Filter by:Anticoagulant therapy is generally recommended for all patients presenting with acute symptomatic splanchnic vein thrombosis, starting with either low-molecular weight heparin (LMWH) or unfractionated heparin and continuing with the vitamin K antagonists in most patients. Rivaroxaban is approved for the treatment of deep vein thrombosis and pulmonary embolism, but no studies have assessed the safety of rivaroxaban in the setting of splanchnic vein thrombosis. The investigators aim to collect prospective information on the safety of rivaroxaban in a pilot cohort of 100 patients with acute splanchnic vein thrombosis without liver cirrhosis.
Observational. Retrospective cohort.
This is prospective cohort study in pregnant women who present with signs and symptoms of possible deep vein thrombosis (DVT). All patients will have the same method of assessment of their DVT symptoms (the LEFt clinical decision rule will be applied and D-dimer test will be done) to determine if a compression ultrasound is required. All patients will be followed for a period of 3 months.
portal vein thrombosis may be a negative prognostic marker of variceal bleeding in liver cirrhosis. Compared with conventional endoscopic and pharmacological therapy, transjugular intrahepatic portosystemic shunt may further improve the outcomes of portal vein thrombosis in liver cirrhosis with variceal bleeding.
To determine the effect and safety of anticoagulation after endoscopic therapy in cirrhotic patients with portal vein thrombosis and to explore whether it can decrease the short-term rebleeding rate.
Prospective validation of an age-adjusted D-dimer cut-off to rule out deep vein thrombosis (DVT)
The purpose of the study is to prove equivalence of efficacy and safety of BCD-080 and Clexan for deep vein thrombosis and embolism prophylaxis at orthopedic surgeries.
This study is to further develop and optimise the design and manufacturing process of a handheld device to monitor and manage Warfarin (blood thinning anticoagulation drug) therapy. The device comprises of a handheld instrument and a disposable test strip and reports how blood coagulation is working in terms of standardised units called International Normalised Ratio (INR). A single drop of fresh whole blood and plasma will be added to the strip and the INR result displayed on the instrument. Blood samples are to be collected from patients attending a hospital based INR clinic who are on Warfarin Therapy. The samples are to be used in a series of experiments in the laboratory to test the Microvisk POC INR Monitors accuracy, precision, stability and robustness.
The use of neuromuscular electrical stimulation (NMES) as a home-based therapy following total knee arthroplasty. Measures of interest: lower limb venous hemodynamics, joint range of motion, lower limb swelling, walking speed, quality of life, activities of daily living, device usability, device compliance, activity levels, and pain (VAS).
The risk of developing a blood clot occurs in up to 60% of all critical care patients. Many times enoxaparin (or Lovenox) is given to patients who are at a higher risk of developing clots in their legs or lungs. There are two standard doses of enoxaparin that are recommended by the drug companies. These two doses have never been directly compared in trauma, general, and vascular surgery patients. The purposes of this study are: 1. to compare the development of blood clots in patients receiving 30mg twice daily of enoxaparin compared to patients receiving 40mg once daily of enoxaparin. 2. to determine if there is higher risk of bleeding complications in patients receiving 30mg twice daily of enoxaparin compared to patients receiving 40mg once daily. Patients enrolled into the study will be randomized to receive enoxaparin, 30mg twice daily or enoxaparin, 40mg once daily. Patients will then be monitored for signs and symptoms of blood clots. At the time of discharge (or before, if medically indicated), an ultrasound test will be performed to look for blood clots in the patient's legs. The investigators will compare incidence of blood clots formed between the 2 groups of patients to determine if one dose of enoxaparin relates to a lower rate of blood clots in critically ill patients. The investigators will also compare the incidence of bleeding complications between the 2 groups.
