NCT00353093

Brief Summary

Currently, patients with suspected deep vein thrombosis (DVT) of the lower extremities receive the ultrasound investigation of their deep vein system, either by limited ultrasonography (ultrasonography confined to the proximal veins, repeating the test after one week in patients with positive D-dimer) or by extended ultrasonography (ultrasonography extented to the entire deep vein system of the legs). No study has directly compared the two strategies to assess their accuracy and safety. We plan to compare the accuracy and safety of the two strategies in a prospective randomized study addressing more than 2000 consecutive outpatients presenting with the clinical suspicion of DVT.

Outcome Measures

Primary Outcomes (6)

  • To assess(1) the prevalence and location of venous thrombosis

  • as shown by the initial diagnostic workup; (2) the rate of

  • symptomatic venous thromboembolic events (including proximal

  • vein thrombosis, isolated thrombosis of the tibial or peroneal

  • veins in either leg, and pulmonary embolism) during three months

  • of follow up in patients with an initially normal diagnostic workup.
