Filter by: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)
This is a prospective, multi-center single arm registry to assess the use of the OmniWave Endovascular System in subjects presenting with either lower or upper extremity acute (symptoms have been present for greater than or equal to 14 days) DVT.
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 primary hypothesis of this study is that occult catheter-related DVT in children with cancer is common and directly contributes to development of serious catheter complications, specifically bacteremia/fungemia and/or recurrent occlusion of the catheter tip. Accordingly, anticoagulant treatment of clinically silent (occult) DVT will reduce rates of catheter-related infection and occlusion, delays in therapy and need for catheter replacement.
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.
The aim of this study was to compare the safety and efficacy of warfarin versus placebo, administered for 6 months, in the prevention of thromboembolic complications after transvenous cardiac devices implantation in high-risk patients.
Several case reports indicate that the use of the antibiotic combination amoxicillin and clavulanic acid (AM-CLAVAC) can interact with warfarin pharmacodynamics. However, fever per se might also be responsible of these warfarin overdose reports, as well as the use of high dose paracetamol. The aim of the present study is to determine if AM-CLAVAC can increase the pharmacodynamics of warfarin among patients at steady state Double blinded cross over controlled study vs placebo performed in 12 evaluable patients treated with warfarin with an INR target 2 to 3 and a stable INR and a stable dose.
In the literature, cases of thrombosis in the venous system have been described in girls and women with Turner syndrome. By screening a group of women with Turner syndrome, the researchers wish to find out if this condition is more frequent in this patient population.
