Intestinal ischemia, which refers to insufficient blood flow to the bowel, is a potentially catastrophic entity that may require emergent intervention or surgery in the acute setting. Although the clinical signs and symptoms of intestinal ischemia are nonspecific, computed tomography (CT) findings can be highly suggestive in the correct clinical setting. In our article, we review the CT diagnosis of arterial, venous, and nonocclusive intestinal ischemia. We discuss the vascular anatomy, pathophysiology of intestinal ischemia, CT techniques for optimal imaging, key and ancillary radiological findings, and differential diagnosis.
肠缺血是指肠道血流不足,是一种潜在的灾难性疾病,在急性情况下可能需要紧急干预或手术。尽管肠缺血的临床体征和症状不具有特异性,但在正确的临床背景下,计算机断层扫描(CT)结果可能具有高度提示性。在我们的文章中,我们回顾了动脉性、静脉性和非闭塞性肠缺血的CT诊断。我们讨论了血管解剖、肠缺血的病理生理学、优化成像的CT技术、关键和辅助放射学表现以及鉴别诊断。
