Paediatric vertebral artery aneurysms: a literature review
Intracranial aneurysms are rare but potentially devastating entities in the paediatric population. The prevalence in the literature varies from 1.0 to 1.8% of all intracranial aneurysms found in the general population.1 Between 1939 and 2005, 706 paediatric intracranial aneurysms were reported in the English literature.6 The frequency of paediatric vertebral artery (VA) aneurysms specifically is poorly defined in the literature. Generally, management for intracranial VA aneurysms is exclusion of the lesion from circulation while preserving adequate blood flow to the brain. Multiple treatment options are available, including surgery, endovascular treatment, coil embolization or parent artery occlusion; however, there is limited clinical evidence and guidelines regarding which approach is most optimal for which subset of patients. This review outlines the current literature and evidence base on the epidemiology, presentation, pathogenesis and treatment of paediatric VA aneurysms.
