[LIVER ORTHOTOPIC TRANSPLANTATION IN EXPERIMENTAL ANIMALS WITH VENO-VENOUS BYPASS PUMP HOSPITAL NACIONAL EDGARDO REBAGLIATI MARTINS-HNERM- 09/1996 TO 07/1998].

This study was carried at at the Hospital Nacional Edgardo Rebagliati Martins, from September 1996 to July 1998. 61 surgical procedures were performed in experimental animals, 39 in dogs and 22 in pigs. During the anhepatic phase, we used veno-venous bypass with centrifugal pumps and without systemic anticoagulation drugs in 6 animals, and passive venovenous bypass with systemic anticoagulation drugs in 8 animals. Experimental animals were sacrified two hours after the procedures were concluded in order to assess the status of vascular anastomosis and thrombus formation.
