title: Ex vivo extended left hepatectomy with caval preservation, temporary portacaval shunt, and reconstruction of the right hepatic vein outflow using a reversed portal vein bifurcation graft.
abstract: Liver resections that require ex vivo techniques occur rarely, but when done are generally performed on veno-veno bypass to maintain venous return and decompress the portal circulation during the anhepatic phase of the procedure. We describe an ex vivo extended left hepatectomy that was performed with preservation of the inferior vena cava and the use of a temporary portacaval shunt to eliminate the need for veno-venous bypass. Ex vivo resection allowed reconstruction of right hepatic vein branches, using the patient's reversed portal vein bifurcation as a graft to provide venous outflow.
