The ERASMUS Study: Limited vs Extended US for DVT Diagnosis - Full Text View

Sponsored by:	University of Padova
Information provided by:	University of Padova
ClinicalTrials.gov Identifier:	NCT00353093

Purpose

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.

Primary Outcome Measures:

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.

Estimated Enrollment:	2000
Study Start Date:	January 2003
Estimated Study Completion Date:	July 2005
