Ten to 40% of children operated on for a posterior fossa tumour require a further surgical procedure for the management of a persisting active ventricular dilation. The management of this kind of hydrocephalus is still controversial. ⋯ Post-operative ETV should be considered the best option to treat persistent hydrocephalus after the removal of posterior fossa tumours.

Venous hypertension is emerging as a significant contributor to intracranial pressure in children with syndromic craniosysnostosis. This is associated with jugular foramen stenosis or atresia and with the development of collateral emissary veins. We demonstrate how computed tomography venography can document the prevalence of these emissary veins and how their visualisation plays an important role in operative planning. ⋯ Patients with syndromic craniosynostosis often demonstrate abnormal venous anatomy, which can have serious consequences on craniofacial surgery, especially when a posterior decompression is being considered. Based on these findings, the authors assert that those children with some syndromic craniosynostosis being considered for surgery should undergo venographic studies as part of their pre-operative evaluation.
