BACKGROUND Enoxaparin sodium, a low-molecular-weight heparin, was recently approved for use in the United States to prevent deep-vein thrombosis after total hip replacement surgery. Its cost-effectiveness relative to prophylaxis with low-dose warfarin sodium is unknown. METHODS A decision-analytic model was developed to compare two strategies of prophylaxis for deep-vein thrombosis with a str...

Deep vein thrombosis and pulmonary embolism are major health problems associated with high mortality. Recently, DNA-based neutrophil extracellular traps (NETs) resulting from the release of decondensed chromatin, were found to be part of the thrombus scaffold and to promote coagulation. However, the significance of nuclear decondensation and NET generation in thrombosis is largely unknown. To a...

BACKGROUND The efficacy and safety of anticoagulant treatment for patients with acute, symptomatic superficial-vein thrombosis in the legs, but without concomitant deep-vein thrombosis or symptomatic pulmonary embolism at presentation, have not been established. METHODS In a randomized, double-blind trial, we assigned 3002 patients to receive either fondaparinux, administered subcutaneously a...

Plasminogen is a key proenzyme in the fibrinolytic and thrombolytic systems. Congenital deficiency of plasminogen and molecular abnormality of plasminogen (dysplasminogenemia) have been reported in association with the thrombotic tendency in human. In dysplasminogenemia, the level of immunoreactive plasminogen is normal, although the functional activity is reduced. Human plasminogen gene spans ...

Acute symptomatic deep vein thrombosis (DVT) is usually managed by intravenous heparin and oral warfarin. Recently, direct oral anticoagulants (DOAC) have been introduced for the treatment of acute DVT. DOAC may be useful for very elderly patients who live in rural areas, where medical resources are limited. An 83-year-old woman presented to our clinic with left leg edema. Contrast enhanced com...
