Ventriculoatrial (VA) shunts are commonly used as a second-line treatment of hydrocephalus when the peritoneum is an unsuitable site for the distal catheter. Many centres now utilise ultrasound and interventional radiology techniques to aid placement of the distal catheter. The purpose of this study was to conduct a contemporary audit of VA shunting in children using interventional radiology techniques for placement of the distal catheter. ⋯ VA shunting provides a viable second-line option for shunt placement in complex hydrocephalus. The causes of shunt failure (blockage, infection and equipment failure) are similar to VP shunting though shunt survival rates are inferior to VP shunts. Ultrasound guided VA shunt placement provides a relatively safe, second-line alternative to the placement of a ventriculoperitoneal shunt when this route is unsuitable.

Painful neuromas can limit function and decrease quality of life. Although management of traumatic neuromas in adults is well represented in the literature, traumatic neuromas are seen less frequently in children and adolescents, and their management is underrepresented in the literature. We present a sample of our clinical experience with painful pediatric neuromas and describe the surgical management and clinical outcomes of these cases. ⋯ It is important for clinicians to recognize that pediatric patients develop painful neuromas following nerve trauma and to understand the neurophysiologic basis for their management. Our report demonstrates that many of the techniques that we use for neuroma repair in adults are applicable in the pediatric population.

We hypothesized that by using coronal MRI, Chiari I malformation could be more precisely diagnosed, would provide simple anatomic landmarks, would provide information regarding asymmetry of hindbrain herniation, and would be a better method for analyzing the tonsillar herniation postoperatively when the opisthion has been removed. ⋯ Sagittal MRI overestimates the degree of tonsillar ectopia in patients with Chiari I malformation. Misdiagnosis may occur if sagittal imaging alone is used. The cerebellar tonsils are paramedian structures, and this should be kept in mind when interpreting midline sagittal MRI.

There are no reliable noninvasive methods of monitoring ICP. Most assessments are made by indirect measures and are difficult to follow over time. Invasive studies can be used but up until now have required in-hospital transcutaneous measurements. Accurate ICP recordings over longer periods of time can be very valuable in timing different surgical procedures in syndromal cases. This case shows that telemetric ICP monitoring can be used for long-term follow-up in patients that may need repeated surgeries related to their craniosynostosis condition. ⋯ This "noninvasive" way of recording ICP is a feasible and helpful tool in decision-making and intervening in patients with craniosynostosis.

High-velocity trauma with acceleration/deceleration forces turns into shear stress over lenticulostriate or anterior choroidal arteries that lead to basal ganglia hemorrhage. Traumatic basal ganglia hematoma has rarely been described in pediatric population. The aim of this study was to present our clinical series of pediatric patients with traumatic basal ganglia hematoma and to analyze the prognostic indicators of traumatic basal ganglia hematoma. ⋯ Traumatic basal ganglia hematomas are unique and different from other kind of intracerebral hematomas. The eloquent nature of basal ganglia makes it more vulnerable to head trauma. Mechanism of injury, energy and velocity of injury are the most important prognostic criteria. Post-traumatic phase of injury should be carefully observed in patients with TBGH, especially when mechanism and velocity of injury are severe and high.
