Endovascular repair of bilateral common iliac aneurysms with iliac branch endoprostheses has been reported to be safe and effective. However, anatomic constraints, such as inadequate proximal iliac seal zones and short renal artery to iliac bifurcation lengths, can preclude deployment in certain configurations and limit use in many patients. We present an innovative technique to overcome these anatomic constraints and extend the reach of IBE technology to patients with common iliac artery aneurysms.
