Abstract:
Objective To describe the hemodynamic changes during piggyback liver transplantation (PBLT), and to analyze the hemodynamic correlation with various degrees of cirrhosis according to Childpugh classification. Methods Between March 1999 and June 2004, 180 patients underwent PBLT procedure in our institution, and 95 cases were selected and divided according to Child classification. The intraoperative hemodynamics of different time points were retrospectively analyzed, including mean artery pressure (MAP), heart rate (HR), central vein pressure (CVP) and mean pulmonary artery pressure (MPAP). Results Hemodynamic changes were minimal before and during anhepatic phase in all the patients. At reperfusion, a hemodynamic disturbance occurred featured by decrease of MAP and increase of MPAP. Comparison between different Child class showed that in the Child C group, MAP were lower and HR were higher before new liver phase, while CVP and MPAP were higher during new liver phase. Conclusion Hemodynamic changes were minimal before and during anhepatic phase for PBLT, while they were more severe during reperfusion, and they also correlates with the different Child class before transplantation. The more severe of the cirrhosis before transplantation according to Child classification, the greater hemodynamic changes during the operation.
