"The arrangement of structures around the porta hepatis can be described by the letter "H". The left limb of the "H" is formed by ligamentum venosum superiorly and ligamentum teres inferiorly. Meanwhile, the right limb is formed by the inferior vena cava (IVC) superiorly and the gallbladder inferiorly. The crossbar of the letter "H" is the porta hepatis where the bile ducts, hepatic arteries, and portal vein enters and exits the region. There are also some nerves and lymphatics in the porta hepatis 5. The area bounded between the gallbladder and ligamentum teres is the quadrate lobe of the liver while the area bound between ligamentum venosum and IVC is the caudate lobe of the liver 5."
