report focuses on the impact of applying the so-called rescue allocation (RA) strategy for liver transplantation (LT) in a single center within the Eurotransplant (ET) area. Liver grafts are considered for RA when the regular organ allocation is declined by at least three centers or is averted because of donor instability/unfavorable logistical reasons, thus entering a competitive or a single-recipient rescue organ offer procedure, respectively. The accepting center has the advantage to select a recipient from its own waiting list for these RA grafts. Among 253 livers accepted at the University of Heidelberg between January 2004 and December 2006, we transplanted 85 (34%) rescue-allocated livers. The indications for LT were hepatocellular carcinoma (HCC, 43%), chronic liver disease (55%), and acute liver failure (2%). Median cold ischemia time for RA grafts was 10 h (range: 4-17). The MELD score (mean +/- SD) was 13 +/- 7 (range: 6-40) and was 12 +/- 7 for recipients with HCC. Three (3.5%) primary non-functions (PNF) occurred after transplantation of RA livers. One-year patient and graft survival were 84% and 75%, respectively. A comparison between the recipients of RA livers and regularly allocated livers revealed no significant difference regarding initial poor function (IPF), PNF, and surgical complications. Furthermore, a median follow-up of 16 months revealed no significant difference regarding patient and graft survival between the two groups. The use of RA organs has increased the donor pool and transplantation dynamics with satisfying results. The unique possibility to match livers with recipients, which is left to the discretion of accepting center, should be judged according to the center's experience to decrease the waiting times for a timely rescue of organs/recipients while avoiding futile transplantations.
器官短缺促使许多移植中心扩大器官接受标准。相应地,移植配型政策也进行了修改。本报告重点介绍了在欧洲器官移植组织(ET)区域内的单个中心应用所谓的抢救性分配(RA)策略对肝移植(LT)的影响。当常规器官分配被至少三个中心拒绝或因供体不稳定/不利的后勤原因而避免时,肝移植物被认为适用于 RA,从而分别进入竞争性或单个受者抢救性器官提供程序。对于这些 RA 移植物,接受中心具有从其自身等待名单中选择受者的优势。在海德堡大学 2004 年 1 月至 2006 年 12 月期间接受的 253 个肝脏中,我们移植了 85 个(34%)抢救性分配的肝脏。LT 的适应证为肝细胞癌(HCC,43%)、慢性肝病(55%)和急性肝衰竭(2%)。RA 移植物的冷缺血时间中位数为 10 小时(范围:4-17 小时)。RA 移植物的 MELD 评分(平均值 +/- SD)为 13 +/- 7(范围:6-40),HCC 患者为 12 +/- 7。3 例(3.5%)发生原发性无功能(PNF)。移植 RA 肝脏后,1 年患者和移植物存活率分别为 84%和 75%。将 RA 肝脏和常规分配肝脏的受者进行比较,在初始功能不良(IPF)、PNF 和手术并发症方面没有显著差异。此外,两组中位随访 16 个月后,患者和移植物存活率无显著差异。RA 器官的使用增加了供体库和移植动力,取得了令人满意的结果。根据中心的经验,将肝脏与受者匹配的独特可能性留给接受中心自由裁量,应根据该中心的经验进行判断,以减少等待时间,及时抢救器官/受者,同时避免无效移植。
