Effects of attenuation and thrombus age on the success of ultrasound and microbubble-mediated thrombus dissolution.
The purpose of this study was to examine the effects of applied mechanical index, incident angle, attenuation and thrombus age on the ability of 2-D vs. 3-D diagnostic ultrasound and microbubbles to dissolve thrombi. A total of 180 occlusive porcine arterial thrombi of varying age (3 or 6 h) were examined in a flow system. A tissue-mimicking phantom of varying thickness (5 to 10 cm) was placed ...
متن کاملMicrobubble Mediated Thrombus Dissolution with Diagnostic Ultrasound for the Treatment of Chronic Venous Thrombi
BACKGROUND Central venous catheter (CVC) thrombi result in significant morbidity in children, and currently available treatments are associated with significant risk. We sought to investigate the therapeutic efficacy of microbubble (MB) enhanced sonothrombolysis for aged CVC associated thrombi in vivo. METHODS AND RESULTS A model of chronic indwelling CVC in the low superior vena cava with th...
متن کاملDissolution of an apical thrombus by apixaban in a patient with old anteroseptal myocardial infarction
A 55-year-old male patient with a history of anterior MI was followed-up in our outpatient clinic. He did not have atrial fibrillation (AF), and the ejection fraction was 45%. MI occurred 6 years ago, and warfarin has been previously prescribed for LVT. However, he had gastric bleeding at the follow-up while he was using warfarin and acetylsalicylate. At the time of gastric bleeding, INR was 7,...
متن کاملDissolution of mural thrombus by specific thrombin inhibition with r-hirudin: comparison with heparin and aspirin.
BACKGROUND The presence of residual mural thrombus may predispose to recurrent thrombotic events in acute coronary syndromes. The purpose of this study was to evaluate the effects of antithrombotic and antiplatelet agents on a preformed, fresh mural thrombus during growth of thrombus. METHODS AND RESULTS A fresh mural thrombus was formed by perfusing severely injured arterial wall with porcin...
متن کاملStudy on In-vivo Measuring Method of Solubility for Cerebral Thrombus Dissolution
A cerebral thrombus or blood clot might cause cerebral stroke and even decease if the clot could not be dissolved within several hours after it was formed. This paper presents a fundamental study on development of a new type of mechanical micro stirrer for assisting the dissolution of the thrombus with a few amount of thrombolytic agent. The micro stirrer is made of a slight beam embedded with ...
