Liver transplant donation after cardiac death: experience at the University of Liege

Abstract

Objective: Donation after cardiac death (DCD) has been proposed to overcome in part the organ donor shortage. In liver transplantation, the additional warm ischemia time associated with DCD procurement may promote higher rates of primary nonfunction and ischemic biliary lesions. We reviewed the results of liver transplantation from DCD.

Patients and methods: From 2003 to 2007, we consecutively performed 13 controlled DCD liver transplantations. The medical records of all donors and recipients were retrospectively reviewed, evaluating in particular the outcome and occurrence of biliary complications. Mean follow-up was 25 months.

Results: Mean donor age was 51 years, and mean intensive care unit stay was 5.4 days. Mean time between ventilation arrest and cardiac arrest was 9.3 minutes. Mean time between cardiac arrest and arterial flushing was 7.7 minutes. No-touch period was 2 to 5 minutes. Mean graft cold ischemia time was 295 minutes, and mean suture warm ischemia time was 38 minutes. Postoperatively, there was no primary nonfunction. Mean peak transaminase level was 2546 UI/mL. Patient and graft survival was 100% at 1 year. Two of 13 patients (15%) developed main bile duct stenosis and underwent endoscopic management of the graft. No patient developed symptomatic intrahepatic bile duct strictures or needed a second transplantation.

Conclusions: Our experience confirms that controlled DCD donors may be a valuable source of transplantable liver grafts in cases of short warm ischemia at procurement and minimal cold ischemia time.
