ABSTRACT
Objective To explore the application of extracorporeal veno venous bypass in orthotopic liver transplantation in pigs and to compare hemodynamic changes during operation of two different bypass ways. Methods Twenty five porcine orthotopic liver transplantations were performed and extracorporeal veno venous bypass was established during anhepatic phase through a catheter in portal vein (group A, n =16) or in splenic vein (group B, n =9).Hemodynamic changes were monitored continuously.Results Fourteen recipients survived two days after operation (14/16) in group A while all survived in group B (9/9).Transient hemodynamic disturbance (MAP and CVP decreased,and HR increased) was monitored at both the beginning and the end of anhepatic stage in group A,while these parameters kept stable in group B ( P
