Condition deep vein thrombosis
Treatment exercise
Sponsor University of Oklahoma
Start date October 2008
End date December 2012
Trial size 15 participants
Trial identifier NCT00910364, 14181, ORA #20081607

Summary

The purpose of this pilot study is to assess the feasibility of determining the effects of a structured exercise program started two to four weeks after diagnosis of a first episode lower-extremity deep vein thrombosis (DVT) for a period of 12 weeks in reducing the incidence of post-thrombotic syndrome (PTS).

Additional Information

Official title EXPERT Trial: Exercise to Prevent Post-thrombotic Syndrome Elicited by Recent Thrombosis
Principal investigator Suman W. Rathbun, M.D.
Description Deep Vein Thrombosis (DVT) affects nearly 300,000 people in the U.S. each year. DVT of the leg results in PTS in up to 65% of patients,despite receiving appropriate medical management with anticoagulant therapy. PTS, caused by persistent venous outflow obstruction and venous valvular dysfunction, may result in symptoms of leg pain, swelling, heaviness and cramping especially with prolonged standing. All eligible patients with documented first-episode DVT interested in participating will undergo medical screening and a screening treadmill test prior to enrollment between two and four weeks post DVT diagnosis. All patients will be provided and asked to wear class II (30 to 40mmHg) knee length compression hose daily during the entire trial. The formal exercise training includes both a supervised walking program and a home-based walking program for 12 weeks with follow-up at 26 weeks. Blood tests will be taken to measure levels of indicators of inflammation at baseline, week 4, week 12, and week 26. The primary outcomes will be the feasibility of the exercise program and the incidence of post-thrombotic syndrome at 26 weeks.
