Study Summary
To determine the rate of thromboembolic complications (including death attributed to thromboembolic disease) in patients with a score rated as "DVT likely" on a formalized scoring system, when anticoagulation therapy is withheld on the basis of a negative comprehensive duplex ultrasound examination. Participants are followed for three months after a normal ultrasound to determine if any symptoms attributable to deep vein thrombosis develop. Any such symptoms are verified by objective tests.
Primary Outcome
The rate of objectively-confirmed thromboembolic complications (including death attributed to thromboembolic disease) in patients with a score rated as "DVT likely" on a formalized scoring system, when anticoagulation therapy is withheld based on a single, negative comprehensive duplex ultrasound.
Interventions
- OTHER Comprehensive Duplex Ultrasound (diagnostic study)
