Retrospective comparative study of 80 consecutive patients treated with either anterior cervical discectomy fusion (ACDF) or anterior cervical corpectomy fusion (ACCF) for multi-level cervical spondylosis. To compare clinical outcome, fusion rates, and complications of anterior cervical reconstruction of multi-level ACDF and single-/multi-level ACCF(More)
BACKGROUND Intradural filum terminale arteriovenous fistulas (AVFs) are uncommon. We report two cases of this rare entity in which we used indocyanine green (ICG) videoangiography to identify the fistulous connection of each lesion. CASE DESCRIPTION Two male patients presented with unresolved lower extremity weakness and paresthesias following lumbar(More)
Knowledge about the molecular mechanisms of neuronal survival following ischemia is crucial to the development of therapeutic interventions for victims of stroke. Previous research in our laboratory has implicated nuclear factor-kappaB (NF-kappaB) as contributing to neuronal survival in response to toxic or ischemic brain insult, with in vivo models having(More)
BACKGROUND AND PURPOSE Patients with posterior circulation strokes have been excluded from recent randomized endovascular stroke trials. We reviewed the recent multicenter experience with endovascular treatment of posterior circulation strokes to identify the clinical, radiographic, and procedural predictors of successful recanalization and good(More)
Aneurysms that involve the internal carotid artery and posterior communicating artery junction and incorporate a fetal posterior cerebral artery are known as fetal posterior communicating artery aneurysms. We report the outcomes of four patients with fetal posterior communicating artery aneurysms who underwent treatment with the pipeline embolization device(More)
Animal models of cerebral infarction are crucial to understanding the mechanisms of neuronal survival following ischemic brain injury and to the development of therapeutic interventions for victims of all types of stroke. Rodents have been used extensively in such research. One rodent model of stroke utilizes either permanent or temporary occlusion of the(More)
Deep arteriovenous malformations of the basal ganglia and thalamus have an aggressive natural history and present a therapeutic challenge. More often than not, these lesions are deemed "inoperable" and are treated expectantly or with stereotactic radiosurgery. In some cases, clinical details combined with an opportune route of access dictate surgical(More)
BACKGROUND Ventriculoperitoneal shunting is one of the most commonly performed neurosurgical procedures. Typically, for insertion of the peritoneal catheter, a mini-laparotomy technique is used. Although generally safe, it can be cosmetically undesirable and time consuming. Complications include malpositioning, bowel injury, and delayed hernias.(More)
INTRODUCTION High intracranial compliance states requiring negative pressure drainage, otherwise known as low-pressure hydrocephalus syndromes, are rare conditions. The use of siphoning, enabled by revision to an adjustable shunt without an anti-siphon device, has been largely unexplored in low-pressure hydrocephalus. METHODS Three patients with presumed(More)
PSs placed by a spinal surgical fellow (SSF) without prior experience under Attending Spinal Consultant (ASC) supervision from two tertiary spinal centers in Australia were investigated. All patients had postoperative radiographic studies, X-ray (XR) and/or computed tomography (CT), which were graded by two blinded and independent observers. Screws were(More)
