BACKGROUND AND PURPOSE Preclinical studies showed that thrombus permeability improves recombinant tissue-type plasminogen activator (r-tPA) efficacy. We hypothesize that thrombus permeability estimated from radiological imaging is associated with improved recanalization after treatment with intravenously administered r-tPA (r-tPA) and with better functional outcome. METHODS We assessed thromb...

the results of two key clinical trials assessing the clinical efficacy of endovascular management in acute ischemic stroke were presented at the annual meeting of the International Stroke Conference (ISC) in Honolulu. The trials, SYNTHESIS expansion and IMS-III, had received great attention from many neurologists and neurointerventionalists, as they were multicenter, randomized, controlled tria...

BACKGROUND AND PURPOSE Tissue plasminogen activator (tPA) is a standard therapy for acute ischemic stroke (AIS) but only limited data are noted in Taiwan. The purpose of this study was to assess the safety, feasibility, and efficacy of treatment in a community hospital setting. METHODS We retrospectively reviewed the medical records of all patients who had received intravenous tPA therapy fro...

Patients with severe stroke due to acute large cerebral artery occlusion are likely to be severely disabled or dead without timely reperfusion. Previously, intravenous tissue plasminogen activator (IV-TPA) within 4.5 hours after stroke onset was the only proven therapy, but IV-TPA alone does not sufficiently improve the outcome of patients with acute large artery occlusion. With the introductio...

BACKGROUND Tissue plasminogen activator (tPA) is used emergently to dissolve thrombi in the treatment of fulminant pulmonary embolism. Currently, there is a relative contraindication to tPA in the setting of traumatic or prolonged cardiopulmonary resuscitation > 10 minutes because of the risk of massive hemorrhage. METHODS Our single-center, retrospective study investigated patients experienc...

BACKGROUND AND PURPOSE Race/ethnic-related differences in safety of intravenous thrombolytic therapy have been shown in patients with myocardial infarction, but not studied in ischemic stroke. METHODS Using data from the Get With The Guidelines (GWTG)-Stroke program (n=54 334), we evaluated differences in risk-adjusted bleeding rates (any, symptomatic intracerebral hemorrhage [sICH], serious ...

BACKGROUND Disseminated intravascular coagulation (DIC) is a pathological disturbance of the complex balance between coagulation and anticoagulation that is precipitated by vascular injury, acidosis, endotoxin release and/or sepsis and characterized by severe bleeding and excessive clotting. The innately low levels of coagulation factors found in newborn infants place them at extremely high ris...

Computed tomography (CT) is the current standard for time-critical decision-making in stroke patients, informing decisions on thrombolytic therapy with tissue plasminogen activator (tPA), which has a narrow therapeutic index. We aimed to develop a CT-based method to directly visualize cerebrovascular thrombi and guide thrombolytic therapy. Glycol-chitosan-coated gold nanoparticles (GC-AuNPs) we...

BACKGROUND Acute vertebrobasilar occlusion remains a disease with a high mortality even after treatment by local intra-arterial fibrinolysis. Adjunctive treatment with platelet glycoprotein IIb/IIIa receptor inhibitors such as abciximab may facilitate recanalization and improve the neurological outcome. Results after treatment of 3 patients by combined intravenous abciximab and local intra-arte...
