Due to arterial or venous thromboembolism, hypoperfusion or extrinsic vascular compression.
Ischaemia causes mucosal oedema and sloughing, which may repair itself completely or progress to fibrosis and stricture.
CT
• Dilated and thickened bowel—the splenic flexure is a typical location (watershed zone between superior mesenteric artery/inferior mesenteric artery [SMA/IMA]).
• Hypoenhancement of the affected bowel.
• Stranding of the adjacent fat suggests transmural infarction.
• Pneumatosis or portal venous gas indicates transmural necrosis.
• Engorged mesenteric veins and ascites.
• Follow-up for several months to monitor for stricture formation.
