INTRODUCTION Helical computed tomography angiography (CTA) has become an established technique for evaluating atherosclerosis of the cerebrovascular arteries. However, the role of CTA in penetrating and blunt trauma to the carotid and vertebral arteries is not well defined. We conducted a systematic literature review to determine the diagnostic accuracy of(More)
PURPOSE To examine the subgroup of patients with medically intractable epilepsy receiving temporal lobectomies who have pathologically verified mesial temporal sclerosis (MTS) and to determine the relation of demographic and clinical factors, results of diagnostic testing, and details of the surgical procedure with prognosis for achieving control of(More)
OBJECTIVE   Trigeminal neuralgia is rarely caused by arteriovenous malformations of the posterior fossa. Embolization of aberrant vessels can provide symptomatic relief; however, embolization is not always technically possible, and its effects can be temporary. Embolization of the nerve's blood supply could reduce its excitability and provide pain relief.(More)
BACKGROUND We sought to determine whether 16-slice multidetector CT angiography (CTA) has sufficient negative predictive value for use as the initial imaging examination for patients with suspected blunt carotid and vertebral artery injury (BCVI) and to estimate the positive predictive value of different screening criteria in assessing BCVI. STUDY DESIGN(More)
BACKGROUND The results of treatment of intracranial dural arteriovenous fistulas (DAVFs) since Onyx became available as an embolic agent at our institution is reported. An algorithm is presented for treatment of DAVFs with Onyx, and the role of endovascular transvenous, surgical, and radiosurgical approaches are presented. METHODS Thirty-two patients with(More)
Orbital apex injury is usually seen in multiply and severely injured patients who are subject to high-energy trauma. Orbital apex injury rarely occurs in isolation. By proximity, the face, the skull base, or their combination are the most likely regions to be injured in association with orbital apex trauma. The vast majority of these injuries occur as an(More)
BACKGROUND Parainfectious vascular events are a known complication of bacterial meningitis, typically occurring within two weeks of disease onset. Delayed vascular complications are rare. We present a case of progressive vasculopathy following bacterial meningitis. CASE DESCRIPTION A 20 year old woman developed progressive vasculopathy after successful(More)
BACKGROUND Brain arteriovenous malformations (BAVMs) are a frequent cause of pediatric hemorrhagic stroke, which frequently results in significant morbidity and mortality. OBJECTIVE To analyze the results of multimodality treatment for a consecutive series of pediatric patients with ruptured and unruptured BAVMs at a single institution. METHODS Forty(More)
BACKGROUND The design and conclusions of A Randomized Trial of Unruptured Brain Arteriovenous Malformations (ARUBA) trial are controversial, and its structure limits analysis of patients who could potentially benefit from treatment. OBJECTIVE To analyze the results of a consecutive series of patients with unruptured brain arteriovenous malformations(More)
Computed tomography has revolutionized the diagnosis and treatment planning of the acutely injured spine. In the cervical spine, its appropriate use can improve outcome and save money. Although there are no clinical prediction rules validated outside of the cervical spine, these proven capabilities have been extrapolated to the thoracolumbar spine.
