An increasing number of children with Chiari I malformations are coming to the attention of neurosurgeons today, although a consensus on the surgical approach to these lesions has yet to be found. We present a retrospective analysis of posterior fossa decompression (PFD) performed at our institution on 96 patients from 1989 to 2001. Statistical analyses(More)
The object was to describe the clinical, radiologic, and pathologic features of astroblastomas in an unselected group of children who were treated in a single institution during an 11-year period. Eight children with astroblastomas of the brain were examined. Diagnosis was based on cell morphology, vascular attachment of the cell main process, lack of an(More)
Endoscopic third ventriculostomy (ETV) is considered by many authors the initial surgical procedure of choice for the treatment of non-communicant hydrocephalus. However, this procedure has early and late complications that neurosurgeons must be aware of when performing it. A retrospective study of infants and children treated with ETV at Children’s(More)
STUDY DESIGN A retrospective study was undertaken which evaluated the medical records and imaging studies of a subset of patients managed by the spine service at Jackson Memorial Hospital who were diagnosed with an esophageal perforation in the setting of spinal surgery. OBJECTIVE To assess the safety and efficacy of a sternocleidomastoid muscle flap in(More)
Pediatric intracranial aneurysms are exceedingly rare and account for less than 5% of all intracranial aneurysms. Open surgery to treat such aneurysms has been shown to be more durable than endovascular techniques, and durability of treatment is particularly important in the pediatric population. Over the past 2 decades, however, a marked shift in aneurysm(More)
The authors present the case of a 5-year-old girl with traumatic hydrocephalus secondary to a retroclival haematoma associated with atlanto-occipital dislocation (AOD) after a motor vehicle accident. Clinical history and neuroimaging of the patient are described. Computed tomography (CT) imaging of the head revealed a retroclival haematoma with secondary(More)
OBJECTIVE To analyze our institution's work-up for patients with a diagnosis of subdural haematoma (SDH) in order to determine how many of them are secondary to child abuse, as well as to examine their final functional outcome. METHODS Retrospective review of children under 2 years of age diagnosed as having SDH between 1995 and 2005. RESULTS A total of(More)
Patients with obstructive sleep apnea syndrome (OSAS) are at increased risk for cerebrovascular diseases. The underlying mechanisms remain obscure. It may occur through a reduction in cerebral vascular reactivity. Continuous positive airway pressure (CPAP) is effective in reducing the occurrence of apneas. We hypothesized that treatment with CPAP improves(More)
Spontaneous intracerebral hemorrhage in children is usually related to cerebrovascular conditions. Brain tumors presenting with spontaneous bleeding account for approximately 10% of intracranial hemorrhages in children. The occurrence of primitive central nervous system lesions in the Ewing sarcoma family of tumors (ESFT) not related to bone or metastatic(More)
The authors report on two children in whom an anomalous posterior fossa venous drainage pattern prevented safe posterior fossa decompression. Both patients had Chiari malformation Type I, multisutural craniosynostosis, and crowded posterior fossa structures. Both patients had been treated with ventriculoperitoneal shunts for hydrocephalus. Pfeiffer syndrome(More)
