慢性肠道缺血通常是由腹主动脉内脏分支的动脉粥样硬化引起的。它通常表现为严重的餐后腹痛、由于害怕进食而导致的体重减轻以及肠道蠕动改变。主动脉造影是明确的诊断研究，通常可以揭示至少两个主要内脏血管的闭塞性疾病。有症状的患者需要进行血运重建，但只有当主动脉重建会威胁肠道侧支血流时，才应对无症状患者进行血运重建。手术技术和围手术期管理的改进提高了内脏重建手术的安全性和有效性。
Chronic intestinal ischemia is usually caused by atherosclerosis of the visceral branches of the abdominal aorta. It classically presents with severe postprandial abdominal pain, weight loss due to fear of eating, and altered intestinal motility. Aortography is the definitive diagnostic study and usually reveals occlusive disease of at least two major visceral vessels. Revascularization is indicated in symptomatic patients but should be undertaken in asymptomatic patients only when aortic reconstruction is indicated that would threaten intestinal collateral blood flow. Refinements in operative technique and perioperative management have improved the safety and effectiveness of visceral reconstruction procedures.
