A Rare Complication of Iliac Limb Occlusion After Endovascular Aortic Aneurysm Repair Using the Zenith Inverted Limb

抄録

This is a report on the case of a rare complication of an iliac occlusion that occurred after endovascular aortic aneurysm repair (EVAR) with a Zenith inverted limb. This case involved the treatment of a common iliac artery aneurysm. Owing to the short distance from the patient' s lowest renal artery to the aortic bifurcation, we planned the EVAR using a Zenith Inverted limb, which has a contralateral limb inverted into the main body. The EVAR was successfully performed. However, an occlusion occurred in the ipsilateral leg because of the fully opened contralateral leg that hampered the blood flow into the ipsilateral side. Therefore, we extended the ipsilateral leg proximally to the same level as the contralateral leg. To the best of our knowledge, no other cases involving occlusion of the Zenith inverted limb have been reported. Based on our experience, we recommend that attention should be focused on the position of the ipsilateral leg to prevent limb occlusion when deploying a Zenith inverted limb.
