Free hepatic vein pressure (FHVP) was measured using an 8F polyethylene catheter with a multiperforated distal end, which was positioned in the graft's right hepatic vein during ex situ preparation on the back table. The proximal end of this catheter was exteriorized in the infrahepatic portion of IVC. In the conventional group, exteriorization was performed through the anastomosis suture. In the piggyback group, IVC was ligated around the catheter. Central venous pressure (CVP) was obtained using a Swan-Ganz catheter (routine procedure). Measurement of hepatic vein and right atrium pressure was made once, after concluding biliary anastomosis.
