Outcomes of Liver Transplant With Donors Over 70 Years of Age

Abstract

Organ shortage has forced transplant teams to progressively expand the acceptance of marginal donors. MethodsWe performed a comparative analysis of the post-transplant evolution depending on donor age (group I: less than 70 years old (n=474) vs group II: 70 or more years old [n=105]) over a 10 year period (2002–2011). ResultsDonors over 70 years old were similar to donors less than 70 years old in terms of ICU stay, gender, weight, laboratory results, and use of vasoactive drugs. However, the younger donor group presented with cardiac arrest more often (GI: 14 vs GII: 3%, P=.005). There were no differences in initial poor function (GI: 6% vs GII: 7.7%; P=.71), ICU stay (GI: 2.7±2 vs GII: 3.3±3.8, P=.46), hospital stay (GI: 13.5±10 vs GII: 15.5±11, P=.1), or hospital mortality (GI: 5.3 vs GII: 5.8%, P=.66) between receptors of more or less than 70 year old grafts. After a median follow up of 32 months, no differences were found in the incidence of biliary tract complications (GI: 17 vs GII: 20%, P=.4) or vascular complications (GI: 11 vs GII: 9%, P=.69). The actuarial 5 year survival was similar for both study groups (GI: 70 vs GII: 76%, P=.54). ConclusionsIn our experience, the use of grafts from donors older than 70 years, when other risk factors are avoided (cold ischaemia, steatosis, sodium levels), does not worsen the results of liver transplantation on the short or long term.
