FEVAR with Anaconda achieved high technical success and mid-term vessel stability; excessive intra-aortic stent protrusion and sealing length independently increased target vessel instability.
Do excessive intra-aortic bridging stent protrusion and increased sealing length increase the risk of target vessel instability in patients undergoing FEVAR?
In FEVAR using the Anaconda system, excessive intra-aortic bridging stent protrusion and increased sealing length independently predict target vessel instability, emphasizing the need for precise geometric optimization during procedural planning.

Fenestrated endovascular aneurysm repair using the Anaconda stent-graft system demonstrates high technical success and mid-term freedom from TVI. Extended intra-aortic stent protrusion and sealing length, significantly impact TVI adversely. Optimizing bridging stent geometry may reduce re-intervention rates and improve outcomes in complex aortic repairs.Clinical ImpactThis study demonstrates that fenestrated endovascular aneurysm repair using the Anaconda custom-made fenestrated stent-graft system provides high technical success and durable mid-term target vessel stability in complex aortic aneurysm repair. Importantly, it identifies modifiable anatomical predictors-excessive intra-aortic bridging stent protrusion and increased sealing length-as independent risk factors for target vessel instability. These findings shift attention from device selection alone to precise geometric optimization of bridging stents during procedural planning and deployment. For clinicians, careful control of protrusion length and sealing configuration may reduce endoleaks and re-interventions. The innovation lies in linking quantitative vessel geometry to clinical outcomes, offering actionable parameters to improve durability in FEVAR.
