image Describe the relationship of the CBD, pancreatic duct, ampulla of Vater and duodenum.

image Visualize cross-sectional relationships of the pancreatic head.

Figure 30-1


Connect the orange dots of the main pancreatic duct; note that it, too, enters the duodenum at the ampulla of Vater.




Clinical Correlates



image Small tumors of the pancreatic head may cause CBD obstruction.

image Gallstones passing through the CBD may cause pancreatitis.

image Chronic pancreatitis can cause a stricture of the distal CBD.

image The cross-sectional anatomy in Figure 30-2 represents an axial CT section near the inferior border of the pancreas.

image Note the circular densities—SMA, SMV, aorta, and IVC. The compressible IVC may often appear ovoid.
