Overview

Computerised axial tomographic angiography should be performed as soon as possible in order to diagnose mesenteric ischemia becasue of its ability to define the arterial anatomy and demonstrate the site of occlusion.

CT

  • Computerised axial tomographic angiography with intravenous contrast is the diagnostic test of choice for mesenteric ischemia regardless of the etiology.[1][2]
  • Following radiological features are seen more prominently on CT imaging of mesenteric ischemia.[3]

Yellow arrow shows multiple small bowel loops and proximal large bowel show wall edema or thickening and hypo-enhancement, Mild mesenteric congestion, No free fluid or uncontained gas, Central filling defect is seen at the superior mesenteric artery post middle colic artery branch : Radiopedia.org - Case contributed by Dr. Abdallah Khateeb

Patient #1: CT images of patient with ischemic bowel demonstrates pneumatosis and portal venous gas

Patient #2: CT images demonstrate mesenteric ischemia with marked atherosclerosis of arteries
