PURPOSE: To present the performance and safety of the Treovance stent graft for endovascular aortic aneurysm repair in a "real-world" patient cohort. METHODS: Patients from 2 centers, deemed unfit for open repair, were electively treated with the Treovance endograft. Clinical preoperative, operative, and up to 1-year postoperative follow-up data of patients were retrospectively analyzed. RESULTS: This study included 46 patients with abdominal aortic aneurysm (44 male), mean age of 78 years ± 8 standard deviation (SD; range: 58-93 years). All met the manufacturer's recommended anatomical requirements: average maximum sac diameter 63 mm ± 10 SD (range: 52-86 mm), proximal neck length 29 mm ± 12 SD (range: 11-60 mm), and neck angulation 30° ± 21 SD (range: 0°-70°). Fourteen had moderate to severe iliac tortuosity. A primary technical success rate of 80% was achieved (100% assisted primary technical success rate): 7 patients required adjunctive procedures intraoperatively and 2 successful treatments for type I endoleaks, which occurred within 24 hours postoperatively. There was 100% survival at 1-year follow-up; however, 4 (8.7%) patients required reintervention: 1 for a type I endoleak, 2 for limb stenosis, and 1 for a type II endoleak with an enlarging sac. No other device-related complications were identified. Reintervention and complication rates in hostile versus nonhostile anatomies were not statistically significant ( P = .28 and P = .42, respectively). CONCLUSION: The Treovance stent graft has a comparable safety profile to other next-generation stent grafts during the first year after endovascular aneurysm repair, which provides a rationale for further interrogation of its outcomes through clinical trials.
