There are three main divisions of the celiac artery, and each in turn has its own named branches.

It arises from the celiac artery and has the following branches:

It branches from the celiac artery, and follows a course superior to the pancreas.

The celiac artery may also give rise to the inferior phrenic arteries.

It is also called celiac artery compression syndrome.

Celiac artery compression was first observed by Benjamin Lipshutz in 1917.

Several theories attempt to explain the origin of pain caused by compression of the celiac artery.

Further evaluation and confirmation can be obtained via angiography to investigate the anatomy of the celiac artery.

PTA alone, without deompression of the celiac artery, may not be of benefit.

The median arcuate ligament usually comes into contact with the aorta above the branch point of the celiac artery.

One proposes that compression of the celiac artery causes ischemia, or decreased blood flow, to abdominal organs, leading to pain.

The investigators reported that among patients who underwent celiac artery decompression and revascularization, 75% remained asymptomatic at follow-up.

Complications of MALS result from chronic compression of the celiac artery.

Decompression of the celiac artery is the general approach to treatment of MALS.

Thus it cannot be safely ligated in a living person, and obstruction of the celiac artery will lead to necrosis of the structures it supplies.

Celiac artery (truncus coeliacus)

The mainstay of treatment involves an open surgical approach to divide, or separate, the median arcuate ligament to relieve the compression of the celiac artery.

They give rise to the celiac artery, superior mesenteric artery, and inferior mesenteric artery.

In human anatomy, the left gastric artery arises from the celiac artery and runs along the superior portion of the lesser curvature of the stomach.

A reasonable screening test for patients with suspected MALS is duplex ultrasonography to measure blood flow through the celiac artery.

Peak systolic velocities greater than 200 cm/s are suggestive of celiac artery stenosis associated with MALS.

If blood flow is poor, celiac artery revascularization is usually attempted; methods of revascularization include aortoceliac bypass, patch angioplasty, and others.

The celiac artery supplies oxygenated blood to the liver, stomach, abdominal esophagus, spleen and the superior half of both the duodenum and the pancreas.

The celiac artery is an essential source of blood, since the interconnections with the other major arteries of the gut are not sufficient to sustain adequate perfusion.

Lymph from these organs is drained to the prevertebral celiac nodes at the origin of the celiac artery from the aorta.
