A Case of Difficult Catheterization of the Contralateral Limb of the Ovation Abdominal Stent Graft System in Challenging Aortoiliac Anatomy, Facilitated through the Brachial Access: A Word of Caution

The Ovation Stent Graft System is a new trimodular endoprosthesis for the treatment of abdominal aortic aneurysms. A long nitinol stent with anchors serves the suprarenal fixation, whereas inflatable rings in the main body achieve sealing. This dissociation precludes the presence of a nitinol skeleton in the endograft, thus, avoiding competing for the same space within the delivery system, enabling the latter to achieve ultra-low profiles. However, the lack of nitinol support may render the endograft's docking limb prone to collapse in cases of narrow aortoiliac anatomy. We present a case of challenging contralateral limb catheterization, facilitated effectively through the brachial access. Preparing for the brachial route remains a useful and time-sparing adjunctive measure that guarantees the device's safety and effectiveness in challenging anatomies.
