Active clinical trials for "Thromboembolism"

This research study is a prospective randomized trial evaluating the relative safety of two inferior vena cava (IVC) filters used to prevent the migration of potentially dangerous deadly blood clots from the legs to the lung in patients who cannot take blood thinners. All eligible patients will have been ordered to have a IVC filter placed by their primary medical team and filters will be placed in these patients whether or not they wish to participate in this trial as part of standard of care. The investigators will follow up with patients 30 days after IVC filter placement and ask them to come back for filter removal if medically appropriate. If removal is not medically appropriate in 30 days, the investigators will attempt to schedule removal every 30 days after initial placement. Primary outcome measures will be IVC filter complications such as filter penetration through the IVC wall and into other organs, filter tilt, filter migration, filter fracture and clots formed within the filter. All of these are reported complications of all IVC filters. The research also aims to improve the standard of care for IVC filter patient follow up as the FDA and Society of Interventional Radiology recommend that IVC filters be removed as soon as it is safe to do so. Hypothesis: The investigators hypothesize that there is no significant difference in efficacy and complication rate between the Option and the Denali filter.

Primary objective: To determine whether aspirin (ASA) can lower the incidence of Venous Thromboembolism(VTE) in patients with Glioblastoma (GBM). Secondary objectives: To determine clinical and laboratory factors which are associated with increased risk of VTE If it is determined that ASA reduces the incidence of VTE in patients with GBM, then to determine the clinical and laboratory factors which are associated with an increased benefit from the drug.

The development of clots is a potentially deadly complication in many cancer patients. The current optimal treatment is unknown. Evidence supporting the effectiveness of the use of Inferior Vena Caval Filters is lacking. This study will compare the two standard of care treatment options: anticoagulation with or without a inferior vena cava filter. The anticoagulation medication chosen will be Arixtra and it will be given once a day as an injection. Patients will be called at various intervals to monitor their signs and symptoms of new thromboembolisms.

Due to increasing of life expectancy, patients with von Willebrand disease are exposed to age-related pathologies such as cancer or cardiovascular diseases. Management of thrombotic events is challenging given the inherent bleeding risk in von Willebrand disease. Few data are currently available in the literature. The aim of the study is to describe the frequency and nature of arterial and venous thromboembolic events and atrial fibrillation in patients with von Willebrand disease in the West of France. The investigators will perform a retrospective multicenter study conducted in the von Willebrand population of the French West. Von Willebrand adult patients followed in one of the French West medical centers participating in the study, who presented deep vein thrombosis, pulmonary embolism, ischemic stroke, transient ischemic attack, acute coronary syndrome, acute limb ischemia, atrial fibrillation, arteriopathy of the lower limbs, angina will be eligible.

In individuals with obesity, the optimal dosing and duration of venous thromboembolism (VTE) prophylaxis in settings representing acute medical illness or surgery is limited due to lack of randomized controlled trials (RCTs) focusing specifically on this population. Evidence suggests that in obese participants, both higher dosing and duration of VTE prophylaxis with Low Molecular Weight Heparins (LMWH) may be required to achieve a therapeutic effect similar to non-obese participants. This non-interventional study utilizes data already collected from a usual clinical practice setting in the Optum US clinical database, representing obese participants hospitalized with an acute medical condition or undergoing surgery receiving enoxaparin prophylaxis. Its aim is to compare the impact of the following enoxaparin prophylaxis strategies on the incidence of symptomatic VTE and major bleeding in the overall study population and prespecified subgroups: High versus conventional dose Extended versus conventional duration Combined High-Dose and Extended-Duration versus Conventional-Dose and Conventional-Duration. The first date of enoxaparin prophylaxis will be the index date.

The LIFE study (Lung cancer, Immunotherapy, Frailty, Effect) is investigating the unselected 'real life' non-small cell lung cancer (NSCLC) population treated with immune checkpoint inhibition.

Interventional, no-randomized, open-label, and single arm multicentre study of apixaban for the prevention of thromboembolic events during induction therapy in transplant-eligible patients with newly diagnosed multiple myeloma who receive bortezomib, thalidomide, and dexamethasone (VTD) during the induction phase of therapy prior to autologous stem cell transplantation (ASCT). The current study is designed to evaluate the efficacy and safety of apixaban during the induction period. Efficacy will be defined as a composite endpoint of acute symptomatic proximal and distal deep venous thrombosis, pulmonary embolism, VTE related deaths, and acute ischemic stroke.

The purpose of this study is to show feasibility (efficacy and safety) of Rivaroxaban in the treatment of VTE in cancer patients in comparison to the standard treatment with low molecular weight heparin (LMWH). Tumor patients with active cancer and newly diagnosed thromboembolic events are randomised to receive either Rivaroxaban or the standard treatment with low-molecular heparin.

In an open-label parallel groups blinded-endpoint randomized clinical trial, the investigators aim to assess the safety and efficacy of conventional catheter-directed thrombolysis (CDT) vs anticoagulation monotherapy on outcomes of patients with acute intermediate-high risk pulmonary embolism. The investigators hypothesize that CDT will have a superior efficacy and safety compared with anticoagulation-only therapy regarding the proportion of patients with a right ventricle to left ventricle (RV/LV) ratio > 0.9 at a 3-month follow-up by an imaging core laboratory, major bleeding, severe thrombocytopenia, or vascular access complication.

Introduction: Venous thrombosis (VTE), including both deep vein thrombosis (DVT) and pulmonary embolism (PE) remains a frequent complication in patients admitted to the Intensive Care Unit (ICU). Multiple prediction models for estimating the risk of VTE have been developed. However, many models have not been externally validated. The aim of this study is to perform a comprehensive external validation of pre-existing prediction models for predicting the risk of in-hospital VTE in critically ill patients. In case current risk assessment models fail, the investigators aim to additionally develop and internally validate a new risk prediction model. Methods: During the first phase of the study the investigators will perform external validation of existing prediction models. The performance, discrimination, calibration and clinical usefulness of the models will be evaluated. In the second phase of the study, in case performance of current risk assessment models is deemed insufficient for clinical application, the investigators will develop a model for predicting the risk of in-hospital VTE in critically ill patients. A multivariable prediction model will be constructed using a combination of predefined candidate predictors. This model will be internally validated and performance will be compared with performance of existing VTE risk prediction models. Dissemination: This protocol will be published online. This study will be reported according to the Transparent reporting of a multivariable prediction model for individual prognosis or diagnosis (TRIPOD) statement and this study will be submitted to a peer-reviewed journal for publication.
