Celiac Axis Anatomy

In our study normal celiac axis anatomy was seen in 91 figure 1. The median arcuate ligament is the fibrous arch that unites the diaphragmatic crura forming the anterior arc of the aortic hiatus.

The celiac axis arises from the ventral surface of the aorta at the t12 l1 vertebral body.

Celiac axis anatomy. Celiac artery also known as the celiac axis or celiac trunk is a major visceral artery in the abdominal cavity supplying the foregut. The most common anatomic variation was of hepatosplenic trunk with separately originating left gastric artery lga and sma 283 figure 2. In this article we shall look at the anatomy of the coeliac trunk its anatomical position branches anastomoses and clinical relevance.

There are many potential anatomic configurations with up to half the population having a variation from the classic pattern of the ca bifurcating into the hepatosplenic trunk and left gastric artery. The celiac artery is the only major artery that nourishes the abdominal digestive organs that does not have a similarly named vein. Anatomy explorer abdominal aorta.

Anatomical position the coeliac trunk is the second branch of the abdominal aorta the first branches are the paired inferior phrenic arteries. In 48 of the celiac angiograms the celiac axis arose from the aorta high at the pedicle of the t 12 vertebral body contrary to the common belief that the celiac axis arises near the t12 l1 interspace. A total of 4457 891 of the 5002 patients had a normal celiac axis anatomy which appeared as a hepatogastrosplenic trunk and sma originating separately from the aorta.

Of the 15 celiac axis anatomy types 13 were identified in our study figs e1ae1m online. It courses anteroinferiorly before branching into the common hepatic splenic and left gastric arteries. The celiac trunk is a critical blood source for the gut since the other major arteries arent connected in such a way that continue scrolling to read more below.

It arises from the abdominal aorta and commonly gives rise to three branches. The superior mesenteric artery arose at the level of l 1 in 83 of the 24 angiograms and below the pedicle of l 1 in 5 21. Left gastric artery splenic artery and common hepatic artery.

According to michels the prevalence of a normal celiac axis anatomy is 89. The celiac trunk is a major branch of the abdominal aorta originating anteriorly near the level of the diaphragm and usually in close proximity to the median arcuate ligament. The celiac axis ca and its branches are critically important arteries that supply blood to the vital solid and hollow abdominal viscera of the foregut.

Most blood returning from the digestive organs including from the area of distribution of the celiac artery is diverted to the liver via the portal venous system for further processing and detoxification in the liver before returning to the systemic circulation via the hepatic veins.
