N2 - OBJECTIVE: The aim of this study was to report outcomes of the BeGraft and BeGraft Plus as bridging covered stents in fenestrated and branched endovascular aneurysm repair (FB-EVAR).METHODS: Patients treated and followed in two institutions receiving at least one BeGraft or BeGraft Plus as bridging covered stent between January 2018 and July 2023 were included.RESULTS: A total of 765 target vessels (TVs) in 281 patients were aimed to be bridged with the BeGraft or BeGraft Plus. Target vessel technical success was 99.5% (761/765). Estimated TV patency at one and two years was 98.5 ± 0.5% and 96.7 ± 0.9%, respectively, with no difference between fenestrations and branches. Estimated freedom from TV related endoleak at one and two years was 98.5 ± 0.5% and 97.9 ± 0.6%, respectively. Estimated freedom from endoleak at two years was lower for TVs targeted with branches compared with TVs targeted with fenestrations (94.2 ± 1.9% vs. 99.7 ± 0.3%, respectively; p < .001). Estimated freedom from TV related re-intervention at one and two years was 97.7 ± 0.6% and 97.1 ± 0.7%, respectively. Estimated freedom from TV related re-intervention at two years was lower for TVs targeted with branches compared with TVs targeted with fenestrations (93.1 ± 2.0% vs. 99.0 ± 0.5%, respectively; p < .001). Estimated freedom from TV instability at one and two years was 96.8 ± 0.7% and 94.5 ± 1.1%, respectively. Estimated freedom from TV instability at two years was 96.0 ± 1.3% for fenestrations and 91.2 ± 2.2% for branches (p = .003).CONCLUSION: The BeGraft and BeGraft Plus covered stents showed good midterm outcomes as bridging covered stents in FΒ-EVAR. Branches showed higher instability rates compared with fenestrations. Branches showed similar patency rates to fenestrations.
