Figure 2. Three-dimensional MIP image from CT data demonstrates the hepatic venous confluence in which the left hepatic vein (LHV) (solid arrow) and middle hepatic vein (MHV) (open arrow) form a common trunk extrahepatically before joining to form the inferior vena cava (IVC). This configuration is important in left lateral resection, since the surgeon can simply clamp the LHV extrahepatically and then secure the venous drainage to the graft. The MHV is secured to preserve the venous drainage of segment IV.
