Objective: We describe our initial experience with the use of the TriVascular Ovation endograft system for the treatment of abdominal aortic aneurysms (AAA).
Methods: We retrospectively reviewed data from patients treated for AAA using the Ovation endograft at two institutions from January 2011 to September 2012. Main outcomes included primary success, survival, complications, and device-related events. The mean follow-up period was 10 months (range 1-22 months).
Results: Thirty-seven patients (male: 95%, mean age: 76 yr) were treated for AAA (mean diameter: 54 mm) with the Ovation endograft. Local or regional anesthesia was used in 86.5% of cases. Percutaneous access was utilized in 73% of cases. Primary success was 89.2% (33/37). Four adjunctive procedures were required including two distal extensions (type 1b endoleak and iliac limb disconnection resulting in type III endoleak) and two bypass surgeries (limb graft occlusion and gate cannulation failure). No deaths or major complications were reported during the procedure or in follow-up. No type I, III, or IV endoleak, AAA enlargement, AAA rupture, stent fracture, migration, or endovascular or surgical reintervention were reported during the follow-up period. Type II endoleak was observed in two patients. Asymptomatic narrowing of both iliac limbs was observed in one patient at 6 months.
Conclusions: Our initial experience with the Ovation endograft demonstrated encouraging results in patients with AAA.

Low profile endografts for the endovascular treatment of abdominal aortic aneurysms.

Article Synopsis
- A systematic review of low-profile endografts (LPE) used in endovascular aneurysm repair (EVAR) for abdominal aortic aneurysms (AAA) was conducted to compare long-term outcomes and complications.
- The review analyzed 36 studies involving over 5,000 patients and found similar survival rates and reintervention rates among the three types of endografts (Incraft, Zenith LP/Alpha, and Ovation) at one and three-year follow-ups.
- Notably, the Zenith device had a higher incidence of limb stenosis/kinking, while the Incraft device showed a lower occurrence of type III endoleaks.
Endografts for the treatment of abdominal aortic aneurysms with a hostile neck anatomy: A systematic review.

Department of Vascular Surgery, University of Patras Medical School, Patras, Greece.
Background: Endovascular aortic repair (EVAR) of abdominal aortic aneurysms (AAAs) has emerged as a better alternative to conventional open surgery for AAAs. The purpose of the review is to define the improvement in the clinical management of the patient with hostile neck AAAs due to the introduction of new endografts while giving a thorough description of their instructions for use (IFUs), main characteristics and part sizing, reporting their outcomes from clinical studies and categorizing their usability.
Methods: A MEDLINE search was conducted using keyword-specific combinations.

Background: Patients with wide aortic necks undergoing Endovascular Aneurysm Repair (EVAR) have been shown to be at a higher risk for neck-related complications. We aim to examine outcomes of EVAR with an endograft exerting minimal outward pressure (Ovation-Endologix) in patients with a large baseline neck diameter.
Methods: We performed a retrospective single center study, including consecutive patients undergoing EVAR with the Ovation system from May 2011 to April 2021.
Endovascular Abdominal Aortic Aneurysm Repair With Ovation Alto Stent Graft: Protocol for the ALTAIR (ALTo endogrAft Italian Registry) Study.

Article Synopsis
- The Ovation Abdominal Stent Graft System, including its redesigned version called Ovation Alto, provides a new sealing option for repairing abdominal aortic aneurysms (AAA), with CE Mark approval granted in August 2020 for the Alto model.
- This registry study aims to assess the outcomes of patients undergoing elective endovascular aneurysm repair (EVAR) using the Alto stent graft, with an estimated 300 participants across various centers over a 24-month enrollment period followed by a 5-year follow-up.
- Key goals include evaluating the technical and clinical success of the procedure as well as analyzing factors such as operative time, radiation exposure, and the impact of patient characteristics and device configuration on outcomes.
"Aortic Balloon Molding" during Ovation Endograft Implantation Expands Graft Use for Hostile Neck Anatomy.

Background: Challenging aortoiliac anatomy such as short neck and narrow access vessels is responsible for endovascular repair of abdominal aortic aneurysm (EVAR) ineligibility in up to 50% of cases. The Ovation stent graft helped widen the range of abdominal aortic aneurysms (AAAs) suitable for EVAR thanks to its low-profile delivery system and polymer-filled sealing rings. However, its advantages are offset by a tight sizing chart that can lead to increased risk of type Ia endoleak or endograft infolding from under- or oversizing, respectively.
