However, the aorta appeared to end abruptly at the point where the right common iliac would be expected to originate (Figure 1A, Figure 1B, Figure 1C, Figure 1D). Multiple lumbar and retroperitoneal collaterals reconstituted the right internal iliac artery (Figure 1B, Figure 1C, Figure 1D).
The left internal (green arrow) and external (red arrow) iliac arteries are also seen. Retroperitoneal collaterals (yellow arrow) reconstitute the right internal iliac artery.

The distal portion and the right common femoral artery were reconstituted from the right inferior epigastric artery, deep circumflex iliac artery and the contralateral common femoral artery (Figure 2A, Figure 2B, Figure 2C).
