title: Intracranial Aneurysms in Children: The Role of Stenting and Flow-Diversion.
abstract: OBJECTIVE
  To report a single-center experience in the endovascular management of cerebral aneurysms in children with stenting and flow-diversion techniques.
  
  
  METHODS
  During a 7-year period, 5 male patients with six intracranial aneurysms (IA) were treated by endovascular therapy with stenting or flow-diversion. The average age was 11 years (range 6-18 years).
  
  
  RESULTS
  The etiology of the aneurysms was vasculopathic in 3 cases (50%), traumatic in 2 patients (33.3%), and idiopathic in 1 case (16.7%). Two-thirds of the aneurysms were giant in size. The aneurysms were most frequently located in the anterior circulation (66.7%). Fifty percent of the aneurysms were treated with stenting and coiling, and 50% were treated with flow-diversion stents alone. After treatment, occlusion was graded as: partial in five aneurysms (88.3%) and complete in 1 case (16.7%). Most cases (83.3%) had a good outcome after the procedure. During follow-up, most aneurysms had progressive occlusion (80%), while the rest were unchanged (20%). Most stents and flow-diverter devices remained patent (80%). However, one Pipeline flow-diverter device in the Anterior cerebral artery (ACA) A2 segment had an asymptomatic occlusion.
  
  
  CONCLUSIONS
  In this series, device-assisted endovascular techniques were a relatively safe and effective method of treatment of pediatric aneurysms. However, continued follow-up is required after treatment, because there are unsolved issues regarding the durability of flow-diverters and stents.
