    Flow diversion (FD) was successfully performed in four male patients with ischemia-onset vertebral artery dissecting aneurysms (VADA).

  • 2

    All patients exhibited O’Kelly–Marotta grade C occlusion at six-month follow-up, indicating effective flow remodeling after FD treatment.

  • 3

    No complications, recurrent cerebral infarction, or aneurysmal rupture occurred in any of the patients following FD placement.

  • 4

    FD may be a viable treatment option for selected cases of ischemia-onset VADA, potentially reducing the risk of embolic events.

  • 5

    The study highlights the need for further research on the efficacy of FD in managing ischemia-onset VADA due to limited existing evidence.
