What does the IMA feed?

The IMA supplies blood to the distal one-third of the transverse colon, descending colon and proximal two-thirds of the rectum.

What does the superior mesenteric artery feed?

The superior mesenteric artery provides oxygenated blood and nutrients to the intestines. These organs are part of the digestive system. The artery branches off of the aorta, which is the body’s largest blood vessel. Superior refers to the artery’s location above other arteries that supply the intestines.

What supplies inferior mesenteric artery?

Inferior mesenteric artery

Origin Abdominal aorta at level of L3
Branches Left colic, Sigmoid, Superior rectal arteries Contributes to the formation of the marginal artery of Drummond Mnemonic: Lesley Sings Songs
Supplies Left third of transverse colon, descending colon, sigmoid colon, rectum

What does the middle colic artery supply?

The middle colic artery is a branch of the superior mesenteric artery that supplies the proximal two-thirds of the transverse colon. It courses intraperitoneally through the root of the transverse mesocolon until it splits into right and left branches.

What level is the IMA?


In human anatomy, the inferior mesenteric artery, often abbreviated as IMA, is the third main branch of the abdominal aorta and arises at the level of L3, supplying the large intestine from the distal transverse colon to the upper part of the anal canal.

What artery feeds the small intestine?

The blood supply to the small and large bowel is derived from the celiac artery and SMA. The celiac axis primarily provides blood flow to the stomach, liver, spleen, and pancreas but is also a source of collateral flow when blood flow in the SMA is reduced.

What happens if inferior mesenteric artery is blocked?

In mesenteric ischemia, a blockage in an artery cuts off blood flow to a portion of the intestine. Mesenteric ischemia (mez-un-TER-ik is-KEE-me-uh) occurs when narrowed or blocked arteries restrict blood flow to your small intestine. Decreased blood flow can permanently damage the small intestine.

What is IMA artery?

The inferior mesenteric artery (IMA) is one of the three non-paired major splanchnic arteries, in the abdominal cavity, arising from the abdominal aorta and supplying the hindgut. It is the smallest of the three anterior visceral branches of the abdominal aorta.

Where does the inferior mesenteric vein drain into?

splenic vein

The inferior mesenteric vein, a continuation of the superior rectal vein, accompanies the inferior mesenteric artery and usually drains into the splenic vein.

What vertebral level is celiac trunk?

The celiac trunk originates in the ventral aspect of the aorta, just after it crosses the diaphragmatic aortic hiatus, at the level of the 12th thoracic and first lumbar vertebrae and trifurcates into the common hepatic artery, left gastric artery and splenic artery [1].

What artery supplies the kidney?

renal arteries

The renal arteries are large blood vessels that carry blood from your heart to your kidneys. Renal is another word for kidney. You have two renal arteries. The right renal artery supplies blood to the right kidney, while the left artery sends blood to the left kidney.

What are the three main branches off of the celiac trunk artery )?

The celiac trunk gives off branches to the diaphragm, then divides into three main branches, the small left gastric artery which goes straight up, and the large common hepatic, and splenic arteries, which go to the right and left.

Can you stent the celiac artery?

Celiac arterial stenting, as shown in our two patients, could be easily and safely employed in patients with PDA aneurysm associated with a stenotic celiac arterial root to release the stenosis of the celiac arterial root and to prevent further possible bleeding.

What part of the body is the celiac?

The celiac trunk, also known as the celiac artery, is a short vessel that arises from the aorta and passes below the median arcuate ligament, just as the aorta enters the abdomen at the level of the T12 vertebra. The celiac trunk measures about 1.5cm to 2cm in length.

What causes celiac artery blockage?

Celiac trunk stenosis is a relatively common finding; the most common causes of this obstruction are median arcuate ligament syndrome, pancreatitis, local invasion of various malignancies originating from the pancreatic body, atherosclerosis or it can be idiopathic.

What happens if MALS goes untreated?

MALS complications include long-term pain, especially after meals, which can lead to a fear of eating and significant weight loss. The pain and related depression or anxiety can greatly impact your quality of life.

Who treats celiac stenosis?

Patients with celiac artery stenosis/occlusion are treated by interventional radiology (IR) via dilation of the pancreaticoduodenal arcade. In patients with dilation of the pancreaticoduodenal arcade on SMA angiograms, IR through this artery may be successful.

What are the symptoms of a blocked celiac artery?

What Are the Symptoms of Celiac Artery Compression Syndrome? The main symptoms are chronic abdominal pain that has lasted several months, abdominal pain after eating, weight loss, and sometimes an abdominal bruit, or the sound made by blood flowing through an obstruction.

What organs does the celiac artery supply?

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

Can MALS go away?

Surgery is the only treatment option for MALS . The most common procedure is called median arcuate ligament release, or median arcuate ligament decompression. It’s usually done as an open surgery but sometimes can be done as a minimally invasive (laparoscopic or robotic) procedure.
