Risk factors for graft dysfunction after adult-to-adult living donor liver transplantation.
The aim of this study was to investigate the risk factors for graft dysfunction after adult-to-adult living donor liver transplantation (LDLT). Thirty-nine adults with chronic cirrhosis underwent LDLT between 1999 and 2004. Their postoperative courses were uneventful with no vascular or bile duct complications early after LDLT, except one mild hepatic artery stenosis. The preoperative MELD scores were significantly higher in the failed graft group (n=5) than the functioning graft group (n=34; P=.004), while the graft liver weight/standard liver volume ratio was similar between these groups. We concluded that a high preoperative MELD score was associated with postoperative graft failure and that graft size had little impact on graft outcome. Although large grafts would seem intuitively more suitable for sick recipients, we did not show a benefit among this cohort; the MELD score was the best predictor, a finding that is also most consistent with donor safety.
