title: Current knowledge on EVAR with the ultra-low profile Ovation Abdominal Stent-graft System.
abstract: Endovascular aneurysm repair (EVAR) has revolutionized the treatment of infrarenal abdominal aortic aneurysms (AAAs). The continuous collaboration of surgeons and bioengineers in the improvement of the devices the last two decades, lead to a continuous redesigning and improvement of the various endografts. In the last few years, the majority of companies have developed renewed models of grafts and have modified delivery systems tending to lower profile in order to deal with difficult anatomies. The ultra low profile 14F OD Ovation (Trivascular) Abdominal Stent-graft System with innovative sealing technology achieved through inflatable sealing rings, allows treatment of AAAs with small in diameter access vessels that might be unsuitable for EVAR with other currently available stent-grafts. The aim of the present paper was to analyze the technical characteristics and properties of this endograft and to review the current literature.
