Dissection of the Liver Parenchyma

There are two margins of the area which are demarcated for dissection, one between the left and middle segment and one between the middle and right segment. Dissection should be done on both demarcated margin lines. During the dissection of the liver parenchyma, bleeding should be controlled by the Pringle maneuver, and by IVC clamping.

While these margins are cut, the middle hepatic vein and the right hepatic vein should be intact on their remaining sides. Next, the dissection proceeds into the liver until the imaginary line AB (see Fig. 2.5) is reached.

During the dissection of the liver parenchyma, there are no small branches of the Glissonean pedicle, but only branches of the hepatic vein across the cut surface (Figs. 5.17 to 5.19).
