Long-term clinical follow-up of intracranial aneurysms treated with flow diverter devices: a bicentric retrospective study

Abstract

Beyond 18 months of follow-up, FDD treatment for intracranial aneurysms proves exceptional safety with no delayed complications, regardless of device type. However, the findings of this study also show 18 months as a critical threshold for complication risk assessment, a key implication that clinicians and researchers need to be aware of. The study also underscores the need for modified management strategies when multiple overlapping FDDs are deployed, which significantly increases the risk of delayed complications.
