Distended mesenteric blood vessel above the costochondral junction
Large colon torsion
Marked thickening of the wall of the large colon is consistent with a diagnosis of
large colon torsion. A colonic wall thickness > 9 mm is an accurate predictor of a
large colon torsion in horses with surgical colic localized to the large colon
(sensitivity – 67%) and correctly determined that large colon torsion was absent with
a specificity of 100%. The detection of nonsacculated large colon in the left ventral
abdomen in horses with abdominal pain is indicative of large colon volvulus. The rate
of decrease in the bowel wall thickness post-surgical correction of a large colon
volvulus correlates with outcome.
