Patient Data

Age: 55 years
Gender: Male

CT Abdomen and pelvis


Severe atheromatous disease along the abdominal aorta with infrarenal segment occlusion by thrombus, which extends to common iliac arteries. Collateral circulation is noted between the SMA and IMA via what seems to represent an Arc of Riolan (although it shows a short segment running close to the left colon that resembles a marginal artery). 

Case Discussion

Leriche syndrome refers to the symptoms related to a complete occlusion of the aorta distal to the renal arteries.
