Aim: We report our preliminary experience with the use of the TriVascular Ovation endograft system for the treatment of abdominal aortic aneurysms (AAA).
Methods: Data from patients treated for AAA using the Ovation endograft at two centers from January 2011 to September 2012 were retrospectively collected and reviewed. Main outcomes included primary success, survival, complications, and device-related events at 30-days.
Results: Thirty-seven patients (male: 95%, mean age: 76 yr) were treated for AAA (mean diameter: 54 mm) with the Ovation endograft, mainly using local or regional anesthesia (86.5% of cases). Percutaneous femoral access was utilized in 73% of cases. Primary success was achieved in 89.2% of cases, as 4 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, major complications, endoleaks, AAA enlargement, AAA rupture, stent fracture, migration, or endovascular or surgical reintervention were reported at 30-days.
Conclusion: Our initial experience with the Ovation endograft demonstrated encouraging 30-day results for the treatment of AAA.
