BackgroundDonation after circulatory determination of death (DCDD), formerly non-heart-beating donation and donation after cardiac death, has been re-introduced into clinical practice in France since June 2006 as a potential solution to organ shortage, but this kidney transplantation programme is not popular yet, mainly because of logistical concerns and uncertainty about the long-term warm ischaemia impact on transplanted kidneys.MethodsOur institution started the DCDD programme in January 2007, following the national 'BioMedicine Agency' protocol. We only considered uncontrolled donors with an initial no-flow period (i.e. delay between collapse and external cardiac massage start) <30 min. A 5-min stand-off period was observed before declaring the death and performing in situ cold perfusion, and since January 2010, normothermic subdiaphragmatic extracorporeal membrane oxygenation. All kidneys were machine-perfused using the hypothermic pulsatile preservation system before transplantation. Morphologic assessment and perfusion indexes were used to assess the suitability for transplantation.ResultsFrom January 2007 to December 2010, our team performed 58 kidney transplantations from uncontrolled Maastricht Category I and II donors. Mean recipient age was 47 ± 9 years. Male/female ratio was 45/13. Mean waiting time on transplantation registry was 30 months (4-180). Mean cold ischaemia time was 13 h 40 min (7-18) and pulsatile perfusion time 8 h (1-16). We had three cases (5%) of primary non-function (PNF) and 95% of delayed graft function. There was no increase in biopsy-proven acute rejection incidence (12.7%). Patient and graft survivals were 98 and 91.4%, respectively, at 1 year and 98 and 88%, respectively, at last follow-up. Estimated glomerular filtration rate ( Modification of Diet in Renal Disease formula) was 48 ± 16 mL/min/1.73 m(2) at 1 year and 48 ± 15 mL/min/1.73 m(2) at the last follow-up.ConclusionsDCDD kidneys are a valuable additional source of organs for transplantation. Our results show encouraging outcomes, which give rise to further interest in this donor pool. Respecting the national protocol is crucial to prevent PNF and deleterious warm ischaemia effect on transplanted kidney.
