Endovascular repair of the coverage from the common iliac artery to the external iliac artery after the internal iliac artery embolization has been proven to be a safe and effective treatment in isolated iliac artery aneurysms. But in cases in which the diameter of the proximal sealing zone is larger than that of the distal sealing zone, a reverse-tapered device is needed. We described the off-label use of the Endurant iliac limb stent graft in an upside down configuration to accommodate this diameter mismatch.
