The upside down Gore Excluder contralateral leg without extracorporeal predeployment for aortic or iliac aneurysm exclusion.

Endovascular techniques, including branched devices to preserve the internal iliac artery are evolving rapidly, but in cases in which the diameter of the proximal sealing zone is larger than that of the distal sealing zone, a reversed tapered device is needed. We describe the off label use of the Gore Excluder contralateral leg endoprosthesis in an upside down configuration to accommodate this diameter mismatch. The preinsertion technical steps of stent graft preparation, which do not require extracorporeal predeployment, are described in detail. As such, an aneurysm of the internal iliac artery and a saccular abdominal aortic aneurysm were successfully excluded.
