Fig. 4

Isolating the hepatic vein with Laennec’s approach for LAH Laennec’s capsule and the middle hepatic vein are shown by H&E staining (a-d). (a) and (b) depict the venous onset and terminal at 20× magnification. (c) and (d) show a higher magnification view of the square in (a) and (b). Representative views during isolation of the hepatic vein are shown of the middle hepatic veins and their trunks during a right hepatectomy (e and f), in which Laennec’s capsule was located according to the elliptical shadow. Representative views during isolation of the right hepatic vein and its trunk are shown during a right posterior hepatectomy, in which Laennec’s capsule was located according to the elliptical shadow (g). The contour for the right hepatic vein is marked with a red line (h).
