Lung transplantation with donation after cardiac death donors: long-term follow-up in a single center.

We sought to examine long-term outcomes at the University of Wisconsin for all lung transplant recipients who received lungs from donation after cardiac death donors since the initiation of this program in 1993. Eighteen (4.2%) of the 424 lung transplantations performed in 406 patients between January 1993 and April 2009 used lungs from donation after cardiac death donors. Outcomes for this recipient cohort were compared with those for recipients who received organs from brain-dead donors. Warm ischemic time (from withdrawal of support to reperfusion of organs) was 30 +/- 17 minutes (11-93 minutes). The patient survival rates in the donation after cardiac death group (DCD group) at 1, 3, and 5 years were 88.1% +/- 7.9%, 81.9% +/- 9.5%, and 81.9% +/- 9.5%, respectively. These survival rates were not different from those of the brain-dead donor group (BDD group, P = .66). The incidence of primary graft dysfunction in the DCD group was similar to that of the BDD group (P = .59). However, the incidence of airway complications was somewhat higher in the DCD group. Freedom from bronchiolitis obliterans syndrome at 1, 3, and 5 years in the DCD group was 80.4% +/- 10.2%, 80.4% +/- 10.2%, and 72.3% +/- 11.9%, respectively, and did not differ from the incidence of bronchiolitis obliterans syndrome in the BDD group (P = .59). Our data show that the long-term patient and graft survival rates after donation after cardiac death lung transplantation were equivalent to those after brain-dead donor lung transplantation. Our findings suggest that the use of donation after cardiac death donors can safely and substantially expand the donor pool for lung transplantation.

Liver transplantation following donation after cardiac death: an analysis using matched pairs.

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. Between January 2002 and April 2008, 39 DCD grafts were transplanted. These were matched with 39 DBD recipients on the basis of identified variables that had a significant impact on mortality. These were used to individually match DCD and DBD patients with similar predictive mortality. We compared patient/graft survival, primary non-function (PNF), and rates of complications. Of all liver transplants, 6.1% were DCD grafts. PNF occurred twice in the DCD group. The incidence of nonanastomotic biliary strictures (NABS; 20.5% versus 0%, P = 0.005) and hepatic artery stenosis (HAS; 12.8% versus 0%, P = 0.027) in the DCD group was higher. One-year (79.5% versus 97.4%, P = 0.029) and 3-year (63.6% versus 97.4%, P = 0.001) graft survival was lower in the DCD group. Three-year patient survival was also lower (68.2% versus 100%, P < 0.0001). Our study is the first to use case-matched patients and compare groups with similar predictive mortality. There was a higher incidence of NABS and HAS in the DCD group. NABS were likely a result of warm ischemia. 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.

Medium-term outcome after lung transplantation is comparable between brain-dead and cardiac-dead donors.

Donation after cardiac death (DCD) to overcome the donor organ shortage is now moving into the clinical setting, but the medium-term outcome after DCD lung transplantation (LTx) remains largely unknown. In this retrospective study, DCD LTx recipients (n = 21) were compared with a cohort of donation-after-brain-death (DBD) LTx recipients (n = 154) transplanted between February 2007 and July 2010. Immediate (post)operative outcome was evaluated by assessing need for peri-operative extracorporeal membrane oxygenation (ECMO), time to extubation, hospital discharge and primary graft dysfunction (PGD) within the first 48 hours. Survival, incidence of bronchiolitis obliterans syndrome (BOS), acute rejection (AR) and inflammatory markers in blood and in bronchoalveolar lavage (BAL) were assessed and compared over a median follow-up of 327 days for DCD and 531 days for DBD, showing no statistically significant difference (NS). There were no differences between groups with regard to patient characteristics except for a higher number of patients transplanted for obliterative bronchiolitis in the DCD group (4 of 21 vs 7 of 154; p < 0.05). In the DCD group, 2 of 21 patients died, vs 23 of 154 patients in the DBD group (NS). Actuarial survival rates at 6 months, 1 year and 3 years are 95%, 95% and 71% for the DCD group and 96%, 91% and 75% for the DBD group (NS). Three patients (14%) in the DCD group developed BOS vs 15 patients (10%) in the DBD group (NS). Survival and freedom from BOS were not different between the groups. AR, inflammatory markers and immediate (post)operative outcome also did not differ. In our experience, both early- and medium-term outcome in DCD lung recipients is comparable to that of DBD lung recipients. Use of lungs recovered from controlled donors after cardiac death is a safe option for expansion of the donor pool.
