Objective To explore the methods of hepatic artery reconst ruction with iliac arterial interpositiongraf t in orthotopic liver t ransplantation (OL T) and influential factor of relevant complications postoperatively.Methods Analyzed ret rospectively 8 OL T , the hepatic artery reconst ruction with arterial inflow based on recipientinf rarenal aorta using donor iliac artery graf t tunneled through the t ransverse mesocolon and pancreas. Results Thetime required for hepatic artery reconst ruction with iliac arterial interposition graf t was 52 - 126 minutes. Amongthe 8 patient s , 2 patient s developed postoperative bililary t ract complications , 1 with biliary fistula , 1 with int rahepatic biloma , the others were recovered smoothly and liver function returned to normal about one week af ter livert ransplantation. No complications of hepatic artery were observed. Conclusion Iliac arterial interpositional graft is aneffective and reliable method of revascularization in liver transplantation when the use of hepatic artery is not possible.
