Diagnostic Ultrasound - Abdomen and Pelvis
Pancreas PANCREAS IN SITU Anatomy: Abdomen Stomach (cut & removed) Spleen Gastroduodenal artery Superior (dorsal) pancreatic artery Splenic artery Great pancreatic artery Posterior superior pancreaticoduodenal artery Anterior superior pancreaticoduodenal artery Base of transverse mesocolon Duodenum Transverse colon Duodeno-jejunal junction Superior mesenteric artery & vein Base of small bowel mesentery Graphic shows the arterial supply to the body & tail of the pancreas through terminal branches of the splenic artery, which are variable in number & size. The two largest are usually the dorsal (superior) and great pancreatic arteries, which arise from the proximal & distal splenic artery, respectively. The arteries to the pancreatic head and duodenum come from the pancreaticoduodenal arcades that receive flow from the celiac and superior mesenteric arteries. The superior mesenteric vessels pass behind the neck of the pancreas and in front of the third portion of the duodenum. The root of the transverse mesocolon and small bowel mesentery arise from the surface of the pancreas and transmit the blood vessels to the small bowel & transverse colon. The splenic vein runs along the dorsal surface of the pancreas. The splenic vessels and pancreatic tail insert into the splenic hilum. 39

Anatomically, the pancreatic axis from head to tail is directed superiorly and to the left. This lower transverse section demonstrates the bulk of the pancreatic head. (Middle) Transverse transabdominal grayscale ultrasound at the epigastrium is shown, slightly higher than the previous image. Note that the pancreatic body and tail have now come into view. (Bottom) Oblique transabdominal grayscale ultrasound at the epigastrium is shown. The transducer is tilted slightly cranially and laterally to the left to follow the pancreatic axis, thus imaging the pancreas in its entirety. The splenic vein courses along the posterior pancreas and provides an excellent landmark in locating the pancreas. The superior mesenteric artery is more posteriorly located and has a characteristic dot shape as it is imaged end-on. 40
