Which structure is NOT contained in the left intersegmental fissure?

• A. Right hepatic vein
• B. Left hepatic vein
• C. Falciform ligament
• D. Ligamentum teres

Answer: (A)

The left intersegmental fissure corresponds to the boundary that contains left-lobe drainage and its landmarks. It carries structures such as the left hepatic vein as it courses toward the IVC, and it is associated with the falciform ligament and the ligamentum teres that lie in or near this boundary. The right hepatic vein, however, drains the right lobe and travels on the right side of the liver, not within the left intersegmental fissure. Therefore, the structure not contained in the left intersegmental fissure is the right hepatic vein.
