Objective To summarize and further investigate the initial experience of organ procurement process for organ donation after cardiac death （DCD）. Methods The clinical data，the selected standard，and the organ procurement process of 28 cases of DCD from July 2009 to January 2012 in the liver transplantation center of Guangzhou General Hospital were reviewed and analyzed. Results Twenty-eight cases of DCD all had donated organs successfully. Among these cases，there were 3 cases （10.7%） of the Maastricht Ⅲ， and one case （3.6%） of the Maastricht Ⅳ，and 24 cases （85.7%） of the organ donation after brain death plus cardiac death （DBCD）．Three cases of the Maastricht Ⅲ were practiced the organ procurement process of DCD．One case of the Maastricht Ⅳ was practiced the organ procurement process of DBCD without the extracorporeal membrane oxygenation （ECMO）．Twenty-four cases of DBCD were practiced the organ procurement process of DBCD with the ECMO．The donator warm ischemic time was zero min in DBCD，18 min in Maastricht Ⅳ，and mean 25 min （22-28 min） in MaastrichtⅢ．All the donated organs included 28 livers，40 kidneys，and 2 hearts．And all these organs had been practiced the liver transplantation，the kidney transplantation，and the heart transplantation. Conclusions The organ procurement process for organ DCD includes the DCD process and the DBCD process in China，and the later includes the organ procurement process with the ECMO and without the ECMO．The ECMO could well control the warm ischemia for protecting the donors just without ethics dispute. So，the using of the ECMO for the organ DCD of citizen in China has a very important contribution．
Objective To approach the questions of donation after cardiac death （DCD） and transplantation through analyzing the DCD cases in this hospital. Methods The organs were obtained from 4 DCD from 2010 to 2011 in this hospital， the clinical data of DCD were analyzed retrospectively. Results Seven renal transplantations and 3 liver transplantations were performed. Donor warm ischemic time was 10-40 min. The liver and left kidney of the first DCD donator （Maastricht categoryⅣ） were eliminated through biopsy. One patient exhibited delayed graft function of kidney from the first DCD，the nephrectomy had to be done on day 7 after operation due to renal allograft rupture. Nine patients received 3 livers and 6 kidneys from the other 3 DCD donators （Maastricht categoryⅢ），whose patients were alive with excellent graft function. Conclusions The use of controlled DCD （Maastricht categoryⅢ） might be an effective way to increase the number of organs available for transplantation because that it might obtain satisfactory transplant outcomes and acceptable postoperative complications. The widespread implementation of controlled DCD in China should be encouraged.
Objective To discuss the criteria of recipient selection，surgical approach，and complications and its theray by using of pediatric donation after cardiac death liver graft in adult recipient. Methods The clinical data of one case of pediatric donation after cardiac death liver to adult recipient was analyzed retrospectively and the literatures were reviewed. Results A 6-year-old girl pronounced brain death due to drowning and on the basis of cardiopulmonary criteria donated the organ．The liver graft weight was 598 g and the warm ischemic time was 10 min. The liver donor was transplanted to a 64-year-old woman，the graft to recipient weight ratio was 1.09%，the graft volume/estimated standard liver volume was 61.8%．The classic orthotopic liver transplantation without bypass was underwent，the postoperative recovery was smooth after the liver transplantation．The CT scan showed that the liver graft volume was 1 003cm3 on day 14 after operation．The patient was discharged on 45 d after orthotopic liver transplantation and the liver function was normal when followed-up 3 months after the operation. Conclusions Pediatric donation after cardiac death liver graft can be successfully utilized to adult recipient．Recipient selection and surgical approach should be decided by conditions of both donor and graft．
The quality of a donor liver after cardiac death is closely associated with energy metabolism during preservation. Ex vivo mechanical perfusion has broad application prospects because this technique can help energy metabolism and repair ischemia injury of donors′ livers. Some core issues are presented in this review in order to provide references for propelling secure application of liver transplantation based on donation after cardiac death.
