Filter by:The purpose of this study is to determine if the risk of recurrent venous thromboembolism (VTE) after stopping therapy is low and acceptable in patients with a first unprovoked proximal deep vein thrombosis (DVT) or pulmonary embolism (PE) who have completed 3 months of therapy and who have a negative D-dimer test on therapy and 1 month after stopping therapy.
Background: Compare the American and Brazilian protocols for prophylaxis of deep vein thrombosis (DVT), seeking to draft a new protocol, more comprehensive and applicable. Methods: A prospective study was conducted over a year, covering 212 patients, comparing the protocols on the stratification of risk of DVT, and the type of prophylaxis indicated. A new protocol was proposed, applied and compared to previous.
The purpose of this study is to evaluate whether low-molecular-weight heparin could be equally or more effective than oral anticoagulation in the long-term treatment of deep venous thrombosis.
The Kids-DOTT trial is a randomized controlled clinical trial whose primary objective is to evaluate non-inferiority of shortened-duration (6 weeks) versus conventional-duration (3 months) anticoagulation in children with first-episode acute venous thrombosis. The first stage of the trial has consisted of a pilot/feasibility component, which then continues as the definitively-powered trial.
Cancer is a well known risk factor for venous thromboembolism (VTE) such as deep venous thrombosis (DVT) and pulmonary embolism (PE). Today we know that patients with adenocarcinomas of the gastro intestinal tract (GI-tract) often is in a hypercoagulable state. In our observational study we collect patients admitted to department with a tentative diagnosis of upper GI cancer including pancreas cancer and offer them flow doppler ultrasounds of both legs for diagnosis of DVT in the entire treatment time. The routine CT-scan of the chest is modified to diagnose PE. This will be compared with blood samples analysed for coagulation markers including D-dimer - a fibrinogen degradation product.
The purpose of this study is to evaluate the effects of an investigational blood thinner, apixaban, in preventing venous thromboembolic (VTE) recurrence or death in patients with deep vein thrombosis (DVT) or pulmonary embolism (PE)
The purpose is to evaluate the effects of an investigational blood thinner, apixaban, in preventing venous thromboembolic (VTE) recurrence or death in patients who have completed their intended treatment for deep vein thrombosis (DVT) or pulmonary embolism (PE)
The purpose of the study was to evaluate efficacy and safety of the new acute treatment of deep venous thrombosis by use of low-molecular-weight heparin compared with standard treatment using unfractionated heparin, especially concerning long-term morbidity.
Background. The optimal duration of oral anticoagulant treatment in patients with idiopathic Deep Vein Thrombosis (DVT)of the lower limbs is still uncertain. Residual Vein Thrombosis (RVT) has been found able to establish the patient' risk for recurrent thrombotic events. In the present study we conducted a RVT-based therapeutic strategy, withholding OAT after 3 months in patients without RVT while continuing anticoagulants for at least additional 9 months in those in whom RVT persists. Methods Patients with a first episode of symptomatic unprovoked proximal Vein Thrombosis (VT) were given Oral Anticoagulant Treatment (OAT) for 3 months. Residual Vein Thrombosis (RVT), ultrasonographically-detected, will be then assessed. Patients without RVT did not continue OAT (Group B), whereas those with RVT will continue OAT for at least additional 9 months. Patients were followed-up prospectively focusing on the study outcomes: occurrence of recurrent venous thromboembolism and major bleeding over a period of at least 12 months after OAT discontinuation.
We are performing a research study to learn more about the control of an individual's blood thinning (anticoagulation) on warfarin. Individuals from an anticoagulation clinic are being asked to participate in order to see if a lottery which provides the opportunity to win money in combination with the use of the Med-eMonitor might be useful in helping patients to achieve better control of their anticoagulation therapy. Half of the participants will be enrolled in the lottery arm and the other half will be a control group who will receive the Med-eMonitor only.
