A new NIH-sponsored study – the Chronic Venous Thrombosis: Relief with Adjunctive Catheter-Directed Therapy study, or C-TRACT study – is designed to evaluate whether endovascular therapy procedures improve quality of life for people with long-term complications of deep vein thrombosis (DVT).
Specifically, the C-TRACT study will provide a better understanding of whether endovascular therapy (EVT) procedures, or minimally invasive medical procedures that are performed inside a person’s blood vessels, might reduce the severity of post-thrombotic syndrome (PTS) and improve quality of life among people who are experiencing this complication of DVT.
Researchers involved in the C-TRACT study are seeking individuals with moderate to severe PTS and blockage of the large veins draining the leg to participate in this study. All study participants will receive active, state-of-the-art treatment for their leg problem and be monitored closely. Some patients also may be treated with EVT procedures, such as stent placement.
