Value of Prothrombin Fragment F1+2 in the Diagnosis of Pulmonary Embolism in Patients With Chronic...

Chronic Obstructive Pulmonary DiseasePulmonary Embolism

To access the clinical usefulness of F1+2 in the diagnosis of PE in patients with AECOPD who require hospitalization. Specifically, to determine whether F1+2 may have an additional value in the subgroup of patients with an abnormal D-dimer,to determine whether it may increase the proportion of patients in whom PE can be safely ruled out and to determine the sensitivity, specificity and NPV of F1+2 at various cut-off values.

Venous Thromboembolism (VTE)Deep Vein Thrombosis (DVT)1 more

Venous thromboembolism (VTE) with its two clinical manifestations deep vein thrombosis (DVT) and pulmonary embolism (PE) is a life-threatening disease that is associated with considerable morbidity and mortality. The incidence of VTE increases with age and it - as the third most common cardiovascular disease after ischemic heart disease and stroke - represents an important public health problem in industrialized countries with several aspects in need to be addressed. VTEval Project includes three long-term prospective observational studies to evaluate and improve VTE diagnostics and management, treatment and outcome. The aims of the project include a systematic assessment of VTE, i.e. disease status (symptoms, clinical and subclinical aspects) and risk profiles (classic, psychosocial and environmental factors), using a system-oriented approach. VTEval collects three large prospective cohorts of patients with suspected and incident VTE consisting of individuals with a clinical suspicion of acute PE, individuals with a clinical suspicion of acute DVT, and individuals with incidental diagnosis of VTE). The standardized and harmonized data acquisition of the study establishes a sustainable resource for comprehensive research on VTE, thus providing the basis for both short- and long-term analysis.

Lung Perfusion Measured With Dual-Energy CT in Patients With Chronic Thromboembolic Pulmonary Hypertension:...

Multidetector Computed TomographyPulmonary Embolism and Thrombosis1 more

A comparative, observational, cross-sectional and prolective diagnostic test study, including patients that have had a right heart catheterization and were referred for a CT pulmonary angiography as part of their imaging workup protocol for pulmonary hypertension. Dual-energy computed tomography (DECT) pulmonary angiography was performed on each patient to obtain perfusion maps and do a quantitative analysis. Segments with and without perfusion defects according to significant differences in the quantitative values, were defined as compatible or not with chronic thromboembolism. To assess the accuracy of the method and evaluate its performance, these results were compared with the sole results from the right heart catheterization, known to be the gold standard diagnostic tool.

Deep Venous ThrombosesPulmonary Embolism1 more

The purpose of this study is to demonstrate the ability of new D-Dimer assay combined with a clinical pretest probability (PTP) to safely exclude pulmonary embolism (PE) or Deep Venous Thrombosis (DVT) in a 3 month follow-up.

Thrombus Elastography in Venous Thrombo-Embolism.

Venous Thromboembolism

Venous Thrombo-Embolic Disease (VTED) is a serious and common ailment, defined by the growth of a clot - or thrombus - in a vein, and/or as the migration of this thrombus to a pulmonary artery. It represents the third cause of death after cardio-vascular disease and cancer, and encompass superficial, muscular and Deep Venous Thrombosis (DVT), and Pulmonary Embolisms (PE), which can be isolated or associated. Ultrasound is today the most frequently used exam to diagnose DVT. However, it's unable to provide information on thrombus age or cause. Elastography is an imaging technic which aims to analyse elastic properties of a tissue, by applying a mechanical impulse on it, and could be an interesting tool in thrombus exploration, and provide additional information.

Thrombembolism After Robot- Assisted Surgery in Urology

Urologic CancerThrombosis2 more

Cancer patients have an increased risk of perioperative complications undergoing surgery procedures. Postoperative complications caused by thrombembolic events after robot- assisted surgery in major urological procedures have been reported and associated with an increased lenght of stay in the hospital. We therefore aimed to investigate in a retrospective analysis 250 patients undergoing robotic-assisted radical cystectomy and prostatectomy procedures for risk factors for thrombembolic events in this specific patient population.

CTEPH in Patients With Prior Pulmonary Embolism and Risk Score Validation

Chronic Thromboembolic Pulmonary HypertensionPulmonary Embolism

CTEPH-SOLUTION aims to create a risk score for the early detection of Chronic Thrombo-Embolic Pulmonary Hypertension (CTEPH) among patients with previous pulmonary embolism. The risk score, created on retrospective data, will be validated on newly diagnosed pulmonary embolism patients.
