An update on the ovation abdominal stent graft for the treatment of abdominal aortic aneurysms: current evidence and future perspectives

ABSTRACT

Introduction: The Ovation stent-graft has presented satisfactory mid-term results in the management of abdominal aortic aneurysms (AAA). Its unique design with uncoupling of fixation and sealing and the lowest profile in the market has expanded the treatment in AAA with challenging neck anatomies and, especially, in the females presenting mostly with narrow iliac access vessels. Morever, a new design modification, the Ovation Alto was recently introduced in the Market, while certain off-label uses of the Ovation in treating either juxtarenal- or short-necked AAA have been proposed.

Areas covered: Aim of this article was to present the current articles with the long-term results of the Ovation endograft and discuss the new developments and modifications in its use.

Expert commentary: the Ovation stent-graft exhibits very satisfactory clinical long-term results in AAA treated within the instructions-for-use, expands significantly the treatment of AAA in females and overcomes reliably challenging anatomical issues of the infrarenal neck that would render these cases ineligible for treatment with any other endograft. Εxperience with the specific, unique technical features of Ovation as well as careful selection of patients and meticulous preoperative study of the AAA anatomy are key-elements to the successful performance of this endograft.

Article highlights

• The ovation stent-graft confirms in newer studies a satisfactory technical success in cases with challenging infrarenal neck anatomy.

• Newer studies and database analyses demonstrate favorable long-term results in terms of reintervention-free intervals and clinical success.

• This low-profile device has favorable results for the smaller AAA anatomies of the females and treats cases previously ineligible for EVAR with any other aortic stent-graft.

• The Ovation Alto design nearly eliminates the PTFE narrow band between the suprarenal stent and the polymer inflatable rings and promises efficient sealing in AAA with a very short neck.

• The vent technique is safe and feasible and increases the range of treatment of those patients with juxtarenal AAA who are unfit for open repair or fenestrated EVAR because of anatomic constraints.
