CTICasesChronic Aortic Dissection with Bowel Ischemia Post-Stenting

Imaging findings
CT angiogram reveals a chronic aortic dissection with a severely compressed true lumen supplying the celiac, superior mesenteric, and renal arteries. Post-stenting CT demonstrates improved flow within the true lumen but new, severe diffuse small bowel distension, bowel wall thickening, loss of haustra in the sigmoid colon, diffuse pneumatosis intestinalis, and mesenteric venous gas, indicating extensive bowel infarction.
Key takeaways
Bowel ischemia is a highly lethal complication of aortic dissection and its intervention. Despite technical success in expanding the true lumen and restoring mesenteric arterial flow on post-stenting imaging, irreversible bowel necrosis may have already occurred or can develop, underscored by findings of pneumatosis intestinalis and portal/mesenteric venous gas.
