Coeliac trunk territory
Product code: HP0413
-
Whole Whole region / system / unpaired organ.
The coeliac trunk supplies the foregut-derived region of the gastrointestinal canal (tract), from the inferior part of the oesophagus to the descending part of the duodenum. This pattern of arterial perfusion directly informs the regional pattern of lymphatic and venous drainage, sympathetic innervation and visceral pain, and the location of portosystemic venous anastomoses. This Silicone Plastinate reveals the origin, course and branching of the coeliac trunk and its main branches, alongside their target viscera and key anatomical relations. Various organs and vessels of the retroperitoneal space can also be explored, including the relationship of the superior mesenteric artery and vein with the pancreas and duodenum.

Key features include
General
- Inferior part of posterior thoracic wall and posterior abdominal wall, to around L3.
- Gastrointestinal canal, from oesophagus to duodenojejunal flexure.
Thorax
- Transverse section through the inferior part of the thorax, revealing the vertebral column and associated muscles, and the spinal cord with its meningeal coverings in the vertebral canal.
- Diaphragm (anterior part removed), showing part of its central tendon.
- Relationship of the oesophagus with the right crus of the diaphragm and the inferior phrenic arteries.
- Descending thoracic aorta, oesophagus and inferior vena cava passing through their associated foramen/hiatus (apertures) in the diaphragm.
- Superior view of the lateral and posterior parts of the costodiaphragmatic recesses.
- Position and fibre orientation of the intercostal muscles and muscles of the anterolateral abdominal wall.
- Course and tissue layer location of the intercostal nerves and arteries.
- Various thoracic splanchnic nerves.
Abdomen
- Gastrointestinal canal, from oesophagus to duodenojejunal flexure.
- Most parietal peritoneum and peritoneal formations removed: strip of parietal peritoneum retained on right side.
- Cardia, cardiac orifice, and lesser curvature of stomach: the body, fundus and greater curvature of stomach are removed.
- Mucosa and rugae of the stomach.
- Four parts of the duodenum (to duodenojejunal flexure).
- Liver (left lobe mostly removed) and gallbladder.
- Inferior border of the liver elevated to expose the porta hepatis and associated structures, and the hepato-duodenal ligament and its content.
- Position and relations of the pancreas and vessels of the retroperitoneal space.
- Kidneys and superior (proximal) part of the ureter, and their relationship with psoas major and quadratus lumborum.
- Renal hilum with associated arteries and veins.
- Spleen with associated arteries and veins, and its relationship with the left kidney.
- Abdominal aorta at the aortic hiatus of the diaphragm and the origin of the coeliac trunk.
- Branching of the coeliac trunk, including its branches to the inferior part of the oesophagus and the anastomotic loops formed by the gastric and gastroepiploic arteries to the curvatures of the stomach.
- Peritoneal ligaments of the liver, including the falciform and round (teres) ligament.
- Formation and course of the hepatic portal vein.
- Position of the abdominal aorta and inferior vena cava.
- Superior mesenteric artery and vein (proximal parts) and their relationship with the pancreas and duodenum.
- Origin of the inferior mesenteric artery from the abdominal aorta.
- Sympathetic trunk and sympathetic ganglia.
- Latissimus dorsi and thoracolumbar fascia.
- Transverse section through the superior part of the lumbar vertebral column, with associated muscles, spinal cord and its meningeal coverings in the vertebral canal (required removal from stand).
Possible variants or pathology (not guaranteed)
- Branching patterns of vessels, nerves, and nerve plexuses.
- Variant origins of arteries (e.g., a coeliaco-mesenteric trunk, an aortic or superior mesenteric of origin of the coeliac trunk branches, and an aberrant or polar renal artery).
- Vertebral level of origin, position and course of vessels and nerves.
- Tortuosity of arteries.
- Arterial aneurysm and atherosclerosis.
- Osteoarthritis and disease-related joint deformity.
- Rheumatological bone and soft tissue changes.
- Distended thoracic or abdominal cavity.
- Morphology and position of viscera and muscles (e.g., inferiorly elongated right (Reidel) lobe of liver).
- Hepatic or renal segments show differential levels of coloured polymer perfusion (colouration).
- Pathology of the viscera (e.g., hepatic or renal cyst).
- Age-related changes to viscera and soft tissues.
- Enlarged lymph nodes (e.g., intercostal, para-aortic).
Available customisations
- Reveal three layers of intercostal muscle in one intercostal space.
- Retain the parietal pleura on one side of thorax and diaphragm.
- Retain greater curvature of stomach as a strip.
