[One liver for 2 transplantation recipients. How to divide the portal pedicle?].

It is possible to obtain two hepatic transplants from a single cadaveric liver by separation or right and left livers or by separation of the right lobe from the left lobe medial to the umbilical cleft. We attempt to define the ideal basis of separation of the structures of the portal pedicle, based on anatomical study of 25 livers. One should ideally section the left portal vein, the right branch of the hepatic artery, the left hepatic duct. The segment I must be systematically resected, the segment IV must be resected after a separation of the right lobe from the left lobe. A cholangiogram and an arteriogram are indispensable prior to hepatic division.
