The ligamentum venosum divides which lobes of the liver?

The ligamentum venosum is a fibrous remnant of the umbilical vein and serves an important role in anatomy by marking the boundary between the caudate lobe and the left lobe of the liver. In terms of liver anatomy, the caudate lobe is situated posteriorly and is somewhat separate from the left lobe, which is largely anterior. The presence of the ligamentum venosum indicates this division, helping to differentiate the two lobes during imaging and surgical approaches.

Understanding this anatomical boundary is crucial for interpreting liver ultrasound and other imaging studies, where knowing the precise lobular anatomy can influence diagnosis and treatment options. The distinct liver segments have different vascular and biliary supplies, and this anatomical knowledge can assist in targeted interventions as well.
