Celiac and Mesenteric Angiogram

Celiac and mesenteric angiography are procedures in which the celiac and mesenteric arteries are studied via fluoroscopy (live x-ray). Both the celia and mesenteric arteries are located in the belly, and are the major branches of the abdomial aorta.

The celiac (or coeliac) artery is the first major branch of the abdominal artery and supplies oxegenated blood to the stomach, liver, spleen, the abdominal esophagus, and parts of the duodenum and pancreas. The superior mesenteric artery (SMA) and the inferior mesenteric artery (IMA) form the other two branches of the abdominal artery, and supply the colon, the ileum, cecum, appendix, jejunum, and parts of the duodenum.

A celiac or mesenteric angiogram can detect or rule out aneurysm, thrombosis, ischemia, and can be used to locate the source of gastrointestinal bleeding. It can also aid in the diagnosis of portal hypertension and cirrhosis.

If either the celiac or  SMA artery is found to be restricted or narrowed, a stent can be placed to hold the vessel open and allow blood to flow freely.

Celiac and mesenteric angiography are catheter-based procedures that our doctors perform in our freestanding facility. The procedures can take up to three hours, depending on the number of vessels explored. No overnight stay is required.

Celiac and SMA stent placement are catheter-based procedures that our doctors perform in our freestanding facility. The procedure takes about an hour and no overnight stay is required.

 

 

Stenting

A stent is a tiny mesh tube that is inserted into a vessel to reshape the vessel walls. They are often inserted into blood vessels that have been narrowed by plaque buildup (atherosclerosis) or due to collapse. Angioplasty is often performed to widen the blood vessel, then a stent is placed inside the blood vessel to prevent the blood vessel from collapsing or narrowing again. Stents are also placed as stent grafts to create new vessel walls in the case of abdominal aortic aneurysm (AAA).

Stent placement is a catheter-based procedure. The catheter carries the stent to the location of the narrowed or collapsed blood vessel, then the stent is placed in position, possibly as part of the balloon angioplasty procedure.
