[Preservation of donor livers with University of Wisconsin solution].

The University of Wisconsin-solution extends the cold storage time of liver grafts over 20 hours. The early function is equal or better than with Eurocollins solution. Due to the extended preservation time, logistical advantages are present. However, deliberate extension of cold ischemia over the limit of 20 to 24 hours seems not yet indicated, since primary non-functioning grafts have a higher incidence after extended preservation.
