Endovascular aneurysm repair has become the first-line treatment for abdominal aortic aneurysms and iliac artery aneurysms in recent years. However, the diameter of the infrarenal aorta is larger than that of the aortic bifurcation, especially with small aortic diameters, for which a reversed tapered device is necessary. We describe the off-label use of the upside-down Gore Excluder limb and double-barrel sandwich technique for the treatment of a penetrating abdominal aortic ulcer with a large common iliac artery aneurysm. These techniques offer an easy endovascular approach for excluding an aneurysm in selected patients. However, this technique is outside the standard instructions for use, therefore careful planning and long-term follow-up are mandatory.
