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 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 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)
This is the first in a set of documents intended to standardize techniques, procedures, and practices in the field of endovascular surgical neuroradiology. Standards are meant to define core practices for peer review, comparison, and improvement. Standards and guidelines also form the basic dialogue, reporting, and recommendations for ongoing practices and(More)
BACKGROUND AND PURPOSE Multichannel phased-array head coils are undergoing exponential escalation of coil element numbers. While previous technical studies have found gains in SNR and spatial resolution with the addition of element coils, it remains to be determined how these gains affect clinical reading. The purpose of this clinical study was to determine(More)
BACKGROUND Symptomatic intracranial atherosclerotic disease (ICAD) worldwide represents one of the most prevalent causes of stroke. When severe, studies show that it has a very high risk for recurrent stroke, highlighting the need for effective preventative strategies. The mainstay of treatment has been medical therapy and is of critical importance in all(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)
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)
OBJECT The authors evaluated the prognostic significance of blood glucose level at admission (BGA) and change in blood glucose at 48 hours from the baseline value (CG48) in nondiabetic and diabetic patients before and after endovascular therapy for acute ischemic stroke (AIS). METHODS The BGA and CG48 data were analyzed in 614 patients with AIS who(More)
