Active clinical trials for "Embolism"

The primary objective is to evaluate the efficacy (as measured by the rate of recurrent symptomatic Venous Thromboembolism [VTE] (i.e., Pulmonary thromboembolism [PE] and Deep Vein Thrombosis [DVT])) and safety of GSK576428 as the initial treatment in subjects with acute PE in an open-label design.

This study will test the hypothesis that patients with acute PE and dyspnea can safely inhale NO. The secondary hypothesis is that patients who are blinded to the inhaled NO concentration will sustain subjective improvement in their perception of dyspnea based upon their reported Borg dyspnea score, during inhalation of NO. Specific aims Test if patients with acute PE and shortness of breath of severity ≥ 5 on a 0-10 scale called the Borg score can have inhaled nitric oxide administered via nasal cannula or face mask in a titration protocol that increases concentration by 5 ppm in 5 min steps to a maximum of 25 ppm. We will measure the number of patients who meet an absolute safety endpoint during titration. An absolute safety endpoint requires execution of a rapid weaning protocol (2 ppm decrease per minute to 0 ppm). Absolute safety endpoints: Two consecutive SBP measurements more than one min apart with both readings < 80 mm Hg;SaO 2 <80% for more than 15 seconds; Patient deterioration as defined by: Clinical decision for need of inotropic or pressor support for any reason, seizure, new altered mental status, focal neurological signs suggestive of cerebral ischemia, evidence of myocardial ischemia, protracted vomiting. Test if the patient-reported Borg score decreases with administration of NO. Patients will not be told any details about the timing of the titration and will not be made aware of their iNO concentration when the Borg score is assessed.

This pilot study is mainly aimed to evaluate the feasibility and safety of the percutaneous Angiojet Rheolytic Thrombectomy (ART) in patients presenting a MPE. Secondarily the effectiveness of this treatment modality will also be estimated.

This study was designed to assess the safety of retrieval of the Bard Recovery® G2® Filter System. The G2 filter is an FDA-cleared device for inferior vena caval interruption in patients with pulmonary thromboembolism.

Oral anticoagulation is often initiated in hospitalized patients. Although the therapeutic range of phenprocoumon is narrow, the individual drug demands unfortunately vary greatly between persons. Our group recently developed two dosing algorithms for the initiation of anticoagulation based on clinical predictors such as age, gender, body weight and laboratory values. The aim of the proposed study is to prospectively evaluate the efficacy and safety of these two algorithms in medical and orthopedic inpatients, as well as in a group of outpatients and possibly in a geriatric collective.

The purpose of the study is to see if there is a difference in the amount of fat droplets reaching the heart during surgery between the standard reamer currently used and a new reamer system which is expected to reduce the fat going into the blood, via an intraoperative echocardiography done through the food pipe.

The primary objectives of the Multi MERCI trial were: to evaluate the addition of the Merci L5 Retriever additionally permit use of the Merci Retrieval System in the setting of persistent clot following IV t-PA treatment (use in the 0-8 hour window for patients ineligible for IV t-PA was also permitted)

Objectives are to evaluate whether idrabiotaparinux sodium (SSR126517E) is as least as effective as a standard warfarin treatment to prevent recurrence of venous thromboembolic events (VTE) in patients with symptomatic pulmonary embolism (PE) with or without symptomatic deep venous thrombosis (DVT) and to assess its safety (bleedings) versus warfarin.

Venous thromboembolism affects around 10 million people per year worldwide, however, despite its high incidence, there is no systematic review or randomized trial focused on the treatment of patients with recurrent deep vein thrombosis (DVT) and/or or pulmonary embolism (PE) during anticoagulant treatment. The objective was to compare the use of Rivaroxaban plus Aspirin versus Acenocoumarol in patients with recurrent venous thromboembolism treated with rivaroxaban.

This is a study in patients who recently had a brain attack (stroke) and in whom no clear cause of the stroke could be identified. These strokes are likely due to a blood clot and therefore, can be called embolic stroke of undetermined source. The abbreviation is ESUS. The study will compare 2 blood thinners. Patients will be randomly assigned to either Rivaroxaban 15 mg or Aspirin 100 mg and the study is intended to show, if patients given rivaroxaban have fewer blood clots in the brain (stroke) or in other blood vessels.
