Mesenteric ischemia (MI) is caused by compromised blood flow to the arteries supplying the small and large intestine. Acute occlusive mesenteric ischemia (AMI) presents with the abrupt onset of severe abdominal pain, which if not diagnosed and treated immediately can cause bowel necrosis and prove fatal. Chronic occlusive mesenteric ischemia (CMI) is usually a longstanding process characterized by postprandial abdominal pain, progressive food intolerance, and weight loss. If untreated, CMI can lead to progressive disability and failure to thrive. This review article highlights the clinical and radiologic diagnosis of acute mesenteric ischemia and CMI and compares their treatment with surgical revascularization and the less invasive alternative of mesenteric artery angioplasty and stenting.
肠系膜缺血（MI）是由供应小肠和大肠的动脉血流受损引起的。急性闭塞性肠系膜缺血（AMI）表现为突然发作的严重腹痛，如果不立即诊断和治疗，可导致肠坏死并危及生命。慢性闭塞性肠系膜缺血（CMI）通常是一个长期过程，其特征为餐后腹痛、进行性食物不耐受和体重减轻。如果不治疗，CMI可导致进行性残疾和发育不良。这篇综述文章重点介绍了急性肠系膜缺血和CMI的临床及放射学诊断，并比较了它们与手术血管重建以及侵入性较小的肠系膜动脉血管成形术和支架置入术的治疗方法。
