Background/Objective: To report mid-term to long-term outcome data for endovascular aortic repair using the Ovation stent graft system (Endologix, Santa Rosa, CA) for the correction of abdominal aortic aneurysms (AAAs) in a single center. Methods: All patients treated with the Ovation stent graft between December 2011 and February 2018 were included. Patient demographics, anatomical and operative details, as well as follow- up data including complications, the need for further interventions, and mortality were recorded prospectively in an electronic dataset and analyzed. Results: A total of 99 patients (86.10% males; mean age 73.6 ± 7.26 years) were treated with the Ovation stent graft. The mean maximal aortic diameter was 53.7 ± 8.8 mm mm. The main indications for Ovation use were small iliac accesses and thrombus/calcification at the proximal neck level. The technical success rate was 93.06%. No perioperative reintervention or limb occlusion was reported. Two graft-related perioperative adverse events were recorded. At a mean follow up of 82.70 ± 40 months, cumulative late survival was 97.90%, 92.60%, 81.00%, 73.40%, 48.70%, and 45.10%, respectively, at 12, 24, 48, 60, 108, and 120 months. No AAA-related death was recorded. Actuarial freedom from reintervention rate was 97.90%, 95.70%, 92.10%, and 80.10%, respectively, at 12, 24, 60, 108, and 120 months; estimated freedom from conversion was 98.90%, 97.70%, and 95.20% at 24, 60, 108, and 120 months. Conclusions: The Ovation stent graft demonstrated durable AAA exclusion even in complex anatomies evidenced by successful aneurysm exclusion and mid- to long-term freedom from aneurysm-related mortality. However, in this series, the not insignificant graft-related adverse event rate suggested the need for structural improvements, which were implemented in the next-generation devices.

Purpose: This paper aims to describe a straightforward, efficient, and reliable technique to simplify cannulation maneuvers during aortic branched endograft repair. Technique: The suggested approach utilizes the Penumbra Neuron Select catheter, which combines diagnostic, sizing, and support capabilities in one. This has the potential to reduce procedural time and minimize the need for serial catheter and guidewire exchanges. Conclusions: The proposed technique offers a simple yet effective tool to mitigate the risk of vessel loss and injury, and to streamline complex aortic repair procedures.
