RESUMO
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.

Liver transplantation (LTx) is the only treatment for patients with end-stage liver failure. This report focuses on 45 deceased donor liver allografts allocated through Eurotransplant as "rescue offers," which were accepted and subsequently transplanted at our center over a two-year period. These organs had been officially offered to and rejected by other transplant centers a total of 162 times prior to our acceptance. Primary nonfunction was observed in six patients. Two of them died and four were retransplanted. Overall patient survival was 84.4%. LTx with such "rescue organs" constitutes an additional transplant option and a safe mechanism to "rescue" organs within Eurotransplant.

BACKGROUND: Liver transplantation is recognized as the treatment of choice for small hepatocellular carcinomas (HCC) in patients with end-stage liver failure. However, because of limited organ availability, not all those who qualify can benefit from it. METHODS: Over a 3-year period, we accepted and subsequently transplanted 10 deceased donor liver allografts allocated through Eurotransplant. These organs had been officially offered to and rejected by other transplant centers a total of 40 times due to medical or logistical reasons prior to our acceptance. They were implanted into patients in the waiting list with HCC and cirrhosis. Recipients without HCC transplanted with such "undesirable" grafts were not included in this study. RESULTS: Two patients had initial poor graft function but subsequently recovered. There was one arterial complication requiring reintervention. Median intensive care unit and hospital stays were 6 and 28 days respectively. One patient developed renal insufficiency, but recovered after 3 months. One patient developed HCC recurrence in the allograft and underwent a successful atypical liver resection 23 months after transplantation. All patients are currently alive, with follow-up periods ranging from 5 to 36 months. CONCLUSIONS: Liver transplantation with such "livers that nobody wants" constitutes an additional option for patients with HCC and cirrhosis. The risk-benefit ratio in these instances should be evaluated on a case-by-case basis.

Eurotransplant introduced a new allocation policy in January 2003 to increase the number of liver transplants by offering centers an incentive to split deceased donor livers for 2 recipients. Centers were granted the option of choosing a suitable recipient for the second portion of the split liver from their own waiting list and, to increase the awareness for liver splitting, centers were asked by the Eurotransplant duty officer whether they would consider splitting whenever a liver that met the 50/50 rule (donor age <50 and weight >50 kg) was available. During the first year after implementing this policy, split-liver transplants increased by 67% and again by 10% during the second year (a total of 288 transplants in the 2-year period). The number of pediatric recipients of a split liver increased from 44 in 2002 to 76 in 2004 and the pediatric waiting list decreased by 36% (73 to 47) one year after implementation of the new policy. More than 95% of the 288 split liver transplants involved one adult and one pediatric recipient. Nearly three-quarters of the split liver transplants were performed at 3 centers with both a pediatric and adult waiting list and with surgeons experienced in the procedure. We conclude that Eurotransplant's liver allocation policy has increased the number of liver transplants, particularly among children, by rewarding centers that split livers for transplantation to 2 recipients without prolonging cold ischemia time. The number of centers that could benefit from this policy will increase as more surgeons are trained in the splitting procedure.
