SS 9.2 - Non-occlusive mesenteric ischemia: CT features of reperfusion and their prognostic value
Abstract
Purpose
Non-occlusive mesenteric ischemia (NOMI) is a often a misdiagnosed and a dangerous condition. To our knowledge, an objective evaluation of CT parameters that could correlate with the outcome of patient suffering from NOMI is still missing. The study's aim was to investigate quantitative CT features of reperfusion in NOMI and their prognostic value.
Material and methods
Contrast-enhanced CT examination of 71 patients with a confirmed diagnosis of NOMI (37 with highly suggestive clinical and laboratory features and 34 biopsy proven) were retrospectively reviewed analyzing vessels, mesentery, bowel and peritoneal cavity CT features. Diameter of superior mesenteric artery (SMA), celiac trunk (CeT), inferior vena cava (IVC), superior mesenteric vein (SMV) and differences in CT Hounsfield units (Delta HU) of the bowel wall before and after intravenous contrast media (ICM) administration were correlated to the outcome using Mann-Whitney test. Receiver operating characteristic (ROC) curves were elaborated and combined using predicted probability.
Results
A significant correlation between diameters of SMA, CeT, IVC and SMV and outcome were found (Mann-Whitney p=0.015, p=0.13, p=0.01, and p=0.02 respecrively). Delta HU after ICM administration results also correlated (p=0,005). Area under the curve (AUC) of single variables results were as follows: CeT= 0.672; SMA= 0.667; SMV= 0.717; IVC= 0.728; Delta HU= 0.692. The combined AUC was 0.825.
Conclusion
SMA, IVC, SMV, CeT diameters and Delta HU results correlated with patients suffering from NOMI. A combination of those values allows an accurate prediction of NOMI.
