Abstract
PURPOSE: The ventriculoperitoneal (VP) shunt has become the procedure of choice for treatment of idiopathic intracranial hypertension (IIH). We aimed to assess the efficacy of frameless stereotactic placement of VP shunts for the management of medically resistant IIH in children and to assess the role of gender and obesity in the aetiology of the condition. METHODS: This is a retrospective analysis of the case notes of 10 patients treated surgically at the University Hospital of Wales in Cardiff, from May 2006 to September 2012. RESULTS: VP shunts were successful in relieving headache, papilloedema and stabilising vision. No sex predilection was identified, and increased BMI was a feature throughout the population, regardless of age. CONCLUSIONS: Neuronavigated VP shunt insertion is an effective mode of treatment for medically resistant IIH in children. The aetiological picture in children does not seem to be dominated by obesity, as in adults. Literature on childhood IIH is sparse, and larger scale, comparative studies would be of benefit to treating clinicians.
