Superior Mesenteric Artery Stenosis Ultrasound Criteria. It has been shown that native vessel criteria overestimate the degree of in-stent restenosis ISR and that velocity criteria for SMA and CA ISR are not well established. There was ultrasound evidence of a proximal superior mesenteric artery SMA stenosis of 70 based on the published criteria. This two-vessel rule holds in most patients and is utilized clinically for the diagnosis of chronic mesenteric ischemia. The gastrointestinal tract is supplied by the celiac trunk the superior mesenteric artery SMA and the inferior mesenteric artery IMA The celiac trunk originates from the anterior aorta just below the diaphragm at the level of the thoracic.
