title: Detection of anticoagulation therapy failures in patients with venous thrombosis.
abstract: Results of ultrasonic monitoring of venous patency and fibrinogen uptake testing were evaluated in ten patients with venous thrombosis receiving heparin therapy. Two propagating venous thromboses were detected 24 to 48 hours before massive pulmonary embolism developed, thus emphasizing the usefulness of these methods for detection of anticoagulation therapy failures.
