title: Split-liver transplantation in the high-MELD adult patient: are we being too cautious?
abstract: The fear that patients with high-mathematical model for end stage liver disease (MELD) score may not be suitable candidates for segmental grafts because of their need for greater liver mass has continued to push the transplant community toward the use of whole LT (WLT) in preference to split LT (SLT). In order to define the outcome of segmental liver transplantation in a better manner in high-MELD patients (score > or =26), we queried the UNOS registry for graft and patient survival results according to MELD score in adult patients receiving WLT and SLT in the United States from the inception of MELD allocation (February 27, 2002) through March 9, 2007. A total of 316 adult patients received a SLT as compared with 20 778 WLTs. Patient and graft survival rates at 6 and 12 months were comparable for all MELD ranges, including the 'high-MELD' recipients (e.g. at MELD score 31-35, patients' and grafts' survival rates at 12 months was 87.5% in SLT group vs. 84.4% and 76.7% in WLT group respectively). The results even at higher MELD scores (i.e. >35) were more than acceptable. In conclusion, patient and graft survival rates for SLT in high-MELD adult patients are comparable to the same for WLT.
