A 73-year-old man had a past history of high blood pressure, hypercholesterolemia, and chronic ischemic cardiopathy. He came to our center with symptoms of postprandial abdominal pain in the epigastrium. Abdominal computed angiotomography showed permeability and normal caliber of the superior and inferior mesenteric arteries. Stricture due to median arcuate ligament impression was identified at the level of the emergence of the celiac trunk (Figs. 1 and 2).
The median arcuate ligament is a fibrous arc that joins the diaphragmatic columns on both sides of the aortic hiatus. It is usually located above the celiac trunk, but its situation is anterior to it in 24% of the general population. When this anatomic alteration compromises blood flow it is known as median arcuate ligament syndrome, or Dunbar's syndrome. Treatment is surgical, whether or not it is associated with celiac trunk revascularization, through angioplasty and stent placement. In our case, the patient rejected the surgical option.
