BACKGROUND AND PURPOSE Neurologic and developmental outcomes of asphyxiated, term neonates are difficult to predict applying clinical or laboratory criteria. In this study, we investigated the association of MR spectroscopy (MRS) results with neurodevelopmental status at age 12 months. METHOD Thirty-one term neonates, who were enrolled in a prospective(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)
Carotid cavernous fistulae (CCF) are dangerous entities that may cause progressive cranial neuropathy, headache and blindness. Endovascular therapy for CCF is the treatment of choice and can be accomplished with minimal morbidity, but optimal treatment strategies vary according to CCF anatomy. We aimed to define a tailored endovascular treatment algorithm(More)
Flow-diverting stents have been associated with embolic and hemorrhagic complications, but the rate of procedure-related microemboli is unknown. Using transcranial Doppler sonography, we measured the rate of microemboli in 23 patients treated with flow-diverting stents. Patients received preprocedural dual antiplatelet medications and intraprocedural(More)
BACKGROUND AND PURPOSE Cerebral bypass grafts may develop generalized graft narrowing or focal stenosis during the perioperative period or later. Endovascular techniques such as PTA and stent placement of graft vessels are potential treatment options. Our objective was to review the safety, indications, technique, and results of endovascular management of(More)
BACKGROUND Loeys-Dietz syndrome (LDS) is an autosomal dominant connective tissue disorder characterized by extensive arterial aneurysms. The successful clipping of intracranial aneurysms in patients with LDS has been reported in a limited number of patients but endovascular treatment of intracranial aneurysms in LDS has never before been described. The(More)
FPCT and navigation software on contemporary fluoroscopic units perform imaging of a quality comparable with conventional CT. They can accurately guide percutaneous procedures, providing live instrument visualization and the capability to re-image without patient transfer. FPCT navigation was used in the placement of a ventricular drain in a 62-year-old(More)
Diffusion-weighted imaging (DWI) can help to diagnose acute ischemic stroke. Other nonischemic disorders may show abnormal signals with DWI. The authors report two cases of Wernicke encephalopathy with DWI signal changes in characteristic midline locations, one with reduction in apparent diffusion constant and one without. DWI abnormalities may suggest(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 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)
