Mesenteric Duplex

A Mesenteric Duplex Study examines blood flow in the arteries that carry oxygen-rich blood to the stomach, intestines, pancreas, spleen, and organs that reside in the abdomen. A mesenteric artery stenosis (a narrowing or blockage of the mesenteric artery) can contribute to mesenteric ischemia, a potentially very serious condition. During the ultrasound scan the technologist will pass a risk-free, painless non-invasive ultrasound transducer (probe or wand) over your upper abdomen to evaluate the quality and direction of flow in the superior and inferior mesenteric arteries. Other arteries routinely examined include the abdominal aorta, celiac, hepatic and splenic arteries.


  • Abdominal pain when eating
  • Unexplained weight loss or fear of food
  • Diarrhea or abdominal bruit
  • Monitoring of mesenteric, celiac, or splenic arteries

Patient Preparation

Patients should fast for 6-8 hours prior to their exam. However, patients should take current medications as usual with a small sip of water.
