The liver is divided into the right and left lobes by the main lobar fissure. The right lobe is further divided into an anterior and a posterior segment, and the left lobe is divided into a medial and a lateral segment. The main lobar fissure is in a plane which can be approximated by drawing a line connecting the gallbladder bed and the inferior vena cava (Cantlie line). The middle hepatic vein courses within the main lobar fissure. The right hepatic vein runs between the anterior and the posterior segments of the right lobe. The falciform ligament, which contains the ligamentum teres, separates the medial from the lateral segment of the left lobe.
