Operative and one year outcomes of the custom-made fenestrated Anaconda® aortic stent graft - a UK multicentre study.
OBJECTIVES: Early and one year outcomes are presented for fenestrated endovascular aneurysm repair (FEVAR) of complex aortic aneurysmal disease with the custom-made Anaconda fenestrated stent graft in 101 patients. METHODS: Retrospective site-reported data from the first 101 elective cases (2010 to 2014) from four UK centres was studied to evaluate patient demographics, aneurysm morphology, clinical success and one year outcomes in patients undergoing fenestrated aneurysm repair with the custom-made Anaconda device. RESULTS: 101 fenestrated grafts (median age 76, 85% male) were implanted with a total of 255 fenestrations (196 renal arteries, 48 SMA, 11 coeliac arteries) with 3% mortality, 98.4% target vessel patency at 30 day follow-up. Although 15 type I or III endoleaks were demonstrated at completion angiography all 10 type 1a endoleaks resolved spontaneously. Survival by Kaplan-Meier analysis was 97% and 91% at one month and one year respectively; with 75.8% showing reduction in AAA diameter and only one patient with sac expansion. Freedom from loss of target vessel patency (TVP) was 97.6%. CONCLUSIONS: Custom-made fenestrated Anaconda devices demonstrate low procedural mortality and a high rate of technical and clinical success at 30 days and one year.
