Pseudostenosis of the External Iliac Artery after Common Iliac Artery Occlusion: 2 Case Reports

We report 2 cases of pseudostenosis of the external iliac artery (EIA) combined with aortoiliac occlusive disease. Both cases were treated successfully by aortobi-iliac bypass surgery instead of aortobi-femoral bypass. Pseudostenoses of the EIA disappeared in the postoperative computed tomographic angiography. We are not aware of previous reports of similar findings. Pseudostenosis should be considered if the EIA shows diffuse narrowing without wall irregularity in combination with severe stenosis or occlusion of the common iliac artery.
