Figure 8: (a) Portal vein and inferior vena cava-both posterior structures, are seen on opposite side of the duodenal lumen. The inferior vena cava is seen in long axis on the right side of the screen. See the schematic depiction [Figure 8] to understand this orientation. The duodenal folds converge at the bottom of the screen. 1: Portal vein trunk; 2: Descending duodenal lumen; 3: Inferior vena cava; 4: Right atrium. (b) The portal vein and inferior vena cava are seen in cross-section from the duodenum. 1: Portal vein; 2: Inferior vena cava; 3: Descending duodenal lumen. (c) The inferior vena cava is displayed in long axis on the left side of the screen unlike the previous images. The descending duodenum is seen in the midline below the probe. 1: Inferior vena cava; 2: Descending duodenum
