BACKGROUND AND PURPOSE In spite of the advent of thrombolytic therapy, CT-perfusion imaging is currently not fully used for clinical decision-making and not included in published clinical guidelines for management of ischemic stroke. We investigated whether lesion volumes on cerebral blood volume (CBV), cerebral blood flow (CBF), and mean transit time (MTT) maps predict final infarct volume and...

Based on exclusion criteria in the landmark NINDS-rtPA trial, current expert consensus guidelines preclude the use of intravenous recombinant tissue plasminogen activator (IV rtPA) in acute ischemic stroke (AIS) patients with intracranial neoplasm. There are only 3 published cases of administration of IV rtPA to AIS patients with intracranial neoplasms in the literature. Two of these published ...

Introduction: Intravenous Tissue Plasminogen Activator (rTPA) is used to treat acute ischemic stroke (AIS). Early recanalization from this leads to better stroke outcomes, but the exact mechanism remains unknown. To clarify this, we correlated tissue perfusion and functional outcomes in acute stroke patients (AIS) who received rTPA to resting state default mode network (DMN) and task-positive (...

BACKGROUND Effective anticoagulation routinely precludes patients from receiving intravenous thrombolysis with recombinant tissue plasminogen activator to reverse severe symptoms of ischemic stroke. We report what we believe to be the first case of ischemic stroke successfully treated with recombinant tissue plasminogen activator after antagonizing dabigatran with the monoclonal antibody idaruc...

To continue to improve timely access to intravenous (IV) recombinant tissue plasminogen activator (rtPA) for more patients with acute ischaemic stroke (AIS), barriers to treatment are being addressed and new processes are being introduced. Two recent articles have highlighted how implementing new processes to improve access to, and timeliness of, thrombolysis can lead to economic as well as soc...

BACKGROUND AND PURPOSE Acute ischemic stroke patients are infrequently treated with recombinant tissue plasminogen activator (rtPA). We present unique population-based data regarding the eligibility of ischemic stroke patients for rtPA treatment. METHODS All ischemic strokes presenting to an emergency department (ED) within a biracial population of 1.3 million were identified. The patient was...

Myxoma may cause systemic embolization and frequently presents as ischemic stroke. There has been debates whether it is safe to use recombinant tissue plasminogen activator (rt-PA) in patients with cardiac myxoma who are presented with ischemic stroke at emergency department. we describe a young case of atrial myxoma with initial presentation of acute cerebral infarction symptoms who was treate...

Low-toxicity magnetic nanocarriers (MNCs) composed of a shell of poly [aniline-co-N-(1-one-butyric acid) aniline] over a Fe(3)O(4) magnetic nanoparticle core were developed to carry recombinant tissue plasminogen activator (rtPA) in MNC-rtPA for targeted thrombolysis. With an average diameter of 14.8 nm, the MNCs exerted superparamagnetic properties. Up to 276 μg of active rtPA was immobilized ...

Although intravital microscopy models of thrombosis in mice have contributed to dissect the mechanisms of thrombus formation and stability, they have not been well adapted to study long-term evolution of occlusive thrombi. Here, we assessed the suitability of the dorsal skinfold chamber (DSC) for the study of thrombolysis and testing of thrombolytic agents by intravital microscopy. We show that...

Rivaroxaban, a novel direct factor Xa inhibitor with consistent anticoagulant properties, was found to be safer and equally effective as warfarin in the prevention of embolic stroke in patients with nonvalvular atrial fibrillation [1, 2] . Effective anticoagulation predisposes to bleeding and represents a contraindication for intravenous thrombolysis (IVT) with recombinant tissue plasminogen ac...
