Selective Clamping of Segmental Branches Figs 520 to 523
In patients with severe liver cirrhosis, alternate selective clamping of the segmental branches must be done during the dissection, to reduce liver damage and prevent congestion of the portal system. During the dissection between the middle and left segments, the left segmental branch of the Glissonean pedicle must be temporarily clamped, instead of using the Pringle maneuver. Likewise, at the time of dissection on the intersegmental plane between the middle and right segments, the right segmental branch must be clamped. In right segment or left segment resection, this selective clamping of the neighboring branch may be beneficial (Fig. 5.24).
