RESUMO
<p><b>OBJECTIVE</b>To evaluate the efficacy and timing of re-transplantation for hepatic artery complications after orthotopic liver transplantation.</p><p><b>METHODS</b>Between December 2003 and December 2006, the clinical data of 13 patients diagnosed as hepatic artery complications after liver transplantation were retrospectively analyzed.</p><p><b>RESULTS</b>There were no significant difference in duration of operation and anhepatic phase between the initial transplantation and the second transplantation (P = 0.291, P = 0.312). However, intra-operative blood loss [(3.1 +/- 1.1) L vs. (1.5 +/- 0.9) L, P = 0.005] and intensive care unit stays [(4.3 +/- 1.8) d vs. (3.2 +/- 2.5) d, P = 0.015] were significantly increased in the re-transplant patients. No perioperative mortality occurred. The postoperative mortality of liver re-transplantation was 38.5% (5/13) including acute renal failure in two patients, severe infection in two and heart infarction in one. The other 8 patients were followed from 6 months to 51 months, with a median survival time of 22.5 months.</p><p><b>CONCLUSIONS</b>Liver re-transplantation is the only viable option for patients with irreversible graft dysfunction secondary to hepatic artery complications after liver transplantation. Proper indication and optimum time of re-transplantation, reasonable individual immunosuppression regime and effective perioperative care program contribute to the increase of the survival rate of the patients performed liver re-transplantation.</p>
