Stent-graft repair of isolated iliac aneurysms with wide or ectatic necks with use of inverted zenith device legs.

Although there is considerable experience in the management of iliac artery aneurysms (IAAs) accompanying abdominal aortic aneurysms, less is known about endovascular management of isolated IAAs. The distal landing zone can be secured if necessary by extending the graft to the external iliac artery, but the proximal landing zone remains a challenging issue, on which technical success is dependent. The present report describes a novel technique for endovascular management of isolated IAAs with wide proximal necks for which no commercially available grafts with fitting sizes exist: inversion of the iliac leg of a Zenith device.
