Methods and Materials
CT exams of 48 patients with surgical (38) and angiographic (10) definitive diagnosis of intestinal infarction were retrospectively evaluated.
In 28 patients the mesenteric ischemia had been caused by the obstruction of an artery,
in 10 by the obstruction of a venous vessel.
In the remaining 10 patients there was no obstruction and a diagnosis of non-occlusive intestinal infarction was made.
All exams were performed in the arterial and venous phases after contrast media injection.
A slice thickeness of 2.5 mm and a reconstruction interval of 1.25 mm were selected in all cases,
using the same 64 slices - CT scanner from June to November 2012.
The frequency of visualization of direct (thrombus) and indirect (wall thickening or thinning,
lack of contrast enhancement of the wall of a loop,
pneumatosis,
mesenteric oedema,
peritoneal fluid) was evaluated on axial images,
multiplanar reformations and maximum intensity projection reconstructions of the mesenteric circle.
