Clinical Report: Effects of Flow Diversion on Ischemic and Hemorrhagic Outcomes

Overview

Revise to specify the number of patients with recurrent embolic events and clarify if all had ischemia-onset VADA.

Background

Intracranial vertebral artery dissecting aneurysms (VADA) can lead to significant morbidity due to ischemic strokes and potential hemorrhagic events. While conservative management is often employed, some patients experience complications such as aneurysmal enlargement and recurrent ischemic events. The role of flow diversion in managing these cases remains underexplored, highlighting the need for further investigation into its efficacy and safety.

Data Highlights

Adjust table format for consistency and consider including more detailed outcomes.

Key Findings

  • Flow diversion was technically successful in all four cases.
  • All patients achieved O’Kelly–Marotta grade C occlusion at six-month follow-up.
  • No complications were reported post-procedure.
  • No recurrent cerebral infarctions or aneurysmal ruptures occurred during the follow-up period.
  • Dual antiplatelet therapy was initiated at least 7 days prior to the procedure.

Clinical Implications

The findings suggest that flow diversion may be a viable treatment option for selected patients with ischemia-onset VADA, potentially reducing the risk of serious complications. Clinicians should consider this approach in cases where conservative management fails to prevent aneurysmal enlargement or recurrent ischemic events.

Conclusion

Highlight the necessity for larger studies and suggest specific future research directions.
