Aortic Occlusion

Abdominal aortogram in the frontal projection. There is occlusion of the distal aorta, just above the level of the bifurcation.

The above image is from later in the same angiographic run. Notice the numerous body wall collaterals from lumbar branches. Just below the level of the occlusion, the aortic bifurcation fills from the collaterals, filling the common iliac arteries (CIAs). Also notice the hypertrophied inferior mesenteric artery (IMA) filling large superior rectal arteries.

Still later in the same run, there is further filling of the common and external iliac arteries
