What is the celiac trunk?
Along with the superior and inferior mesenteric arteries, it is one of three frontal branches of the abdominal aorta, the largest artery in the abdominal cavity. Although the celiac trunk is only one of three arteries that branches off the abdominal aorta, it is essential to many major organs.

Variant anatomy. Variations are present in approximately 30%. In general, any of the three celiac branches may arise independently from the aorta or SMA, or the celiac artery may give rise to other branches. A coeliacomesenteric trunk occurs when both the SMA and the celiac trunk originate as a single trunk from the aorta.

It is located at the level of L2-L4 (most often at the L3-L4 disk space level, 2–3 cm above the aortic bifurcation). The IMA supplies the distal transverse colon, descending colon, sigmoid colon, and rectum.

Where is the celiac axis to pancreas?
The celiac axis (or trunk) is the artery, a branch of the aorta, in the upper abdomen that supplies blood to the stomach, pancreas, liver and spleen. In other words, I had stage IV pancreatic cancer, metastasized to the liver and wrapped around the artery.
At which level does the SMA typically originate?
The SMA arises from the anterior surface of the aorta at the level of the first lumbar vertebral body and passes posterior to the neck of the pancreas and SV and follows a course medial and anterior to the uncinate process of the pancreas and the third part of the duodenum.
At what vertebral level does the abdominal aorta bifurcate?
fourth lumbar vertebraThe abdominal aorta is a retroperitoneal structure that begins at the hiatus of the diaphragm and extends to its bifurcation into the right and left common iliac arteries at the level of the fourth lumbar vertebra.
What is the superior mesenteric artery?
The superior mesenteric artery supplies the midgut from the ampullary region of the second part of the duodenum to the splenic flexure of the large intestine. The inferior pancreaticoduodenal artery arises from the SMA and, along with the superior pancreaticoduodenal artery, supplies the head of the pancreas.
Where does superior mesenteric artery branch from?
Inferior pancreaticoduodenal artery- This is the first branch of the superior mesenteric artery, arising from its right side, and supplies the head of the pancreas as well as the inferior and ascending regions of the duodenum.
What is the celiac trunk?
Medically reviewed by the Healthline Medical Network — Written by the Healthline Editorial Team on January 20, 2018. The first major branch of the abdominal aorta, the celiac trunk is responsible for supplying oxygen-rich blood to the stomach, spleen, liver, esophagus, and also parts of the pancreas and duodenum.
What are the three main divisions of the celiac trunk?
There are three main divisions of the celiac trunk: the left gastric artery, the common hepatic artery, and the splenic artery. The left gastric artery runs along the smaller curve of the stomach and connects to the lower esophagus, while the common hepatic artery supplies blood to the liver, duodenum, pancreas, and part of the stomach.

Where does the splenic artery originate?
The splenic artery arises from the coeliac trunk just inferior to the left gastric artery. It then travels left towards the spleen, running posterior to the stomach and along the superior margin of the pancreas. During its course, it is contained within the splenorenal ligament. It terminates into five branches which supply the segments of the spleen.

In addition to supplying the spleen, the splenic artery also gives rise to several important vessels:
Where is the median arcuate ligament located?
The median arcuate ligament (the fibrous anchor of the diaphragm that forms the aortic hiatus) occasionally lies anterior to the coeliac trunk , rather than its usual superior position.

Classic branching of the celiac artery into the left gastric artery, splenic artery , and the common hepatic artery is seen in approximately 70%. Variations are present in approximately 30%. In general, any of the three celiac branches may arise independently from the aorta or SMA, or the celiac artery may give rise to other branches. A celiacomesenteric trunk occurs when both the SMA and the celiac trunk originate as a single trunk from the aorta.
