Mesenteric ischemia is a severe pathological condition characterized by inadequate blood supply to the small or large bowel. It accounts for 1% of admissions for an acute abdomen and predominantly affects the elderly. Mesenteric ischemia presents acutely in 95% of cases; chronic mesenteric ischemia accounts for 5% of cases and it is often secondary to severe atherosclerotic disease. Acute mesenteric ischemia is a surgical emergency and may be occlusive (arterial or venous) and nonocclusive. Contrast-enhanced multidetector CT is the first-line imaging modality to evaluate a mesenteric ischemia. Multidetector CT findings in mesenteric ischemia can be classified as: vascular (occlusion of the superior mesenteric artery and/or one of its branches, thrombosis of the superior mesenteric vein and/or one of its branches, porto-mesenteric venous gas); intestinal (mural wall thickening or thinning, abnormal mural enhancement, bowel dilation, bowel wall gas); mesenteric (fat stranding, mesenteric fluid). Contrast-enhanced multidetector CT is the gold standard for diagnosis of mesenteric ischemia. An early and accurate assessment of the CT findings is important for a lifesaving surgery.
