Dual frequency ultrasound-enhanced tissue plasminogen activator thrombolysis in an in vitro human clot model
Introduction: Stroke causes death and disability in patients throughout the world. At present, the only FDA- approved drug for ischemic stroke is recombinant tissue plasminogen activator (rt- PA). Unfortunately, rtPA can cause intracerebral hemorrhage and must use within limited time window (within 3-4.5 hour after onset of stroke). Ultrasound with rtPA loaded liposomes (rtPA_L...
متن کاملThrombolysis with low dose tissue plasminogen activator.
Two cases of vena caval thrombosis in infants were successfully treated with low dose (0.01-0.05 mg/kg/hour) local infusions of tissue plasminogen activator after conventional anticoagulant treatment had been unsuccessful. This approach is useful for clots associated with indwelling intravascular catheters, and a low dose infusion of tissue plasminogen activator as a regional application is rec...
متن کاملCoronary thrombolysis with recombinant human tissue-type plasminogen activator.
The thrombolytic potency and myocardial infarct--sparing potential of recombinant tissue-type plasminogen activator (rt-PA) were studied in electrocardiographically monitored, open-chest, anesthetized dogs. Localized coronary thrombosis was produced in the left anterior descending artery by endothelial injury and instillation of thrombin and fresh blood. After 2 hr of stable thrombotic occlusio...
متن کاملLow-dose tissue plasminogen activator thrombolysis in children.
PURPOSE To compare results of low-dose tissue plasminogen activator (TPA) in children with arterial and venous thrombi relative to standard published dosing. METHODS Subjects consisted of all consecutive children with objectively confirmed thrombi for whom TPA thrombolysis was clinically ordered by the authors. Initial dosing used published standard dose (0.1-0.5 mg/kg per hour). With experie...
متن کاملEffect of ultrasound on tissue-type plasminogen activator-induced thrombolysis.
BACKGROUND The efficacy of fibrinolytic therapy is limited by the small surface area of the clot that is available for the binding of the thrombolytic agent, such as tissue-type plasminogen activator (t-PA). We hypothesized that exposure of the clot to ultrasound during thrombolytic treatment could enhance lysis through perturbation of the thrombus, which would expose additional fibrin binding ...
