The Spectrum of Intracranial Aneurysms in Pediatrics

Abstract

Intracranial aneurysms are rare in children, accounting for merely 0.5 - 4.6% of all aneurysms. Several characteristics distinguish them from aneurysms in adults: male predominance; higher incidence of unusual location, such as peripheral or posterior circulation; and a greater number of large and giant aneurysms. These unique features can be attributed to the higher incidence of traumatic, infectious, developmental, and congenital lesions. Subarachnoid hemorrhage is not the exclusive mode of presentation; neuro-compressive signs and symptoms are also frequently seen. The treatment of intracranial aneurysms in pediatrics is dictated by their unusual pathology and liability to rehemorrhage. Although direct clipping has been the standard surgical technique, certain obsolete or innovative procedures should also be considered, such as entrapment, proximal occlusion, and endovascular embolisation, or even, in some cases, the noninvasive treatment of “watch and wait” for a spontaneous thrombosis. Six representative cases from King Faisal Specialist Hospital and Research Centre are reviewed. They reflect the diversity of the problem and the multi-disciplinary approach to the treatment.
