Liver transplantation in recipients over 65 yr old: a single center experience

The advanced age of the recipient is considered a "relative contraindication" to liver transplantation (LT). However, recently some studies reported a morbidity rate and an overall survival comparable with those of younger patients. Here, we reported the outcome after LT in recipients aged >65 yr.

Between January 2000 and December 2006, 565 LT was performed in 502 recipients in our institution. Of these, 34 were recipients of >65 yr old (aged group). We focused our study comparing: donor age, co-morbidities, model for end-stage liver disease (MELD) and American Society of Anesthesiologists (ASA) score, duration of operation, transfusions and outcome between the two groups (young/aged).

For the group aged >65: the mean donor age was 52.5 (range 16-75) yr and the graft weight 1339 g (890-1880 g). Co-morbidity was recorded in 25 (73.5%), coronary artery disease (CAD) in 17 (50%), diabetes mellitus (DM) and chronic renal insufficiency in four (11.7%) and chronic obstructive pulmonary disease (COPD) in three patients (8.8%). Mean MELD score was 14.9 (range 12-29) and ASA score was two in 15 (44.1%); and three in 19 (55.8%) recipients. Mean operation time was four h 45 min, three patients also received combined kidney transplantation. Twenty-five (73.5%) recipients received blood transfusions (mean 3.2). Morbidity was observed in 20 patients (58.8%); of these two had hepatic artery thrombosis requiring re-LT. Overall survival was 80% (40 months of follow-up), in particularly, at 30-d, one yr, three yr was 91%, 84%, 80%, respectively. The only two statistical differences reported (p = 0.02) are: the lower rate of CAD in the younger group of recipients (12%), compared with the aged group (50%) and the subsequently lower mortality rate secondary to cardiac causes in the younger group (1.4%) compared with aged group (8.8%).

Our results suggest that the recipient age should not be considered an absolute contraindication for LT when the graft/recipient matching is optimal and when an adequate cardiac assessment is performed.
