BACKGROUND The use of antithrombotic agents, including anticoagulants, antiplatelet agents, and thrombolytics has increased over the last decade and is expected to continue to rise. Although antithrombotic-associated intracranial hemorrhage can be devastating, rapid reversal of coagulopathy may help limit hematoma expansion and improve outcomes. METHODS(More)
BACKGROUND AND PURPOSE We aimed to investigate the feasibility and therapeutic effect of external counterpulsation (ECP) in ischemic stroke. METHODS The trial was a randomized, crossover, assessment-blinded, proof-of-concept trial. ECP treatment consisted of 35 daily 1-hour sessions. Patients were randomized to either early (ECP weeks 1 to 7 and no ECP(More)
BACKGROUND AND PURPOSE Efforts to increase the availability and shorten the time delivery of intravenous thrombolysis in patients with acute ischemic stroke carry the potential for tissue plasminogen activator administration in patients with diseases other than stroke, that is, stroke mimics (SMs). We aimed to determine safety and to describe outcomes of(More)
BACKGROUND AND PURPOSE External counterpulsation (ECP) improves coronary perfusion, increases left ventricular stroke volume similar to intraaortic balloon counterpulsation, and recruits arterial collaterals within ischemic territories. We sought to determine ECPs effect on middle cerebral artery (MCA) blood flow augmentation in normal controls as a first(More)
The Neurovascular Education and Training in Stroke Management and Acute Reperfusion Therapy (NET SMART) program for advanced practice nursing (APN) offers a first-of-its-kind, academic, postgraduate, fellowship program for APNs that is modeled after physician academic fellowship programs but supported by a flexible Internet-based platform.

BACKGROUND AND PURPOSE Shortening door-to-needle time may lead to inadvertent intravenous thrombolysis (IVT) administration in stroke mimics (SMs). We sought to determine the safety of IVT in SMs using prospective, single-center data and by conducting a comprehensive meta-analysis of reported case-series. METHODS We prospectively analyzed consecutive(More)
IMPORTANCE Cerebral microbleeds (CMBs) have been established as an independent predictor of cerebral bleeding. There are contradictory data regarding the potential association of CMB burden with the risk of symptomatic intracerebral hemorrhage (sICH) in patients with acute ischemic stroke (AIS) treated with intravenous thrombolysis (IVT). OBJECTIVE To(More)
BACKGROUND AND PURPOSE Recurrent hemodynamic and neurological changes with persisting arterial occlusions may be attributable to cerebral blood flow steal from ischemic to nonaffected brain. METHODS Transcranial Doppler monitoring with voluntary breath-holding and serial NIH Stroke Scale (NIHSS) scores were obtained in patients with acute middle cerebral(More)
BACKGROUND AND PURPOSE It is unknown how little flow velocity improvement is necessary to achieve recanalization and clinical recovery. We sought to investigate which flow velocity parameter was associated with complete recanalization/reperfusion and neurological improvement in patients receiving reperfusion therapies. METHODS Patients with proximal(More)
BACKGROUND AND PURPOSE Early deterioration can occur after acute stroke for a variety of reasons. We describe a hemodynamic steal and associated neurological deterioration, the reversed Robin Hood syndrome (RRHS). We aimed to investigate the frequency and factors associated with RRHS. METHODS Consecutive patients with acute cerebral ischemia underwent(More)
