BACKGROUND: Aim of the study was to evaluate the initial results of endovascular aneurysm repair with the Ovation abdominal stent-graft system in patients with challenging aortoiliac anatomy.
METHODS: The Ovation stent-graft is an ultra-low profile, modular endovascular graft characterized by a 14F OD delivery system, active suprarenal fixation, and polymer-filled proximal rings that allow sealing in short (≥7 mm) proximal necks. Between November 2010 and January 2012, 14 patients with abdominal aortic aneurysms (AAA) (male: 100%, mean age: 76 years, mean AAA diameter: 54 mm) and challenging aortoiliac anatomy were treated with the Ovation endograft at a single centre. Mean patient follow-up was 5 months.
RESULTS: All cases were performed under local or epidural anesthesia. No operative deaths or major complications were noted. A type I endoleak was detected on final angiogram in one case, which was successfully treated with additional ballooning and Palmaz stenting of the hooking landing zone. One patient died at 2 months due to myocardial infarction unrelated to the device or procedure. AAA-related mortality was 0%. No AAA rupture, AAA enlargement, type I or III endoleak, stent migration, access site complication, or conversion to open surgery was reported during follow-up. A type II endoleak was successfully treated with a right lumbar artery embolization at 4 months. Occlusion of an iliac axis was successfully managed with local fibrinolysis and implantation of a covered stent in the external iliac artery.
CONCLUSIONS: Initial outcomes of this single-center experience suggest that the Ovation abdominal stent-graft system is a promising treatment in AAA patients with challenging aortoiliac anatomy.
