Background Abdominal aortic aneurysms pose a substantial clinical burden, and a significant proportion are not anatomically suitable for open repair or standard endovascular aneurysm repair ( EVAR ), instead requiring fenestrated EVAR ( fEVAR ). We sought to compare clinical outcomes and trends over time in patients undergoing fEVAR in Australia. Methods We conducted a retrospective analysis of all patients undergoing fEVAR at a tertiary referral centre between 2010 and 2015, including outcomes and complications, both as inpatients and after discharge. Results Thirty‐nine patients underwent fEVAR during the study period, with mean age of 75 years and mean aneurysm size of 61 mm. One hundred and thirty‐four target vessels were treated and inhospital mortality was 5% (two patients). There were nine inhospital, eight Type II and one Type III endoleaks. Ten patients suffered acute kidney injury, one of whom required dialysis. Mean follow‐up was 14.5 months (range: 0–46.7). Target vessel patency was 99.2% at follow‐up. There were six Type II endoleaks at follow‐up, and two patients died during the follow‐up period (of non‐aneurysm‐related causes). Conclusion fEVAR is an effective treatment with low morbidity and mortality, and we have demonstrated excellent survival and target vessel patency at a mean follow‐up of 14 months. Endoleak rates were low, despite the high complexity of the aneurysms treated.
