Intestinal ischemia is an uncommon disorder, whose incidence is nevertheless increasing and whose mortality remains high. The major cause of its poor prognosis is represented by the diagnostic delay depending on the poor specificity and late onset of the various clinical, biohumoral and radiographic signs associated with bowel infarction. On the one hand, the aspecificity of clinico-humoral findings and on the other hand its invasiveness prevent a broad use of angiography and call for the introduction of noninvasive methods. In our experience on 17 cases, Computed Tomography (CT), exhibiting sensitivity and specificity fairly higher than conventional radiology, makes a valid diagnostic tool in the examination of acute abdomen patients in general and in vascular emergencies in particular. With CT, diagnostic accuracy is fairly increased in acute mesenteric insufficiency. CT allows this condition to be detected earlier than conventional radiology and permits the early recognition, in a larger number of cases, of the patients who will benefit most from a surgical or radiologic treatment.
肠缺血是一种罕见的疾病，但其发病率正在上升，死亡率仍然很高。其预后不良的主要原因是诊断延迟，这取决于与肠梗死相关的各种临床、生物体液和影像学征象的特异性差和出现较晚。一方面，临床体液检查结果缺乏特异性，另一方面其侵入性使得血管造影术无法广泛应用，因此需要引入非侵入性方法。根据我们对17例病例的经验，计算机断层扫描（CT）的敏感性和特异性明显高于传统放射学，是检查一般急腹症患者尤其是血管急症患者的有效诊断工具。使用CT，急性肠系膜缺血的诊断准确性有相当大的提高。CT能够比传统放射学更早地检测到这种情况，并能在更多病例中早期识别出最能从手术或放射治疗中获益的患者。
