Iliac conduit for deploying aortic endografts: an all-autogenous option

Unfavorable iliac anatomy, such as small caliber or circumferential calcification, can cause problems during delivery of aortic endografts and lead to potential complications. An iliac artery conduit "chimney" has been used to deliver the large caliber endoprosthesis using a Dacron graft sewn onto the iliac bifurcation. An all-autogenous revascularization option allows for hypogastric bypass while limiting the use of synthetic graft.
