The fissure for the ligamentum venosum on the visceral surface of the liver forms the boundary between the left lobe and the caudate lobe. The ligamentum venosum itself is the fibrous remnant of the fetal ductus venosus, and its groove on the liver’s interior surface creates a distinct separation between these two lobes. The caudate lobe sits posteriorly near the IVC, while the left lobe lies more anterolaterally, and the fissure runs between them, making this the correct anatomical boundary.
