- Shock bowel is reversible small bowel ischemia related to hypovolemia.
- Hypoperfusion results in increased bowel permeability to macromolecules and albumin which leads to
- Diffuse bowel wall thickening
- Increased enhancement on CT scans due to slowed perfusion and interstitial leakage of molecules of contrast material
- Accumulation of intraluminal fluid secondary to the failed resorption capacity.
- Shock bowel resolves with resolution of hypovolemia; this fact suggests that this finding represents a reversible ischemic change without clinical significance.
 Imaging Findings
- Mild to moderate diffuse small-bowel thickening and marked hyperenhancement of the mucosa.
