Risk Stratification for Venous Thromboembolism in Hospitalized Medical Patients
Venous ThromboembolismVenous Thromboses5 moreHospital-acquired venous thromboembolism (HA-VTE) is one of the leading preventable causes of in-hospital mortality, but prevention of VTE in hospitalized medical patients remains challenging, as preventive measures such as pharmacological thromboprophylaxis (TPX) need to be tailored to individual thrombotic risk. The broad objective of this project is to improve VTE prevention strategies in hospitalized medical patients by prospectively examining VTE risk factors (including mobility) and comparing existing risk assessment models.
Prevalence of Pulmonary Embolism in Patients With Dyspnea on Exertion (PEDIS)
Pulmonary EmbolismPEDIS Study is an observational, cross-sectional, multicenter Italian study conducted in a consecutive series of patients who refer to the Emergency Departments (either spontaneously or sent by their attending physicians) for the recent (less than one months) development of exertional dyspnea. The general aim of the study is to assess the prevalence of PE in the overall population referring to the Emergency Departments without potential explanations for dyspnea
The Incidence of Pulmonary Embolism During Nephrectomy
Pulmonary EmbolismRenal Cell Carcinoma1 morePatients with renal carcinoma was reported at high incidence of perioperative pulmonary embolism from current study. The investigators aimed to determine the incidence and outcome of this group of patient in the tertiary-care, university hospital and the rate of intraoperative transesophageal echocardiography utility and outcome.
Pulmonary Embolism: an Autopsy Study
Pulmonary EmbolismBACKGROUND: Pulmonary embolism (PE) is associated to high mortality rate worldwide. However, the diagnosis of PE often results inaccurate. Many cases of PE are incorrectly diagnosed or missed and they are often associated to sudden unexpected death (SUD). In forensic practice, it is important to establish the time of thrombus formation in order to determine the precise moment of death. The autopsy remains the gold standard method for the identification of death cause allowing the determination of discrepancies between clinical and autopsy diagnoses. The aim of our study will be to verify the morphological and histological criteria of fatal cases of PE and evaluate the dating of thrombus formation considering 5 ranges of time. METHODS: Pulmonary vessels sections will be collected from January 2010 to December 2017. Sections of thrombus sampling will be stained with hematoxylin and eosin. The content of infiltrated cells, fibroblasts and collagen fibers will be scored using a semi-quantitative three-point scale of range values. Hypothesis: After a macroscopic observation and a good sampling traditional histology, it will be important to identify the time of thrombus formation. We will identify histologically a range of time in the physiopathology of the thrombus (early, recent, recent-medium, medium, old), allowing to determine the dating of thrombus formation and the exact time of death.
Incidence of Pulmonary and Venous Thromboembolism in IVF Pregnancies After Fresh and Frozen Embryo...
Assisted Reproductive TechniquesPregnancy4 moreIn vitro fertilization (IVF) is associated with an increased risk of venous thromboembolism and in particular pulmonary embolism during the first trimester. It is not known whether this increased risk of pulmonary embolism is present both after fresh and frozen embryo transfer. Objective: To assess whether the risk of pulmonary embolism and venous thromboembolism during the first trimester of IVF pregnancies is associated with both fresh and frozen embryo transfer. A population-based cohort study with linked data from nationwide registries on women in Sweden giving birth to their first child 1992-2012
Symptom-driven Referral for Evaluation of Chronic Thromboembolic Disease or Pulmonary Hypertension...
Chronic Thromboembolic Pulmonary DiseaseAim: To investigate if a symptom driven referral for chronic thrombosis in the lungs after acute pulmonary embolism is better than the current approach. Background: A number of patients with chronic thrombosis in the lungs after acute pulmonary embolism have dyspnea and reduced functional capacity without elevated pulmonary arterial pressure at rest (CTED). However, current guidelines for follow-up after acute pulmonary embolism will miss all patients with CTED, as referral for further examination is based on elevated pulmonary arterial pressure on echocardiography. Thus, the prevalence of CTED is unknown. The hypothesis is, that a symptom-driven referral of patients with previous acute pulmonary embolism is more sensitive in diagnosing CTED than the current approach. Methods and materials: Patients diagnosed with acute pulmonary embolism in Region Midt (approx. 350 per year) will be screened for non-recovery or persistent pulmonary embolism related symptoms during their 3-6 months follow up at their local outpatient clinic. If the patient has persistent symptoms they will be referred to a scintigraphy. If CTED is suspected from the scintigraphy, the patient will be referred for full CTED work-up. The investigators expect to screen 300 patients for persistent symptoms with an expected study time of 3 years.
The Risk of Venous Thromboembolism in Systemic Inflammatory Disorders: a United Kingdom (UK) Matched...
Venous ThrombosesVenous Thromboembolism7 moreBlood clots occurring in the legs and in the lungs are relatively common; they occur in around 3 in a 1000 people per year. They can cause disability and are also potentially life threatening. When a clot occurs in the legs it is called a deep vein thrombosis or DVT. When they occur in the lungs they are called a pulmonary embolism or PE. The risk for DVT and PE is higher in people with conditions which cause inflammation. The most common of these are inflammatory bowel disease (ulcerative colitis and Crohn's disease), rheumatoid arthritis, and psoriatic arthritis (a condition comprised of psoriasis and joint inflammation). What is not known is how much higher the risk of DVT and PE is in these groups compared with people without inflammatory disease, and what causes the excess risk in these people. This study aims to assess the measure the exact increase in risk for DVT and PE in people with these inflammatory conditions and to identify which risk factors are most strongly associated with the increased risk. These data should help with an understand the causes of blood clot risk in these inflammatory conditions and in identify targets for reducing risk.

Assessment of Contrast Enhancement Boost for the Direct Identification of Pulmonary Emboli in Thoracic...
Pulmonary EmbolismPulmonary embolism is a common cardiovascular disease and thoracic CT angiography is currently considered the gold standard for its non-invasive diagnosis. However, the diagnostic performance of CT angiography can be hampered by an insufficient enhancement of pulmonary arteries. Contrast Enhancement Boost (CE Boost) is a post-processing technique using an iodine density map to artificially improve pulmonary artery enhancement. This retrospective study compares standard CT-angiography images with CE Boost images to assess the potential improvement of diagnostic performance for the detection of pulmonary embolism.
