Abstract
A 64 year old woman presented with acute on chronic mesenteric ischaemia (CMI). Computed tomography angiogram (CTA) showed occlusion of the coeliac and superior mesenteric arteries (SMA). (A) A highly developed inferior mesenteric artery (IMA) supplied the SMA via the marginal artery of Drummond (white arrow) and intermesenteric connections (red arrows). SMA stenting allowed for a straightforward clinical improvement. (B) Follow up CTA at six months showed significant IMA and intermesenteric connection regression, leaving a high flow induced aneurysm (arrow). Restoring anterograde SMA blood flow is paramount in CMI, despite the optimal development of the mesenteric collateral network.Image 1
