Figures 2-5. (2) Recumbent H view of the left portal vein bifurcation. On a subcostal US scan, the left portal vein (p), the ascending branch of the left portal vein (a), and the branches to three segments of the left lobe of the liver (2, 3, and 4) suggest a recumbent H. (3) Recumbent H view of the right portal vein bifurcation. Intercostal oblique US scan shows the branches to the anterior (5 and 8) and posterior (6 and 7) segments of the right lobe of the liver. rpv = right portal vein. (4) Hepatoduodenal ligament view. Sagittal US scan shows the common hepatic duct and common bile duct (CBD) anterior to the main portal vein (MPV). (5) Pancreatic head view. Transverse US scan shows the common bile duct (arrow) along the posterolateral aspect of the pancreatic head. The gastroduodenal artery (arrowhead) courses along the anterolateral aspect of the pancreatic head. PV = portal vein, SV = splenic vein.
