PURPOSE: This study evaluated 2  years of follow-up of the Ovation Abdominal Stent Graft System (TriVascular Inc., Santa Rosa, CA, USA) for endovascular repair (EVAR) of @entity1028 ( @entity1028 ). MATERIALS AND METHODS: This retrospective multicentre study included 36 @entity1 (median age, 73.6  year) with @entity1028 (mean diameter, 5.65  cm) treated with the Ovation stent graft and followed up for at least 2  years. Safety and effectiveness of the Ovation stent graft were evaluated. Indications for EVAR were the following: AAA >= 5  cm, neck length >= 7  mm, angulation  <=60   and diameter <30  mm; the presence of neck calcification and @entity715 was not considered a contraindication; distal iliac landing zone length of 10  mm, and diameter between 5 and 20  mm. @entity1 were treated under a common protocol, including clinical and imaging follow-up at discharge, 30  days, 6  months, and annually for 5  years. Adverse events, clinical and imaging data and possible re-intervention were recorded. RESULTS: The Ovation stent graft was implanted successfully in 36 @entity1 (100  %). None of the @entity1 required conversion to open surgery, and none presented with an @entity1756 . Endograft stent @entity174 or migration was not observed in any case. No type I, III or IV @entity1070 were observed; in 12 @entity1 (33.3  %), a @entity1070 was noted, in one case with sac enlargement but not treated due to concomitant comorbidities and the @entity1 's decision. CONCLUSIONS: The 2-year results of the Ovation Abdominal Stent Graft System demonstrate excellent safety and effectiveness in the treatment of @entity1 with @entity1028 , particularly in those with challenging anatomical characteristics.
