Active clinical trials for "Venous Thrombosis"

Evaluation of physician responses to BICS-Clinical Information 3-screen alerts that informs the clinician that his/her patient may be eligible for thromboprophylaxis.

This study aims to analyze the post-operative functional training on the prevention of deep venous thrombosis (DVT) in the patients who have accepted major surgeries for the gynecological malignancies. The functional training consists of: (1) active and passive ankle pump motions including flexion and extension, circumduction; (2) abdominal breathing training. The primary end is the incidence of DVT happened 30 days from surgery. The secondary ends include the patients satisfaction about functional training.

This study evaluates the impact of community pharmacists' educational training on the nature and adequacy of counseling provided to patients on warfarin, an oral anticoagulant. Half of the community pharmacists participating in the study will receive a two-week educational training on how to adequately counsel patients on warfarin while the other half of community pharmacists will receive the same training after the study. A mystery patient model will be used in this intervention study where six different trained and standardized individuals will act as patients. Each of these mystery patients will supposedly have pulmonary embolism, deep vein thrombosis, or atrial fibrillation. The mystery patient will visit each pharmacy to buy warfarin or complain about adverse drug reaction been experienced. It is expected that pharmacists will provide relevant information and counseling to these patients on the use of the medication warfarin and how to handle the adverse drug reactions.

The ULTREC research project is designed to assess the safety of a negative strategy relying on Colour Doppler Ultrasound (CDUS) for excluding the diagnosis of a new thrombosis. The ULTREC project does not take into account the validity of the CDUS positive criteria used to confirm the diagnosis of Deep Vein Thrombosis (DVT) recurrence. The risk of considering only the negative strategy is to ignore the possibility of having an improvement in sensitivity and negative predictive value at the expense of specificity and positive predictive value and therefore to increase the false positive rate leading to an overdiagnosis of recurrence and an overtreatment, and a potential bleeding risk. In the ULTREC-ANCILLARY study, the research will aim at assessing the validity of baseline CDUS positive criteria for the diagnosis of DVT recurrence. As there is no diagnostic standard to which the results could be compared, it is suggested to validate these criteria based on the evolution of the thrombosis on CDUS performed at D90±5. The hypothesis is that an unchanged appearance under anticoagulation would be in favor of sequelae and will invalidate the initial diagnosis (diagnostic failure)

In this study a retrospective analysis of patients database was performed, who underwent treatment for deep vein thrombosis in tertiary hospital by using inferior vena cava-filters

The purpose of this study is to determine the effectiveness of infrared thermal imaging in adjunctive diagnostic screening for lower limb deep venous thrombosis (DVT).

The purpose of this study is to assess if accumulation of anti-Xa activity occurs after repeated daily administration of prophylactic doses of tinzaparin in patients with severe chronic kidney disease (CKD) requiring thromboprophylaxis for non-surgical conditions. It is anticipated that tinzaparin used at a fixed dose for thromboprophylaxis in severe CKD patients (eGFR ≤ 30 ml/min /1.73 m2) at risk for venous thromboembolism (VTE) will not bioaccumulate at a significant level, meaning an increase of ≥ 20% of the anti-Xa mean level between day 2 or 3 and day 5.

The issue to be studied is the prevalence of venous thromboembolism (VTE) in hospitalized pediatric patients, and to identify if there are subgroups of patients who may be at higher risk. There are two hypotheses that will be looked at in this study. The first hypothesis is that individual risk factors for VTE in hospitalized pediatric patients are: age >14, obesity, black race, female sex, presence of a central venous line (CVL), traumatic mechanism of injury, orthopaedic surgery, and use of oral contraceptives. The second hypothesis is that risk factors have an additive effect such that risk stratification can be developed to identify those patients with the highest risk.

The objective of the EDVIGE study is to determine whether a negative single distal and proximal leg veins compression ultrasonography safely rules out the diagnosis of deep vein thrombosis in pregnant and post-partum women with clinical suspicion of DVT.

Deep vein thrombosis (DVT)is devastating disease which influencing the mortality and morbidity of patients at-risk like those undergoing orthopedic surgery. Recent publication suggested HMO-co-A reductase inhibitor (statin) may reduce the occurrence rate of venous thromboembolism in apparently healthy persons. The pleiotropic property of statin like antioxidant, antithrombotic, anti-inflammatory may have effect on the positive results. We are investigating whether rosuvastatin is associated with lower incidence of deep vein thrombosis (DVT) in patients undergoing total knee replacement arthroplasty(TKRA)who are at-high risk for developing DVT
