Comparative Study
Liver transplantation using controlled donation after cardiac death donors: an analysis of a large single-center experience.
The use of donation after cardiac death (DCD) donors may provide a valuable source of organs for liver transplantation. Concerns regarding primary nonfunction (PNF) and intrahepatic biliary stricture (IHBSs) have limited the enthusiasm for their use. A retrospective analysis of 1436 consecutive deceased donor liver transplants performed between December 1998 and October 2006 was conducted. ⋯ Patient survival and graft survival were not significantly different between DCD donors less than 60 years old, DCD donors greater than 60 years old, and DBD donors. Causes of graft loss included IHBSs (n = 9), PNF (n = 4), recurrent hepatitis C virus (n = 4), hepatic artery thrombosis (n = 1), rejection (n = 2), and patient death (n = 13). Contrary to previously published data, excellent long-term patient survival and graft survival can be obtained with DCD allografts, and in our experience, they are equivalent to those obtained from DBD allografts.

This study assesses the relation between the anhepatic phase duration and the outcome after liver transplantation. Of 645 patients who underwent transplantation between 1994 and 2006, 194 were recipients of consecutive adult primary piggyback liver transplants using heart-beating donors. The anhepatic phase was defined as the time from the physical removal of the liver from the recipient to recirculation of the graft. ⋯ A direct relation between the anhepatic phase duration and patient survival could, however, not be established. In conclusion, this study shows that liver transplant patients with an anhepatic phase over 100 minutes have a higher incidence of graft dysfunction. Patients with graft dysfunction have significantly worse 1-year patient survival.

Grafts from donation after cardiac death (DCD) donors are used to increase the number of organs available for liver transplantation. There is concern that warm ischemia may impair graft function. We compared our DCD recipients with a case-matched group of donation after brain death (DBD) recipients. ⋯ HAS may have been due to ischemia or arterial injury during retrieval. The DCD group had significantly poorer outcomes, but DCD grafts remain a valuable resource. With careful donor/recipient selection, minimization of ischemia, and good postoperative care, acceptable results can be achieved.

Optimal measures for the prevention of cytomegalovirus (CMV) in high-risk orthotopic liver transplant (OLT) patients are unknown. The charts of high-risk OLT recipients with 12 months of follow-up who were transplanted over a 44-month period were reviewed. The incidence of CMV disease in CMV-seropositive donor/CMV-seronegative recipient patients receiving valganciclovir or ganciclovir prophylaxis was compared. ⋯ In conclusion, late-onset CMV disease occurred more frequently among high-risk liver transplant recipients treated with valganciclovir prophylaxis. The 4-fold higher incidence of CMV disease in our study supports the avoidance of valganciclovir for prophylaxis in high-risk OLT patients. Liver Transpl 15:963-967, 2009. (c) 2009 AASLD.

Familial amyloidotic polyneuropathy (FAP) patients present adrenergic cardiac input blockade secondary to amyloid deposits and sympathetic neuropathy. Consequently, their capacity to compensate for hemodynamic changes is limited. To avoid hemodynamic disturbances in sequential liver transplants, a standard procedure with venovenous bypass or inferior vena cava preservation is contemplated. ⋯ During the postoperative period, the incidence of minor cardiovascular events, incidence of acute renal dysfunction, and outcomes were similar in the 2 groups. In conclusion, either preservation of the vena cava or the standard technique with venovenous bypass can be safely used in FAP patients during liver transplantation. Liver Transpl 15:869-875, 2009.
