Filter by:This study is a prospective, single-arm, non-randomized, interventional, multicenter feasibility study to evaluate the safety and effectiveness of percutaneous mechanical thrombectomy using the Akura Thrombectomy System in subjects with acute pulmonary embolism (PE).
Objective: to evaluate the efficacy and safety of the non-immunogenic recombinant staphylokinase with its single bolus administration in comparison with placebo in normotensive patients with intermediate high-risk pulmonary embolism (PE)
1. Integrate pharmacokinetic-pharmacodynamic (PK-PD) modeling and pharmacogenomics techniques to develop a population PK-PD model, aiming to explore monitoring and dose guidance schemes for Direct Oral Anticoagulants (DOACs). 2. Investigate the factors influencing PK-PD of DOACs in the pulmonary embolism population, clarifying the correlation between genotype characteristics and clinical outcomes. 3. Explore the correlation between drug concentrations, coagulation indices, and clinical outcomes of DOACs, defining the indications for DOACs testing and the overall monitoring process.
Evaluation of ultra low dose protocols and Iomeron 400 contrast in PCD-CT
The goal of this observational study is to analyse the association between anti-factor Xa activity (antiXa) and the occurence of venous thromboembolism (VTE; either deep vein thrombosis and/or pulmonary embolism) in critically ill patients who are admitted to an intensive care unit. The main questions it aims to answer are: - What is the association between antiXa and VTE? - What is the association between antiXa and symptomatic, respectively incidental, VTE? - How is pharmacological anticoagulation with enoxaparin related to measured antiXa? - What is the association between antiXa and bleeding complications. - What is the incidence of venous thromboembolism in patients treated at an intensive care unit? - How is the occurence of VTE related to patient-centred outcomes such as mortality, quality of life, length of stay and days outside of the intensive care unit/hospital.
Multicenter longitudinal observational ambispective (retrospective cases from 2014 and prospective from 2018 onwards) cohort study. The registry recruits a series of consecutive patients admitted for moderate-high risk or high-risk pulmonary embolism (according to 2019 European Society of Cardiology guidelines) treated invasively. This study aims to describe the acute management of the safety and effectiveness of different percutaneous interventions for acute pulmonary embolism.
It is important to diagnose pulmonary embolism in a timely manner to prevent death and long-term disability. More than half a million people (4-5% of emergency department patients) are tested for pulmonary embolism, although positive results are low. Imaging for PE testing exposes patients to radiation, is expensive, adds time to the emergency visit, and can lead to a false positive diagnoses. Existing protocols aimed at reducing unnecessary pulmonary embolism imaging are complex and seldom used by emergency physicians. Too many patients undergo unnecessary pulmonary embolism imaging. We have created a new tool (called Adjust-Unlikely) which could safely reduce pulmonary embolism imaging in Canada. Our research group composed of researchers, emergency physicians, and patients developed the Adjust-Unlikely clinical decision rule: a rule which has been customized for emergency physicians and emergency patients. Adjust-Unlikely is highly sensitive at the bedside, meaning there are very few false negative results. Our study aim is to prospectively validate Adjust-Unlikely pulmonary embolism testing in emergency patients with suspected pulmonary embolism.
This study is a quality improvement project to evaluate health care management of pulmonary embolism (PE) patients. The researchers are testing an intervention to determine if it prevents unnecessary hospital admissions.
SONIC-PE is a multicenter, prospective, single-arm study of 10 patients with bilateral PE treated with ultrasound-facilitated, catheter-directed lower-dose fibrinolysis (total dose 8 mg tPA given as 2 mg/hour/catheter over 2 hours) followed by 50 patients (total dose 6 mg tPA given as 3 mg/hour/catheter given over 1 hour) with the EKOS+™ system to determine its impact on the change in RV-to-LV diameter, refined Modified Miller Score, and distal pulmonary vascular blood volume as well as to assess International Society on Thrombosis and Haemostasis (ISTH) major bleeding.
Calcified cerebral embolism (CCE) is a relatively rare but underdiagnosed cause of infarction. CCE diagnosis is made by CT. Radiological characteristics of CCE have been reported in small case series. The aim of this study was to describe clinical and radiological characteristics of CCE in a large number of patients, and to compare patients with different radiological CCE characteristics.
