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.
