Abstract: Objective To learn the clinical outcomes of hepatic artery bypass reconstruction of liver transplantation (LT) using allogenic iliac artery on special occasions. Methods The clinical data of 427 patients who received LT from 2004 to 2010 in our liver transplantation center were reviewed retrospectively and the methods and clinical outcomes of hepatic artery bypass reconstruction of LT using allogenic iliac artery were analyzed. Results Hepatic artery bypass reconstruction were successfully performed 13 times in 12 cases by using allogenic iliac artery; 11 times were allogenic iliac artery-recipient’s abdominal aorta bypass, 1 time was allogenic iliac artery-recipient’s splenetic artery bypass,1 time was allogenic iliac artery-recipient’s left common iliac artery bypass; 4 times of hepatic artery bypass reconstruction were performed because of the second LT, 9 times of the reconstruction were performed because of useless of recipients’ hepatic artery (including one living donor LT, LDLT). Time consumption of hepatic artery bypass construction was ranged from 90 to 120 minutes. The grafts survival time was (511.8±573.9) days (range from 2 to 1 577 days, median 270 days), the recipients survival time was (554.5±606.1) days (range from 2 to 1 577days, median time 317 days). There were no complications related to hepatic artery bypass reconstruction in the follow-up period. Conclusion Hepatic artery bypass reconstruction of LT using allogenic iliac artery on special occasions is a safe and effective method, but the preexisting comorbidities and poor situations of recipient may lead to poor survival after LT.
