Enhanced CT showed non-enhancing thrombotic obstruction of the left common iliac artery iliac artery (arrow) and accompanied large retroperitoneal hematoma (arrowheads). These findings suggested the possibility of iatrogenic arterial laceration with dissecting arterial occlusion and periarterial hematoma formation.

Contrast-enhanced CT also revealed a low attenuation perfusion defect in the common iliac artery at the level of L4-5 with a moderate amount of retroperitoneal hematoma (Fig. 1).
Pelvic angiography showed short segmental abrupt arterial obstruction in the left common iliac artery (arrows), suggestive of arterial dissection with occlusion. There is reconstitution of the left internal and external iliac arteries (arrowheads) through pelvic collateral pathways.

Angiography of the abdomen demonstrated a complete obstruction of the left common iliac artery, located about 2 cm distal to the aortic bifurcation (Fig. 2).
