ObjectiveTo explore the application of extracorporeal venovenous bypass in orthotopic liver transplantation in pigs and to compare hemodynamic changes during operation of two different bypass ways. MethodsTwentyfive porcine orthotopic liver transplantations were performed and extracorporeal venovenous 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.ResultsFourteen 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＜0.05).ConclusionApplying venovenous bypass may stabilize recipients’ hemodynamics in porcines orthotopic liver transplantation,and splenic vein draining way has more advantages than portal vein.
