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)
Atrial fibrillation (AF) is a frequent cause of acute ischemic stroke that results in severe neurological disability and death despite treatment with intravenous thrombolysis (intravenous recombinant tissue plasminogen activator [rtPA]). We performed a retrospective review of a single-center registry of patients treated with intravenous rtPA for stroke. The(More)
BACKGROUND There are multiple clinical and radiographic factors that influence outcomes after endovascular reperfusion therapy (ERT) in acute ischemic stroke (AIS). We sought to derive and validate an outcome prediction score for AIS patients undergoing ERT based on readily available pretreatment and posttreatment factors. METHODS The derivation cohort(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)
In Kaohsiung City, dengue fever subsided for two years after the 1987-1988 epidemic. The main reason that it recurred was due to late diagnoses of the dengue fever in patients because of mild or atypical clinical presentations. The first patient contracted dengue fever from Thailand in mid-May, 1991. The disease then spread among his co-workers. Dengue(More)
PURPOSE Advanced neuroimaging techniques may improve patient selection for endovascular stroke treatment but may also delay time to reperfusion. We studied the effect of advanced modality imaging with CT perfusion (CTP) or MRI compared with non-contrast CT (NCT) in a multicenter cohort. MATERIALS AND METHODS This is a retrospective study of 10 stroke(More)
BACKGROUND AND PURPOSE Technological advances have helped to improve the efficiency of treating patients with large vessel occlusion in acute ischemic stroke. Unfortunately, the sequence of events prior to reperfusion may lead to significant treatment delays. This study sought to determine if high-volume (HV) centers were efficient at delivery of(More)
