Comparative Analysis of Bridging Stent Outcomes in Fenestrated and Branched Endovascular Aortic Aneurysm Repair

Type of Research: Single-center retrospective cohort studyKey Findings: Among 321 patients undergoing fenestrated and branched endovascular aortic repair (F/BEVAR) with 1171 bridging stent grafts (BSGs), overall primary patency remained high through mid-to long-term follow-up.Bard Lifestream stents had higher odds of primary patency loss on multivariable analysis (OR 3.83, 95% CI 2.05-7.04,P < 0.001).The left renal artery showed lower primary patency at 3 years, however, no significant differences were observed between fenestrations and directional branches.Take home Message: BSG patency after F/BEVAR remains excellent overall, although devicespecific differences were observed.Multicenter studies are needed to validate contemporary outcomes and guide optimal device selection. Table of Contents SummaryIn this single-center retrospective study of 321 patients undergoing F/BEVAR with 1171 bridging stent grafts (BSGs), overall primary patency was high across devices.Bard Lifestream stents were associated with higher odds of primary patency loss, while Bentley BeGraft Peripheral stents demonstrated favorable early results.No significant differences were observed between fenestrated and branched configurations.These findings underscore the durability of current bridging platforms and highlight the need for further evaluation of device-specific outcomes in contemporary practice.
