Insights
Pediatric intracranial aneurysms are rare but differ from adult cases. Both endovascular and microsurgical treatments are effective, with endovascular therapy often preferred for complex pediatric aneurysms, leading to favorable outcomes.
Area of Science:
- Neurology
- Pediatric Neurosurgery
- Vascular Neurology
Background:
- Intracranial aneurysms are uncommon in children.
- Understanding their unique characteristics is crucial for effective management.
Purpose of the Study:
- To detail the clinical and radiological features of pediatric intracranial aneurysms.
- To evaluate therapeutic outcomes and guide treatment strategies.
Main Methods:
- Retrospective analysis of 24 pediatric patients (<14 years) treated over 23 years.
- Review of diagnosis, treatment modalities (endovascular, microsurgical, conservative), and outcomes.
Main Results:
- Posterior circulation and giant aneurysms were common (36% and 32%).
- Subarachnoid hemorrhage occurred in 46% of patients.
- 92% of patients achieved favorable outcomes with various treatments.
Conclusions:
- Pediatric intracranial aneurysms exhibit distinct features compared to adults, including higher rates of giant and posterior circulation aneurysms.
- Both endovascular and microsurgical approaches are effective.
- Endovascular therapy is often the optimal choice for complex pediatric aneurysms.
Purpose:
Intracranial aneurysms are relatively rare in the pediatric population. The objective of this study was to highlight the clinical and radiological features and the therapeutic outcome and clarify the choice of therapeutic strategies for pediatric intracranial aneurysms.
Materials And Methods:
Twenty-four consecutive children (age
Results:
There were nine (36%) patients with posterior circulation aneurysms and eight (32%) with giant aneurysms. Eleven (46%) patients presented with subarachnoid hemorrhage. Fifteen patients underwent endovascular treatment, and four received microsurgical therapy. Five patients were treated conservatively. Ninety-two percent (n=22) of the patients showed favorable outcomes.
Conclusions:
Pediatric intracranial aneurysms differ in many ways from those in adults: male predominance; high incidence of giant, dissecting, and fusiform aneurysms; high incidence of aneurysms in the posterior circulation; high incidence of spontaneous thrombosis; better Hunt-Hess grades at presentation; and better therapeutic outcome. For children with intracranial aneurysms, both microsurgical approaches and endovascular treatment were effective. For many complex aneurysms, endovascular therapy was the best choice.
