BACKGROUND AND PURPOSE Patients undergoing intra-arterial therapy (IAT) for acute ischemic stroke receive either general anesthesia (GA) or conscious sedation. GA may delay time to treatment, whereas conscious sedation may result in patient movement and compromise the safety of the procedure. We sought to determine whether there were differences in safety(More)
BACKGROUND AND PURPOSE Endovascular techniques are frequently employed to treat large artery occlusion in acute ischemic stroke (AIS). We sought to determine the predictors and clinical impact of intracranial hemorrhage (ICH) after endovascular therapy. METHODS Retrospective analysis of consecutive patients presenting to 13 high volume stroke centers with(More)
OBJECTIVE To summarize and classify the evidence for the use of endovascular techniques in the treatment of patients with acute ischemic stroke. METHODS Recommendations previously published by the American Heart Association (AHA) (Guidelines for the early management of adults with ischemic stroke (Circulation 2007) and Scientific statement indications for(More)
BACKGROUND AND PURPOSE MR imaging of moving patients can be challenging and motion correction techniques have been proposed though some have associated new artifacts. The objective of this study was to semiquantitatively compare brain MR images of moving patients obtained at 1.5T by using partially radial and rectilinear acquisition techniques. MATERIALS(More)
BACKGROUND Despite some limitations, a perfusion/diffusion mismatch can provide a working estimate of the ischemic penumbra in hyperacute stroke and has successfully been used to triage patients. PURPOSE To evaluate whether the addition of magnetic resonance imaging (MRI) to clinical and non-contrast computed tomography (CT) data alters diagnosis and(More)
OBJECTIVES/HYPOTHESIS Superior semicircular canal dehiscence (SSCD) syndrome has been a topic of much interest since its first description a decade ago. The symptoms of vertigo, autophony, and Tullio phenomenon have been well described as has the utility of surgical repair. The standard approach described for surgical repair of this problem has been to(More)
Low-flow vascular malformations are congenital lesions secondary to errors in the development of veins, capillaries or lymphatics. The majority of these lesions are sporadic although association with heritable syndromes does occur. Patients with these lesions should be treated and evaluated by a multidisciplinary team comprising medical, radiologic and(More)
OBJECTIVE To review the clinical presentation, surgical techniques, and outcomes of the transmastoid extradural-intracranial (TMEDIC) approach for the treatment of transtemporal meningoencephalocele. HYPOTHESIS The TMEDIC is a safe and effective approach to repair meningoencephalocele originating from the middle or posterior cranial fossa. STUDY DESIGN(More)
BACKGROUND Reperfusion therapy for acute ischemic stroke (AIS) is rapidly evolving, with the development of multiple endovascular modalities that can be used alone or in combination. OBJECTIVE To determine which pharmacologic or mechanical modality may be associated with increased rates of recanalization. METHODS A cohort of 1122 patients with AIS(More)
BACKGROUND AND PURPOSE We report the incidence and risk factors for contrast-induced nephropathy after the use of iodinated contrast for endovascular treatment of acute ischemic stroke. METHODS A retrospective chart review was performed in 194 consecutive patients who underwent endovascular treatment for acute ischemic stroke between January 2006 and(More)
