Stepwise evaluation of liver sectors and liver segments by endoscopic ultrasound

Figure 12 The caudate lobe, its boundaries, and its relationships. A: The exit of the inferior vena cava from the liver demarcates the lowest limit of the posterior border. The right kidney is seen through the inferior vena cava. Segment VI lies above the right kidney; B: The left border of the caudate lobe lies close to superior recess of the lesser sac, which is filled with fluid in this case; C: The vascular supply of the caudate lobe from the right branch of the portal vein. The right and left lobes of the liver lie on either side of the right and left sagittal fissures, and the caudate and quadrate lobes lie posterior and anterior to the transverse fissure. RK: Right kidney; IVC: Inferior vena cava; PV: Portal vein.
