Understand the celiac trunk through its aortic origin, three major branches, foregut blood supply, anatomical relations, and variations.

Card 1 of 30Question

What is the celiac trunk?

A short, unpaired visceral branch of the abdominal aorta that supplies the foregut and its associated organs.

In This Section

1. What is the celiac trunk?

A short, unpaired visceral branch of the abdominal aorta that supplies the foregut and its associated organs.

2. From which vessel does the celiac trunk normally originate?

The abdominal aorta.

3. At approximately which vertebral level does the celiac trunk arise?

The T12 vertebral level, near the aortic hiatus of the diaphragm.

4. From which surface of the abdominal aorta does the celiac trunk arise?

The anterior surface.

5. Which major abdominal artery arises immediately inferior to the celiac trunk?

The superior mesenteric artery.

6. What is the approximate length of the celiac trunk in typical anatomy?

Approximately 1 to 2 cm, although its length varies.

7. What are the three classical branches of the celiac trunk?

The left gastric, splenic, and common hepatic arteries.

8. What is the classical three-branch arrangement of the celiac trunk called?

The tripod of Haller.

9. Which embryological division of the gastrointestinal tract is primarily supplied by the celiac trunk?

The foregut.

10. Which gastrointestinal structures are included in the principal foregut territory of the celiac trunk?

The abdominal esophagus, stomach, and proximal duodenum.

11. Which accessory digestive organs receive their principal arterial supply through branches of the celiac trunk?

The liver, gallbladder, pancreas, and spleen.

12. Which branch of the celiac trunk ascends toward the lesser curvature of the stomach?

The left gastric artery.

13. Which artery typically anastomoses with the left gastric artery along the lesser curvature?

The right gastric artery.

14. Which branch of the celiac trunk travels toward the spleen?

The splenic artery.

15. Along which anatomical border of the pancreas does the splenic artery typically course?

The superior border of the pancreas.

16. Which branch of the celiac trunk generally travels toward the right side of the upper abdomen?

The common hepatic artery.

17. What are the two main terminal branches of the common hepatic artery in classical anatomy?

The proper hepatic and gastroduodenal arteries.

18. Which branch of the common hepatic artery supplies the liver through its right and left hepatic divisions?

The proper hepatic artery.

19. Which artery arising from the hepatic arterial system usually supplies the gallbladder?

The cystic artery, usually arising from the right hepatic artery.

20. Which artery supplies the proximal duodenum through its superior pancreaticoduodenal branches?

The gastroduodenal artery.

21. Which arterial networks connect the celiac trunk territory with the superior mesenteric artery territory?

The anterior and posterior pancreaticoduodenal arterial arcades.

22. Which arterial branches form the pancreaticoduodenal arcades?

The superior pancreaticoduodenal branches of the gastroduodenal artery and inferior pancreaticoduodenal branches of the superior mesenteric artery.

23. What is the relationship of the celiac trunk to the lesser sac?

The celiac trunk lies posterior to the lesser sac.

24. Which autonomic nervous plexus surrounds the origin and proximal branches of the celiac trunk?

The celiac plexus.

25. Which sympathetic ganglia are closely associated with the celiac trunk?

The right and left celiac ganglia.

26. Which diaphragmatic structure may compress the proximal celiac trunk?

The median arcuate ligament.

27. What is median arcuate ligament syndrome?

Symptomatic compression of the celiac artery and sometimes the adjacent celiac plexus by the median arcuate ligament.

28. What is a hepatosplenic trunk variation?

A common trunk for the hepatic and splenic arteries, with the left gastric artery arising separately.

29. What is a celiacomesenteric trunk?

A rare arterial variation in which the celiac and superior mesenteric arterial territories share a common aortic origin.

30. Why is identifying celiac trunk branching variations important before upper abdominal surgery?

Variant arterial anatomy can affect organ perfusion and increase the risk of inadvertent vascular injury.
