This retrospective, case-controlled study compared the outcome of 17 OLTs (group A) using livers donated by subjects over 70 years of age with 17 OLTs (group B) with livers from donors under 40. Clinical data were used form the period 1996-1998. The following variables were considered in the analysis: donor clinical and laboratory parameters, cold ischemic periods, intra-operative blood and plasma replacement, 30-day mortality rate, incidence of primary graft dysfunction, acute rejection and arterial complication and long term survival. The main post-operative parameters were also included. Liver biopsy, performed in 9/17 of group A, revealed minimal steatosis. There were 2 post-operative deaths in group A and 1 in group B (p = NS). Two arterial complications were observed in group A (p = NS) and only one patient required retransplantation (p = NS). The only other difference found among clinical variables was the amount of total bilirubin at post-operative days 8 and 10, aPTT at days 6 and 13 and albumin at days 5 and 6. A two-year follow-up showed survival rates to be 88.2% and 94.1% for groups A and B, respectively (p = NS). Candidates over 70 years of age should be excluded as liver donors. In such cases, greater care needs to be placed on pathological vascular conditions related to advanced stage atherosclerosis such as calcified plaques on the hepatic artery, a possible factor in severe postoperative complications.

Abstract

This retrospective, case-controlled study compared the outcome of 17 OLTs (group A) using livers donated by subjects over 70 years of age with 17 OLTs (group B) with livers from donors under 40. Clinical data were used form the period 1996-1998. The following variables were considered in the analysis: donor clinical and laboratory parameters, cold ischemic periods, intra-operative blood and plasma replacement, 30-day mortality rate, incidence of primary graft dysfunction, acute rejection and arterial complication and long term survival. The main post-operative parameters were also included. Liver biopsy, performed in 9/17 of group A, revealed minimal steatosis. There were 2 post-operative deaths in group A and 1 in group B (p = NS). Two arterial complications were observed in group A (p = NS) and only one patient required retransplantation (p = NS). The only other difference found among clinical variables was the amount of total bilirubin at post-operative days 8 and 10, aPTT at days 6 and 13 and albumin at days 5 and 6. A two-year follow-up showed survival rates to be 88.2% and 94.1% for groups A and B, respectively (p = NS). Candidates over 70 years of age should be excluded as liver donors. In such cases, greater care needs to be placed on pathological vascular conditions related to advanced stage atherosclerosis such as calcified plaques on the hepatic artery, a possible factor in severe postoperative complications.
