title: Marginal donors in liver transplantation.
abstract: Marginal liver donor criteria included the following: obesity (weight >100 Kg or BMI >27), age >50 years; macrovesicular steatosis >50%; intensive care unit stay >4 days; prolonged hypotensive episodes of >1 hour, and <60 mm Hg with high inotropic drug use (dopamine, [DPM] > 14 microg/kg per minute); cold ischemia time >14 hours, peak serum sodium >155 mEq/L; sepsis, viral infections, and alcoholism; high levels of bilirubin, ALT, and AST, or extrahepatic neoplasia. Between August 1992 and May 2003, we performed 251 liver transplants in 241 patients of whom 155 are presently alive. We used 124 (49.4%) standard donors and 127 (50.6%) marginal donors. Among the group that received a standard donor, 81 (65.3%) are still alive. Among recipients of organs from marginal donors. 81 (63.8%) are still alive. We also assessed the quality of donors according to the severity of recipient disease. For standard donors these outcomes were 61.5% for UNOS 1, 37.5% for UNOS 2A, 73.2% for UNOS 2B, and 80% for UNOS 3 for marginal donors they were 46.1% for UNOS 1, 53.6% for UNOS 2A, 70.7% for UNOS 2B, and 63.6% for UNOS 3. Among the patients who received a liver from a donor >60 years old, there were no survivors in UNOS 1 and 2A, but there were good results in groups 2B and 3. These results suggest there is no difference between marginal and standard donors, even in sick patients, with the exception of donor age.
