A modular multi-branched system for endovascular repair of bilateral common iliac artery aneurysms

Purpose: To describe a modular stent-graft for cases of bilateral common iliac aneurysm. Technique: The aortic aneurysm is repaired using a standard bifurcated modular system (Zenith). A modified bifurcated component is deployed with its trunk in one limb of the original aortic stent-graft, its long limb in the external iliac artery, and its short limb in the iliac aneurysm just above the internal iliac orifice. A flexible extension is introduced from the right brachial artery and used to bridge the gap between the short limb of the modified bifurcated component and the left internal iliac artery. Conclusions: Endovascular repair of bilateral iliac aneurysm is feasible using a modular stent-graft with separate branches to the internal and external iliac arteries.
