Filter by:The purpose of this study is to document the long-term outcome or prognosis of patients diagnosed with upper extremity deep-vein thrombosis who are treated with Fragmin (dalteparin sodium injection) for three months.
Odiparcil is being studied to determine if it can prevent blood clots from forming after a total knee replacement and also to prove that odiparcil is safe.
The purpose of this study is to assess the effect of the anticoagulant(blood thinner) Clexane on the development of leg clots following electrophysiology studies (EPS) and or radiofrequency ablation (RFA). People who suffer heart palpitations will sometimes need hospital admission to undergo an electrophysiology study ( and or a Radiofrequency Ablation)in order to diagnose and or treat their condition. Radiofrequency ablation is a procedure to stop abnormal heart rhythms. EPS/RFA studies require the puncture of the leg veins . Previous experience has shown that following the puncture of leg veins there is a small risk of developing a blood clot in the leg. It is not known whether giving blood thinners (anticoagulants) after the procedure will decrease this risk Enoxaparin Sodium (Clexane) is an anticoagulant used extensively and safely following bone (Orthopaedic) surgery to prevent blood clots from developing in the legs
Venous thromboembolism (VTE) remains the most common cause of maternal death in the developed world. VTE includes two conditions, deep vein thrombosis (DVT) and pulmonary embolism (PE). DVT refers to a blood clot that has formed in a deep vein, often in the legs and/or pelvis and PE refers to the passage of these clots into the lungs (which can be fatal). VTE is up to 10 times more common in pregnant women than non-pregnant women of comparable age. More than a third of pregnancy related VTE occur during the 6 weeks after delivery. When compared with vaginal delivery, cesarean delivery further increases the risk of pregnancy associated VTE by three-fold. A medication called low molecular weight heparin is sometimes prescribed during pregnancy and after delivery to prevent VTE. However, clinical practice varies because there hasn't been adequate research to determine that this medication is safe and effective at preventing VTE during this time. The potential benefits of the medication must also be weighed against its cost and possible side effects. The researchers are conducting a study that will assess the effectiveness and safety of low molecular weight heparin in women who are at moderate to high risk of VTE after a cesarean section. They will monitor these women to determine if those who received the medication have fewer blood clots. Participants will also be monitored closely for any side effects.
It is known that patients who fracture their legs sometimes develop blood clots (known as deep vein thrombosis) in their legs. These clots may cause pain and swelling in the leg or they may detach and travel to the lungs producing shortness of breath, chest pain, and sometimes death. Unfortunately, it is not known how frequently these complications occur after leg fractures, or if the use of a blood thinner medication can effectively and safely prevent these clots. Doctors at hospitals across Canada are conducting a study in which patients who have surgery for leg fractures receive either a once-daily injection of a blood thinner, known as low molecular weight heparin, or a placebo injection for up to 14 days after their fractures. Neither the patients nor the doctors know which patient is on the medication and which patient is on placebo. All patients receive an ultrasound examination of their legs at 2 weeks after surgery to monitor for deep vein thrombosis. In addition, all patients are checked for symptoms of leg or lung clots and any side effects of the medication for 3 months. If the blood thinner is shown to be effective at reducing this complication and documented to be safe and cost-effective in this setting it will be recommended for use in such patients. If, on the other hand, the frequency of deep vein thrombosis is too low to justify the cost or inconvenience of taking this medication, this will also be an important finding.
FIDO was a multicentred randomized, open-label trial that compared fixed-dose UFH with fixed-dose LMWH for initial treatment of VTE. Patients were followed for 3 months during which they received warfarin (target INR 2.0-3.0).
To determine whether d-dimer testing can be used to simplify and reduce the costs of the diagnostic approach to patients with clinically suspected deep vein thrombosis
To simplify and improve the diagnostic approach to patients with clinically suspected recurrent DVT by determining whether the results of the combination of IPG and d-dimer testing, using a whole blood agglutination assay, can be used in the management of such patients.
The purpose of this study is to compare two diagnostic interventions to improve the way D-dimer blood testing (MDA D-dimer) is used to diagnose first time symptomatic deep vein thrombosis.
To determine whether treatment and further investigation can be safely withheld in patients who present with suspected recurrent deep vein thrombosis (DVT) and have either a (i) negative D-Dimer or (ii) a positive D-Dimer with normal serial compression ultrasound.
