BACKGROUND The effort required to introduce simulation in neurosurgery academic programs and the benefits perceived by residents have not been systematically assessed. OBJECTIVE To create a neurosurgery simulation curriculum encompassing basic and advanced skills, cadaveric dissection, cranial and spine surgery simulation, and endovascular and(More)
Developmental venous anomalies (DVA) are among the most common congenital malformations of the cerebral angioarchitecture. Spontaneous thrombosis of this entity is rare, and our review of the literature found only 31 reported cases of symptomatic spontaneous thrombosis of developmental venous anomalies. Here, we report a unique case describing the(More)
CT angiography (CTA) is increasingly being utilized in the initial diagnosis of subarachnoid hemorrhage. While active bleeding from an intracranial aneurysm has been demonstrated on conventional angiography, CT angiogram findings of active aneurysmal hemorrhage are not well described. We present a case of an actively bleeding anterior communicating artery(More)
OBJECTIVE This study explores the usefulness of virtual simulation training for learning to place pedicle screws in the lumbar spine. METHODS Twenty-six senior medical students anonymously participated and were randomized into two groups (A = no simulation; B = simulation). Both groups were given 15 minutes to place two pedicle screws in a sawbones model.(More)
OBJECT The authors have previously reported on their early experience with sublaminar polyester bands in spine surgery. In this paper, the authors describe the use of sublaminar polyester bands in long-segment posterior instrumented spinal fusions from the upper thoracic spine to the ilium in 21 children and transitional adults with progressive(More)
We report two unusual cases of a 17-month-old boy with a previously undiagnosed lumbar dermal sinus tract terminating in an intradural dermoid cyst and holocord edema or syrinx, presenting with paraparesis and sphincter dysfunction secondary to an intramedullary abscess and a 26-month-old boy with a previously undiagnosed lumbar dermal sinus tract(More)
The authors present a unique case of a patient with communicating hydrocephalus and repeated ventriculoperitoneal shunt obstructions resulting from mucin-secreting enterogenous cell deposits at the cervicomedullary junction. Pathological examinations revealed that these cellular deposits lacked characteristic cystic architecture and the patient had no(More)
PURPOSE The authors assess the role of flexible hollow core CO2 laser system (Omniguide system) in resection of intraspinal lipomas. METHODS Eight patients with intraspinal lipomas were operated using an Omniguide laser system over a 22-month period. The age range varied between 6 months and 16 years. All of them had lipoma of the conus medullaris(More)
OBJECT Isolated cervical canal stenosis at the level of the atlas (C-1) is a rare cause of cervical myelopathy in the pediatric population. It has been associated with several genetic disorders including spondyloepiphysial dysplasia congenita, Down syndrome, and Klippel-Feil syndrome. The purpose of this study is to highlight the authors' experience with 4(More)
Surgical resection is the current standard of therapy for the treatment of arteriovenous malformation (AVM). Endovascular embolization is commonly used as an adjunct prior to surgical resection because it is believed to reduce the risk of intraoperative bleeding. Embolization has been associated with other complications including visual deficits, vessel(More)
