Abstract
Early and 1-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. Retrospective site-reported data from the first 101 elective cases (2010-2014) from 4 UK centers were studied to evaluate patient demographics, aneurysm morphology, clinical success, and 1-year outcomes in patients undergoing fenestrated aneurysm repair with the custom-made Anaconda device. 101 fenestrated grafts (median age 76, 85% male) were implanted with a total of 255 fenestrations (196 renal arteries, 48 superior mesenteric artery, and 11 celiac arteries) with 3% mortality, 98.4% target vessel patency (TVP) at 30day follow-up. Although 15 type I or III endoleaks were demonstrated at completion angiography, all 10 type Ia endoleaks resolved spontaneously. Survival by Kaplan-Meier analysis was 97% and 91% at 1 month and 1 year, respectively; with 75.8% showing reduction in abdominal aortic aneurysm diameter and only 1 patient with sac expansion. Freedom from loss of TVP was 97.6%. Custom-made fenestrated Anaconda devices demonstrate low procedural mortality and a high rate of technical and clinical success at 30days and 1 year.
