It may be difficult to access a route to deliver a stent-graft for abdominal aortic aneurysm in high-risk patients with bilateral iliofemoral occlusive disease. These two patients underwent both endovascular aortic aneurysm repair by a modified iliac access conduit technique and sequential ipsilateral iliofemoral artery bypass using the conduit, which provided excellent results. The iliac access conduit facilitates endovascular aortic aneurysm repair and ipsilateral iliofemoral bypass of high-risk patients with abdominal aortic aneurysm and bilateral iliofemoral occlusive disease.
